Description

  According to the present invention, when print data is temporarily stored using a print server and printing is performed, printing is performed from the printing apparatus by making a print request for the temporarily stored print data from a desired printing apparatus. The present invention relates to control of a printing system that can be made possible.

  Conventionally, a so-called “pull print (accumulated printing)” printing system that enables a user to output print data from the printing apparatus by making a print request to the print data temporarily accumulated on the server from the printing apparatus. Has been proposed. Accordingly, the user can output print data from a desired printing apparatus instead of outputting to a specific printing apparatus when printing from an application.

  For example, Patent Document 1 discloses a conventional pull print system, which discloses a mechanism for printing by designating a temporarily stored print job from the printing apparatus side.

Specifically, when the print data is stored in the job server from the client terminal, an identification number is created by the job server and notified to the client terminal. Then, the user can output from the printer connected to the print server by inputting the identification number from the print server connected to the printer to be output later and making a print request to the job server. is there.

  First, a normal printer driver is installed in each client PC 100, and a logical printer is added. The logical printer has its print destination (print port) set in the print server 200.

  When the user gives a print instruction to the logical printer added to each client PC 100 and whose print destination is set in the print server 200, the pull print of this embodiment is executed. In the present embodiment, the print data transmitted from the printer driver installed on the client PC 100 to the print server 200 is an intermediate file.

  Here, the intermediate file includes, for example, intermediate data in which printing processing of an application program is recorded as a graphic command (GDI command in a Windows (registered trademark) environment) prepared by an OS (operation system) or the like. . This intermediate data is called an enhanced meta file (EMF) in the Windows (registered trademark) environment.

  The intermediate data does not depend on the final print environment (printer model, etc.), and can be converted into printer print data and printed out by the printer according to the final print environment. It is.

  Furthermore, the intermediate data can be created at a higher speed than the print data depending on the printer, and the load on the client PC 100 can be reduced. Hereinafter, the intermediate data is referred to as EMF data.

  The overall flow of pull printing according to this embodiment will be described below.

  FIG. 4 is a schematic diagram illustrating the entire flow of pull printing in the printing system of the present embodiment.

  As shown in FIG. 4, first, the user logs in to the client PC 100 ((1) -1), and the print destination (print port) is designated to the print server 200 from the application program executed on the client PC 100. A print instruction is issued to the logical printer ((1) -2).

  In response to this print instruction, the application program of the client PC 100 transmits data to the printer driver via the graphic engine. The client PC 100 connects to the print server 200 using the LPR protocol, and transmits an intermediate file (hereinafter, print data) received from the application program via the graphic engine ((2) -1). In a predetermined storage location (spool area set in advance) ((2) -2). The print server 200 does not transmit to the printing apparatus even if the print data is stored in the predetermined storage location.

  Next, the print server 200 extracts (generates) bibliographic information data from the print data received from the client PC 100 and stored in the predetermined storage location ((2) -3). The bibliographic information data is transmitted to the print management server 400 and stored in a predetermined storage location (a preset directory) of the print management server 400 using a file sharing mechanism on the network ((3) -1 ). The file name of bibliographic information data stored in a predetermined storage location of the print management server 400 will be described later.

  The print management server 400 monitors the predetermined directory, and when the bibliographic information file is stored in the predetermined directory from the client PC 100, the bibliographic information file is analyzed and the bibliographic information is stored in the bibliographic information DB (of the print management server 400). Registered in the external storage device) ((3) -2).

  When the multifunction device 300 detects an IC card that can be read by the card reader 319, the multifunction device 300 reads the personal authentication information in the IC card, and transmits the read personal authentication information to the print management server 400 as an authentication request (( 4) -1). The personal authentication information is information used for authentication and may be a manufacturing number of the IC card.

  When the print management server 400 receives the personal authentication information from the multi-function peripheral 300, the print management server 400 performs authentication processing of the personal authentication information based on the IC card authentication table stored on the external storage device of the print management server 400, and the authentication result. Is returned to the MFP 300 ((4) -2). If the authentication process is successful, the login user ID of the client PC 100 is transmitted as the authentication result.

  Next, upon receiving an authentication result (login user ID of the client PC 100) indicating that the authentication has succeeded from the print management server 400, the multifunction device 300 transmits a print data list request to the print management server 400 ((5)). -1). Note that the print data list request includes the login user ID of the client PC 100.

