  FIG. 7 is a diagram showing a configuration of a JDF (job description file).

  In FIG. 7, the JDF 701 includes header information 702, management information 703 such as a unique ID and file owner, print attribute information 704 such as page settings, print history information 705, color management information 706, and cutting / folding specifications 707. Is done. The print history information 705 is managed for each version of the document 708, and includes a user name 709, a print date and time 710, a print status 711 indicating whether printing has been normally completed or canceled, a print start page 712, and a print end page 713. Is done.

  FIG. 8 is a flowchart showing the procedure of the printing process executed by the image forming system shown in FIG.

  This process is executed by the CPU 201 in FIG. 2, the CPU 301 in FIG. 3, and the main CPU 401 in FIG.

  In FIG. 8, first, the information processing apparatus designates the print range 502, the JDF storage location 508, the document version 509, and the number of copies 511 designated by the user via the print UI 501 in FIG. Then, the information processing apparatus designates print attribute information such as print settings set via the print setting UI 601 in FIG. 6 (step S801) (print attribute setting means, job description file storage location setting means). Subsequently, the information processing apparatus associates the print target file with the JDF storage location in FIG. 7 (first association unit). Examples of the association method include a method of embedding the JDF storage location set via the setting screen of FIG. 5 in the data of the print target file (S802).

  In step S803, the information processing apparatus generates (converts) a PDL (job description language) that can be interpreted by the printer, based on the drawing data of the print target file and the print attribute information. In step S804, the information processing apparatus transmits to the print server 102. The PDL, print attribute, and JDF storage location are transmitted (first transmission means). In this system, a print server for generating JDF is provided for each network, and when a print process is instructed by each client PC, the printer driver sets the PDL, print attribute information, and JDF storage location. The information shown is transmitted to a predetermined print server. However, when the client PC has a function of generating JDF, the processing from S804 to S807 executed by the print server may be omitted.

  In step S805, the print server 102 receives the PDL, print attribute information, and JDF storage location, and generates image data and JDF 701 (first receiving means, image data generating means, job description file generating means). . In step S806, the print server 102 stores the generated JDF 701 in the specified storage location (job description file storage unit). In step S807, the print server 102 transmits the image data and the JDF 701 to the printer 103 (second transmission unit). It is assumed that the print server 102 has a rasterizing function for analyzing PDL and generating image data. Further, the print server 102 generates a JDF based on the received print attribute information. At this time, the print server 102 adds management information to the generated JDF. The JDF 701 transmitted to the printer 103 is described in a format that can be interpreted by the printer.

  A process when the client PC has a function of generating a JDF will be described. If the client PC can generate the JDF, the JDF is generated from the print attribute information set via the UI shown in FIGS. Then, the client PC saves the generated JDF in the location specified in the JDF save location in FIG. The storage location may be any device that can communicate with the client PC, and may be stored in the memory 202 of the client PC.

  Next, the printer 103 receives the image data and the JDF, and executes printing (step S808) (second receiving unit, print execution unit), and whether the printing has been canceled by a user operation or due to an error or the like. It is determined whether or not (step S809).

  As a result of the determination in step S809, if there is no cancellation and the processing ends normally, the printer 103 notifies the print server 102 that the printing has ended normally (end status) (step S810) (printing end notification means). In S810, when the printer receives the PDL from the client PC, the printer notifies the client PC corresponding to the PDL transmission source of the normal end.

In step S811, the print server 102 registers, in the print history information 705 of the JDF 701, the print status 711, the print start page 712, the print start page 712, and the print end page 713. (History registration means). On the other hand, the same applies when the client PC receives from the printer that printing has been completed normally. Specific processing in S811 will be described. When the print server 102 (or client PC) stores the JDF in the storage destination designated in step S806, the print server 102 (or client PC) copies and stores the storage JDF. The print server 102 (or client PC) appends the print processing result to the JDF of the held copy, and stores the appended JDF in the storage destination again. As a result, the JDF held by the processing of S806 is overwritten by the JDF for copying, so that it is possible to manage the JDF in which the print processing result is described.
In step S812, the print server 102 determines whether to save the generated image data. When the generated image data is not stored in the print server 102, this process is terminated. Whether or not image data is to be saved is determined by, for example, providing a “save image data” check box in the UI displayed by selecting the “finishing” tab of the print setting UI 601 shown in FIG. If the print server receives the PDL generated by checking the check box, the print server determines to save the image data in S812. On the other hand, when the client PC transmits the PDL to the printer and executes print processing, if “Save image data” is checked, the image data is generated by receiving the image data generated by the printer. Can be saved. If the result of determination in step S809 is that printing has been cancelled, the printer 103 notifies the print server 102 that printing has been canceled and the range in which output has been completed (step S813) (printing end notifying means). The print history additional registration process after step S811 is executed, and this process ends. The processes of S811 and S813 will be described in detail. The printer can measure the number of output pages every time one page is output. The printer notifies the print server of the measurement result (also referred to as processing information). The print server 102 identifies the range where the output has been completed based on the print output start page specified by the print range included in the received PDL and the number of output pages received from the printer, and additional registration processing of the print history Execute. In S813, it is described that the printer notifies the print server. However, when the print server executes print processing using the PDL transmitted from the client PC without generating JDF, the printer performs print processing on the client PC. Is notified of the interruption and the number of completed pages.