  When the print management server 400 receives the print data list request from the multi-function peripheral 300, the print management server 400 searches the bibliographic information DB by using the login user ID included in the print data list request and obtains the print data list corresponding to the login user ID. It is generated and returned to the MFP 300 ((5) -2).

  When the MFP 300 receives the print data list from the print management server 400, the MFP 300 displays the print data list on the UI of the operation unit 308. When the user selects print data and gives a print instruction, the multi-function device 300 transmits a print request (output instruction) for the selected print data to the print management server 400 (6). This print request includes the login user ID of the client PC 100 and the print data time stamp.

  When the print management server 400 receives a print data print request (output instruction) from the MFP 300 (6), the bibliographic information of the print data for which the output instruction has been issued, the login user ID of the client PC 100, and the print data time A search is performed from the bibliographic information DB using the stamp as a key, the print server 200 storing the corresponding print data is identified from the searched bibliographic information, and a print instruction for the corresponding print data is transmitted to the print server 200 ( 7). The print instruction is a print command including the corresponding print data file name.

  Upon receiving a print instruction from the print management server 400, the print server 200 determines (determines) a printer driver corresponding to the output destination multifunction peripheral, and transmits print data to the multifunction peripheral 300 using the LPR protocol based on the print instruction. Then, printing is performed by the multifunction machine 300 (8).

  When the MFP 300 receives print data from the print server 200, the MFP 300 executes print processing. When the printing process is completed, the multi-function device 300 transmits a print completion notification of the completed printing process to the print management server 400 (9).

  The overall flow within the print server 200 will be described below with reference to FIG.

  FIG. 5 is a diagram for explaining the overall flow in the print server 200 shown in FIG.

  As shown in FIG. 5, the virtual printer driver 502 receives print data (intermediate file shown in FIG. 6 described later) from the client PC 100 ((2) -2 in FIG. 4) and saves it in the print data storage area 503. Here, the intermediate file of the present embodiment will be described with reference to FIG.

  As shown in FIG. 6, the intermediate file includes a bibliographic information part 801 and an actual data part 802 (EMF data described above) that is actually printed. In other words, the intermediate file corresponds to a file in which bibliographic information is added to EMF data.

  In this embodiment, the intermediate file is composed of the bibliographic information 801 and the entity data unit 802. However, the bibliographic information 801 and the entity data 802 are individually managed and transmitted separately from the client PC 100 to the print server 200. You may comprise so that.

  In this case, identification information is provided so that the bibliographic information 801 and the entity data 802 are associated with each other.

  Furthermore, when the bibliographic information 801 and the entity data 802 are individually managed and separately transmitted from the client PC 100 to the print server 200, the entity data including identification information that links the intermediate file to the bibliographic information 801 is used. Section 802 (EMF data described above).

  Returning to the description of FIG.

  The print data stored in the print data storage area 503 is extracted from the bibliographic information section 801 (FIG. 6) and the actual data 802 (EMF data) actually printed in the extraction service program 504 for extracting (generating) bibliographic information. (FIG. 6) is extracted ((2) -3 in FIG. 4).

  The bibliographic information is temporarily stored in the bibliographic information storage area 505 and transmitted to the print management server 400 ((3) -1 in FIG. 4). Also, the EMF data is stored in the EMF data storage area 507. The EMF data may be data obtained by deleting the bibliographic information unit 801 from the print data (intermediate file).

  The bibliographic information and the EMF data are linked by a file name or the like. Further, in order to associate the information, information for specifying where the EMF data is stored may be included in the bibliographic information.

  Upon receiving the print instruction information from the print management server 400 ((7) in FIG. 4), the print execution program 508 acquires EMF data from the EMF data storage area 507 based on the information received in the print instruction information. Further, the print execution program 508 selects printer drivers (logical printers) 510 to 512 based on the information received as the print instruction information and the default printer table 506 (FIG. 18), and acquires the acquired information to the selected printer driver. The printed EMF data is handed over to instruct printing output.

  Upon receiving the output instruction, the printer driver (logical printer) converts the EMF data to the MFP 300 and outputs it ((8) in FIG. 4). Note that the output destination is determined by using the IP address of the output destination multifunction peripheral or the IP address determined from the unique name of the output destination multifunction peripheral included in the print instruction information.

  Note that the print execution program 508 can output the output EMF data as a log, and saves the log in the image log storage area 509. The image log may be a data that has a reduced data amount by reduction or the like, such as a thumbnail image.

  The image log may be transmitted to the print management server 400 for management, or may be transmitted to an image log management server (not shown) for centralized log management.

  The virtual printer driver 502, the extraction service program 504, and the print execution program 508 are realized by the CPU of the print server 200 reading out and executing a program stored in the external memory on the RAM.

  The storage areas 503, 504, 507, and 509 are provided in the external memory of the print server 200. Further, the default printer table 506 is also held in the external memory of the print server 200.

  Hereinafter, the overall flow in the print management server 400 will be described with reference to FIG.

  FIG. 7 is a diagram for explaining the overall flow in the print management server 400 shown in FIG.

  As illustrated in FIG. 7, when the authentication program 604 of the print management server 400 receives the authentication information from the multifunction peripheral 300 ((4) -1 in FIG. 4), the authentication program 604 executes authentication processing with reference to the authentication data 605. The authentication result is transmitted to the MFP 300 ((4) -2 in FIG. 4).

  When the print data list program 603 receives a print data list request from the multifunction device 300 ((5) -1 in FIG. 4), the print data list program 603 generates a print data list corresponding to the corresponding user with reference to the bibliographic information DB 602. Then, it is transmitted to the MFP 300 ((5) -2 in FIG. 4).

  Further, when the print instruction program 601 receives an output instruction from the multifunction peripheral 300 ((6) in FIG. 4), the print instruction program 601 stores in which print server the data output from the bibliographic information DB 602 is based on the output instruction information included in the output instruction. Search for bibliographic information indicating whether there is any. Further, the print instruction program 601 transmits to the print server 200 print instruction information including information for specifying the print data instructed to be output and the attribute (for example, IP address) of the MFP 300 that has instructed the output (see FIG. 4 (7)), the output is executed.

  The print instruction program 601, the print data list program 603, and the authentication program 604 are realized when the CPU of the print management server 400 reads and executes a program stored in the external memory on the RAM.

  It is assumed that the bibliographic information DB 602 and the authentication data 605 are held in the external memory of the print management server 400.

  The bibliographic information extraction process of the extraction service program 504 shown in FIG. 5 will be described below with reference to FIGS.

  FIG. 8 is a flowchart showing an example of a first control processing procedure in the print system of the present invention, and corresponds to the bibliographic information extraction processing of the extraction service program 504 of the print server 200 shown in FIG. In the figure, S701 to S708 indicate steps.

  First, in step S701, the extraction service program 504 monitors each area (print data storage area 503) of the intermediate file. The intermediate file is transmitted from each client PC 100 and stored in an intermediate file storage area managed by the print server 200.

  Next, in step S702, the extraction service program 504 determines whether there is a file in the intermediate file storage area. If it is determined that there is no file, the process returns to step S701.

  On the other hand, if the extraction service program 504 determines in step S702 that there is a file in the intermediate file storage area, the extraction service program 504 proceeds to step S703.

  In step S703, the extraction service program 504 loads the file in each intermediate file area onto the RAM.

  In step S704, the extraction service program 504 determines whether the identifier in the header 801 of the file loaded in step S703 matches the identifier indicating the intermediate file. Note that the identifier is assigned by the virtual printer driver of the client PC 100 and includes a unique code that can be identified as an intermediate file.

  If the extraction service program 504 determines in step S704 that the identifier in the header of the file loaded in step S703 does not match the identifier indicating the intermediate file, the process returns to step S701.

  On the other hand, if the extraction service program 504 determines in step S704 that the identifier in the header 801 of the file loaded in step S703 matches the identifier indicating the intermediate file, the process proceeds to step S705.

  In step S705, the extraction service program 504 decomposes the intermediate file into the bibliographic information unit 801 and the entity data unit 802 (EMF data).

  In step S706, the extraction service program 504 transmits the bibliographic information (FIG. 9) disassembled in step S705 to the print management server 400 and registers it in the bibliographic information storage area 505 of the print server 200. For example, when the print data is described in PostScript, the bibliographic information is extracted from the PostScript tag information, and a bibliographic information file (FIG. 9) is generated based on the bibliographic information. You may do it. Here, the bibliographic information file will be described with reference to FIG.

  FIG. 9 shows an example of a bibliographic information file according to the present invention.

  Information extracted as bibliographic information from the intermediate file includes “user (owner) ID”, “document name of print data”, “number of copies”, “number of pages”, “one side or both sides”, “paper size”, “Job identifier”. ".

  Note that “print data storage computer name / IP address” in the bibliographic information file shown in FIG. 9 is the computer name / IP address of the print server 200 itself.

  Further, the “time stamp” in the bibliographic information file shown in FIG. 9 is added by the print management server 400 when it is registered in the bibliographic information DB of the print management server 400.

  The bibliographic information registered in the bibliographic information DB of the print management server 400 may be configured to be deleted at a timing after a certain time after registration. Further, the present invention can be realized without the bibliographic information storage area 505 in the print server 200.

  Returning to the flowchart of FIG.

  In step S707 of FIG. 8, the extraction service program 504 stores the EMF data extracted in step S705 in the EMF data storage area 507.

  Further, in step S708, the extraction service program 504 deletes the intermediate file from each area (print data storage area 503) of the intermediate file, and ends the process.

  Hereinafter, with reference to FIGS. 10 to 13, a pull print process in the multifunction machine 300 illustrated in FIG. 1 will be described.

  FIG. 10 is a flowchart showing an example of a second control processing procedure in the printing system of the present invention, and corresponds to the pull print processing in the multifunction peripheral 300 shown in FIG. Note that the processing of this flowchart is realized by the CPU 301 of the MFP 300 shown in FIG. 3 executing a program read from the ROM 303 or a program read from the HDD 304 onto the RAM 302. In the figure, S401 to S425 indicate each step.

  First, in step S401, the CPU 301 of the multifunction device 300 controls to display a default display screen (not shown) on the display unit of the operation unit 308. In step S402, the card reader 319 causes an authentication card (IC card) to be displayed. It is determined whether or not it has been detected.

  If the CPU 301 of the MFP 300 determines in step S402 that the card reader 319 has detected the authentication card (IC card), the card reader 319 reads data in the authentication card (IC card) in step S403. Then, the card manufacturing number stored in the authentication card as the identification ID is acquired.

  Next, in step S404, the CPU 301 of the MFP 300 sends the IC card authentication request command (FIG. 11C) including the command identifier of the IC card authentication request command and the card manufacturing number acquired in step S403 to the print management server 400. ((4) -1 in FIG. 4), and the process proceeds to step S405. Note that an IC card authentication table (not shown) is stored in the external memory of the print management server 400, and the print management server 400 performs an authentication process based on the card manufacturing number of the IC card received from the MFP 300. It can be carried out.

  FIG. 11 is a diagram illustrating an example of a command transmitted from the MFP 300 illustrated in FIG. 1 to the print management server 400. 12A corresponds to a print data list request command, FIG. 12B corresponds to a print request command or a delete command, and FIG. 12C corresponds to an IC card approval request command.

  Hereinafter, the description returns to the flowchart of FIG.

  Next, in step S405 of FIG. 10, the CPU 301 of the multifunction peripheral 300 determines the authentication result returned from the print management server 400, and if it is determined that the authentication result indicating that the authentication error has occurred is returned. In step S406, the error display screen is controlled to be displayed on the display unit of the operation unit 308. When the OK button 1401 is pressed on the error display screen, the process returns to step S401, and the default screen is displayed again. .

  On the other hand, if the CPU 301 of the MFP 300 acquires the login user ID of the client PC 100 as the authentication result returned from the print management server 400 in step S405, it determines that the authentication is successful (authentication OK). The process proceeds to step S415.

  If the CPU 301 of the MFP 300 determines in step S402 that the card reader 319 has not detected an authentication card (IC card), the keyboard input button is pressed on the default screen in step S407 ( Whether there is a keyboard input instruction). In step S407, if the CPU 301 of the multi-function device 300 determines that a keyboard input instruction has been given, control is performed to display the key input screen shown in FIG. 12 on the display unit of the operation unit 308.

  FIG. 12 is a diagram illustrating an example of a key input screen displayed on the display unit of the operation unit 308 of the multifunction peripheral 300 illustrated in FIG.

  In step S409 in FIG. 10, the CPU 301 of the multifunction peripheral 300 waits for input of the user ID and password on the key input screen, and detects input of the user ID and password on the key input screen. The process proceeds to S410. Specifically, when there is an input instruction to the user ID 901 and the password 902 on the key input screen, the CPU 301 of the multifunction peripheral 300 controls display of a keyboard screen (not shown) on the display unit of the operation unit 308, and displays the keyboard screen. When the user ID 901 and the password 902 are input using the login button 903 or the top screen button 904 as a return button is pressed, the process proceeds to step S410.

  Next, in step S410, the CPU 301 of the MFP 300 determines whether or not the top screen button 904 as a return button has been pressed. If it is determined that the top screen button 904 as a return button has been pressed, The processing is returned to step S401, and the display of the default screen is controlled again.

  On the other hand, if the CPU 301 of the MFP 300 determines in step S410 that the top screen button 904 as the return button has not been pressed, the CPU 301 of the MFP 300 presses the login button 903 in step S411. If it is determined that the login button 903 has not been pressed, the process returns to step S409.

  On the other hand, if the CPU 301 of the multifunction device 300 determines in step S411 that the login button 903 has been pressed, the CPU of the multifunction device 300 in step S412, the user ID and password entered in the user ID 901 and password 902, respectively. Is transmitted to the directory service server 600 as an authentication server via the login service PC 500.

  Next, in step S413, the CPU 301 of the MFP 300 determines the authentication result returned from the directory service server 600 via the login service PC 500, and determines that the authentication result indicating that the authentication is an error has been returned. In step S414, an error display screen (not shown) is controlled to be displayed on the display unit of the operation unit 308. When the OK button is pressed on the error display screen, the process returns to step S401, and the default screen is displayed again. Control display.

  On the other hand, if the CPU 301 of the MFP 300 determines in step S413 that an authentication result indicating that the authentication was successful is returned as the authentication result returned from the print management server 400, the process proceeds to step S415.

  Next, in step S415, the CPU 301 of the multifunction peripheral 300 sends the command identifier and user ID of the print data list request command to the print management server 400 (the user ID returned from the print management server 400 during the authentication process). Or a print data list request command (FIG. 12 (a)) including the user ID transmitted to the directory service server 600) ((5) -1 in FIG. 4), and the process proceeds to step S416. Proceed.

  Next, in step S416 in FIG. 10, the CPU 301 of the multifunction peripheral 300 determines whether or not the print data list data returned from the print management server 400 has been successfully received, and the reception of the print data list data has failed. If it is determined, the process proceeds to step S417, and an error display screen (not shown) is controlled to be displayed on the display unit of the operation unit 308. When the OK button is pressed on the error display screen, the process proceeds to step S418. Then, control is performed so that an empty print data list screen 1000 (FIG. 13, where the print data list 1001 is blank) is displayed on the display unit.

  In another embodiment, an empty print data list screen 1000 may be displayed without displaying an error. In this case, although not shown in the flowchart, when the screen switching button 1002 is continuously pressed twice on the print data list screen 1000, the CPU 301 of the multifunction peripheral 300 again prints a print data list request command (FIG. 11). It is assumed that (a)) is transmitted to the print management server 400.

  On the other hand, if the CPU 301 of the MFP 300 determines in step S416 that the print data list data returned from the print management server 400 has been successfully received, the process proceeds to step S418, and the received print data list data is received. Is controlled to display the print data list data screen (FIG. 13) on the display unit of the operation unit 308, and the process proceeds to step S419.

  Although not shown in the flowchart, if it is determined in step S416 that the CPU 301 of the MFP 300 has received a message indicating no data from the print management server 400 instead of the print data list data, in step S418. Then, control is performed to display an empty print data list data screen on the display unit of the operation unit 308, and a message screen with no data (not shown) is displayed on the empty print data list data screen. Then, when the OK button is pressed on the message screen without data, the screen without data is closed, and control is made to proceed to step S419.

  Note that the print data list screen 1000 shown in FIG. 13 corresponds to a user who has logged in to the MFP 300 and print data that can be printed by the MFP 300 (for details, see the MFP 300 in detail). It corresponds to a screen that displays a list of bibliographic information data corresponding to print data that can be printed (or permitted to be printed).

  In step S419, the CPU 301 of the MFP 300 waits for input of print data selection, print instruction, erase instruction, screen switching instruction, etc. on the print data list screen 1000 (FIG. 13), and print data list screen 1000. If an input at is detected, the process proceeds to step S420.

  FIG. 13 is a diagram illustrating an example of a print data list screen and a layout setting screen displayed on the display unit of the operation unit 308 of the multifunction peripheral 300 illustrated in FIG.

  In the print data list screen 1000, reference numeral 1005 denotes a layout setting button. When this button is pressed (touched), the CPU 301 of the multi-function peripheral 300 shifts the screen to the layout setting screen 1010 and enables layout setting. .

  Hereinafter, the description returns to the flowchart of FIG.

  Next, in step S420, the CPU 301 of the MFP 300 determines whether or not screen switching is instructed by the screen switching button 1002 on the print data list screen. The process proceeds to S421, and control is performed so that another processing screen is displayed on the display unit of the operation unit 308, and the process proceeds to another process.

  On the other hand, when the CPU 301 of the MFP 300 performs layout setting on the print data list screen 1000 in step S420 and the screen setting is instructed by the layout setting button 1003, in step S421, the layout setting screen 1010 (FIG. 13). Is displayed.

  When various setting information is selected and input on the layout setting screen 1010 and the OK button 1011 is instructed to be pressed (touched), the CPU 301 of the MFP 300 stores the layout setting information in the RAM 302, and the process proceeds to S422.

  If it is determined that the print layout setting button 1005 has not been pressed, the process proceeds to step S422.

  Next, in step S <b> 422, the CPU 301 of the multifunction peripheral 300 determines whether a print instruction has been given by the layout setting button 1003 on the print data list screen 1000. If the CPU 301 of the MFP 300 determines in step S422 that a print instruction has been issued, the process advances to step S423 to print the print data selected in the print data list 1001 (as shown in FIG. 11B). , Print request command request information “1”, user ID, data information of the print data selected in the print data list 1001 (for example, document name, job name, time stamp (multiple) determined at the most, etc.), in S421 The set layout information)) is transmitted to the print management server 400 ((6) in FIG. 4), and the process returns to step S415. If a print instruction is issued when no print data is selected in the print data list 1001, a message to select print data is displayed, and then the process returns to step S415.

  On the other hand, if the CPU 301 of the multifunction device 300 determines in step S422 that the print instruction is not issued by the print button 1003 on the print data list screen 1000, the process proceeds to step S424, and the CPU 301 of the multifunction device 300 In the print data list screen 1000, it is determined whether or not an erasure instruction has been given by the erasure button 1004. If the CPU 301 of the MFP 300 determines in step S424 that an erasure instruction has been issued, in step S425, a request to delete the print data selected in the print data list 1001 (as shown in FIG. 15B). Deletion request command request information “2”, user ID, data information of the print data selected from the print data list 1001 (for example, document name, job name, time stamp etc. (several determined), layout information ( In case of deletion, it is empty)))) is transmitted to the print management server 400, and the process returns to step S415. If an erasure instruction is issued when no print data is selected in the print data list 1001, a message to select print data is displayed, and then control is returned to step S415 as it is. And

  Although not shown in the flowchart of FIG. 10, when receiving an error notification indicating that command reception has failed from the print management server 400, the CPU 301 of the multifunction peripheral 300 retransmits the command to the print management server 400. Control to do.

  The print data list generation process in the print data list program 603 of the print management server 400 shown in FIG. 7 and the print instruction process in the print instruction program 601 will be described below with reference to FIGS.

  FIG. 14 is a flowchart showing an example of a fourth control processing procedure in the print system of the present invention, and corresponds to the print data list generation processing in the print data list program 603 of the print management server 400 shown in FIG. In the figure, S1401 to S1406 indicate each step.

  First, in step S1401, the print data list program 603 determines whether a print data list request command (FIG. 11A) has been received from the MFP 300 (the print data list request command is transmitted to S415 in FIG. 10). Applicable).

  If it is determined in step S1401 that the print data list program 603 has not received a print data list request command, the processing in step S1401 is repeated.

  On the other hand, if the print data list program 603 determines in step S1401 that the print data list request command has been received, the process advances to step S1402.

  Next, in step S1402, the print data list program 603 analyzes the received print data list command. In step S1403, based on the analyzed user ID, the corresponding bibliographic information is searched from the bibliographic information DB.

  Each bibliographic information is associated with a user who has performed printing in the bibliographic information DB, and this user is configured to be associated with a user ID obtained by command analysis. Further, the bibliographic information obtained by searching may be configured to be managed by setting a flag so that it is not duplicated.

  In step S1404, the print data list program 603 determines whether bibliographic information (list data) has been acquired in step S1403. If it is determined that the bibliographic information (list data) could not be acquired, the print data list program 603 transmits an error message to the multifunction device 300 (the multifunction device that received the command in S1401) in step S1406, The process ends.

  On the other hand, if the print data list program 603 determines in step S1404 that bibliographic information (list data) has been acquired in step S1403, the process proceeds to step S145. It should be noted that a plurality of bibliographic information can be searched and list data is generated.

In step S1405, the print data list program 603
The bibliographic information (list data) acquired in step S1403 is transmitted to the multifunction device 300 (the multifunction device that has received the command in step S1401), and the process ends.

  FIG. 15 is a flowchart showing an example of a third control processing procedure in the print system of the present invention, and corresponds to the print instruction process in the print instruction program 601 of the print management server 400 shown in FIG. In the figure, S1101 to S1103 indicate each step.

  First, in step S1101, the print instruction program 601 determines whether or not a print request command (FIG. 11B) has been received from the multifunction device 300 (the transmission of the print request command corresponds to S423 in FIG. 10).

  If it is determined in step S1101 that the print instruction program 601 has not received a print request command, the processing in step S1101 is repeated.

  On the other hand, if the print instruction program 601 determines in step S1101 that a print request command has been received, the process advances to step S1102.

  Next, in step S1102, the print instruction program 601 searches for the corresponding bibliographic information from the bibliographic information DB 602 based on the request data information for identifying print data in the print request command (FIG. 11B). get.

  In step S1103, the print instruction program 601 sends print data corresponding to the bibliographic information data to the print execution program 508 in the print server 200 corresponding to the IP address in the bibliographic information data acquired in step S1102. Print instruction information (print instruction) (FIG. 16) is issued to issue a print instruction ((7) in FIG. 4). Note that after the print instruction, the print instruction program 601 deletes the bibliographic information that has been printed from the bibliographic information DB 602.

  Although not shown in this flowchart, if a delete command (FIG. 11B) is received from the multi-function apparatus 300 in step S1101, the print instruction program 601 is used to identify print data in the delete command. Based on the requested data information, the corresponding bibliographic information is retrieved from the bibliographic information DB 602 and acquired. Then, the print instruction program 601 sends the print instruction information (deletion instruction) for the print data corresponding to the bibliographic information data to the print execution program 508 in the print server 200 corresponding to the IP address in the acquired bibliographic information data. ) (FIG. 16) to issue a deletion instruction. After the deletion instruction, the print instruction program 601 deletes the bibliographic information that has been printed from the bibliographic information DB 602.

  FIG. 16 is a diagram illustrating an example of print instruction information transmitted to the print server 200 by the print instruction program 601 of the print management server 400 illustrated in FIG.

  As shown in FIG. 16, the print instruction information includes a print instruction / deletion instruction, an IP address of the multifunction device, a full path of the print data file, layout information, printer description language information, and the like.

  Hereinafter, a print execution process in the print execution program 508 of the print server 200 shown in FIG. 5 will be described with reference to FIG.

  FIG. 17 is a flowchart showing an example of a fifth control processing procedure in the print system of the present invention, and corresponds to the print execution processing in the print execution program 508 of the print server 200 shown in FIG. In the figure, S1301 to S1313 indicate steps.

  First, in step S1301, the print execution program 508 determines whether print instruction information (FIG. 16) has been received from the print management server 400. If the print execution program 508 determines that the print instruction information (FIG. 16) has not been received, the process of step S1301 is repeated.

  On the other hand, if the print execution program 508 determines in step S1301 that the print instruction information (FIG. 16) has been received from the print management server 400, the process advances to step S1302.

  Next, in step S1302, the print execution program 508 analyzes the print instruction information (FIG. 16) received in step S1301, and in step S1303, determines whether the print instruction information is a print instruction or a delete instruction based on the analysis result. judge. If it is determined that the instruction is a deletion instruction, the print execution program 508 advances the process to step S1311, deletes the corresponding print data, and ends the process.

  On the other hand, if the print execution program 508 determines in step S1303 that the print instruction information is a print instruction, the print execution program 508 determines in step S1304 based on the IP address of the MFP in the print instruction information. Search for a printer driver.

Next, in step S1305, print execution program 508, when it is determined that determines whether the appropriate printer driver (logical printer) is present, the appropriate printer driver (logical printer) is present, step The process proceeds to S1307.

  In step S1307, the print execution program 508 selects the corresponding printer driver (logical printer) and advances the process to step S1308.

  On the other hand, if the print execution program 508 determines in step S1305 that the corresponding printer driver (logical printer) does not exist, the process proceeds to step S1306.

  In step S1306, the print execution program 508 refers to the default printer table 506 to determine a printer driver. Specifically, the print execution program 508 acquires a printer driver (logical printer) corresponding to the printer description language information in the print instruction information (FIG. 16) from the default printer table 506, and acquires the printer driver (logical printer). decide. Here, the default printer table 506 will be described with reference to FIG.

  FIG. 18 is a diagram for explaining the default printer table 506 shown in FIG.

  As shown in FIG. 18, the default printer table 506 associates a printer description language (PDL) 901 with a printer driver (logical printer) 902. It is possible to select and determine the corresponding printer driver (logical printer) from the printer description language.

  Hereinafter, the description returns to the flowchart of FIG.

  Next, in step S1311, the print execution program 508 sets the port of the printer driver (logical printer) determined in step S1306 with the IP address obtained in step S1302. When setting a port, the port setting previously set in the printer driver (logical printer) is stored in a storage area such as a RAM or a hard disk. Then, the process proceeds to step S1308.

  In step S1308, the print execution program 508 sets layout information acquired from the received print instruction information in the printer driver (logical printer).

  In step S1309, the print execution program 508 reads the print data (EMF data) from the EMF data storage area 507 based on the file path of the print data acquired from the received print instruction information.

  In step S1310, the print execution program 508 executes LPR printing on the print data (EMF data) read from the EMF data storage area 507. Then, after the print output is completed, the print execution program 508 deletes the EMF data from the EMF data storage area 507.

  More specifically, the print execution program 508 instructs the OS to print EMF data. After the print instruction, the data is passed to the printer driver through GDI (Graphic Device Interface) and output to the multi-function device 300.

  Note that the print instruction is issued to the OS, but the print instruction may be directly issued to the printer driver.

  In step S1312, the print execution program 508 determines whether the output printer driver is a default printer driver. If it is determined that the output printer driver is the default printer driver, in step S1313, the print execution program 508 restores the output port setting of the default printer driver. That is, the setting previously set for the output port of the default printer driver is read from the RAM or the like and set in the default printer driver. Then, the process ends.

  On the other hand, if the print execution program 508 determines in step S1312 that the printer driver output in step S1310 is not the default printer driver, the process is terminated.

  Note that the print execution program 508 may be configured to visualize (for example, convert to PDF) the EMF data before deleting the EMF data and store the visualized EMF data in the image log storage area 509 as an image log. The image log may be a data that has a reduced data amount by reduction or the like, such as a thumbnail image.

  As described above, when the print management server 400 outputs a print instruction designating intermediate file format print data to the print server 200, the printer information (IP address or printer description) received from the printer (multifunction device 300). The print server 200 determines a printer driver (logical printer) to be output based on the printer information and transmits the print data in the meta format by the determined printer driver. (EMF data) can be printed out easily from a desired model and a desired printer.

  Further, by outputting the print data in the intermediate file format, it is possible to configure a system that can output even between printer models having incompatible printer description languages and between devices having different options.

  Further, the layout setting (print setting) is also changed on the printer side, and the user can select the desired model, without knowing which print server the print data is stored in. It is possible to easily print out from a desired printer with a desired print setting.

  In order to properly select the printer driver from the information of the MFP 300 such as the IP address, a printer conventionally required when outputting the print data in the intermediate file format through the printer driver again depending on the model and options The user's work of specifying the driver can be reduced.

  Therefore, even in a system configured by a plurality of printing apparatuses having different printer description languages, device characteristics, and option configurations, the flexible print data stored in a plurality of print servers can be easily output from a desired printing apparatus. A simple pull-print environment.

  Further, it is possible to appropriately change print settings such as layout change on the printer side during output.

  Further, by visualizing the intermediate file, it is possible to save a print image log. Note that this image log may be an image log with a reduced data amount, such as a thumbnail image. Thereby, it is possible to save memory resources for storing image logs.