  In step 811, the print server 10 cancels the print status 711 in the print history attribute 705 of the JDF 701, prints the print start page 712, and prints normally on the print end page 713. Reregister JDF with the end page as the end page (history registration means). On the other hand, when the client PC generates JDF, the client PC executes the process of S811.

  As a result of the determination in step S812, when the generated image data is stored in the print server, the print server 102 (or client PC) associates the image data with the JDF storage location (step S814) (step S814). 2), this process is terminated.

  According to the processing in FIG. 8, the print history information can be centrally managed for each file by giving the print history information to the JDF attribute (step S811). Thus, the user can surely and easily perform confirmation of the already printed printing range and the number of copies and designation of the printing range.

  The effect when executing the processing of the present application will be specifically described. For example, it is assumed that a print process is executed using a portable “notebook PC-A”. In addition, since it is stored in its own memory as the JDF storage location, “notebook PC-A” is selected as the JDF storage location. In this case, when the printing process is performed halfway in the network environment 1, a JDF indicating that the printing process has been performed halfway is stored in the memory of the notebook PC-A. In this situation, the “notebook PC-A” is connected to the network 2 that is not connected to the network environment 1. In this case, since the output history information of the file to be printed is described in the notebook PC-A, it is possible to specify and output an unprinted page range desired by the user even in different network environments.

  FIG. 9 is a flowchart showing a procedure of print range setting processing executed by the client PC 101 of FIG.

  This process is executed by the CPU 201 in FIG. Hereinafter, a procedure for designating the print range 502 using the history reference 507 will be described. The client PC 101 manages the JDF storage location for each file. Therefore, the client PC 101 can identify the storage area associated with the specified file in response to the user specifying the file. Then, the client PC 101 reads the JDF from the identified storage area, thereby enabling the processing in FIG.

  In FIG. 9, when the client PC recognizes the history reference 507 instruction via the print UI 501 by the user (step S901), the client PC acquires the print history information 705 of the JDF 701 (step S902), and displays the printed range list information. Generate (step S903). Since the client PC manages the JDF storage location designated for each print target file, the client PC reads the JDF storage location of the currently selected print target file from the memory 202. Then, the client PC can realize the processing of S902 by accessing the storage location of the read JDF. When the client PC 101 stores JDF in its own memory, the print history information is read from its own memory.

  Next, the client PC 101 detects an unprinted range from the print history information 705 (step S904), and generates unprinted range list information (step S905). The client PC can recognize the total number of pages of the currently selected print target file. The client PC can generate unprinted range list information by detecting the difference between the recognized total number of pages of the print target file and the printed range list information created in S903. On the other hand, the printed range list information can be detected by referring to the JDF.

  The client PC displays the UI as shown in FIGS. 10 and 11 on the output device 205 using the printed range list information and the unprinted range list information (step S906) (history information display means).

  Next, the client PC selects a desired print range from the printed range list or the unprinted range list selected by the user via FIG. 10 or FIG. 11 (step S907). As a selection method, there is a method of selecting a desired list with a mouse as shown in FIG. Finally, when the OK button 1101 is pressed (step S908), the range selected in step S907 is set as the print range.

  According to the process of FIG. 9, a printed page or an unprinted page in the print target file can be designated accurately.

  The present invention is not limited to the above embodiment. When a file for which JDF has already been generated is to be printed, the print attribute already registered and overwritten with the print attribute specified in step S801 in the flowchart of FIG. 8 is overwritten. If a location different from the JDF storage location already associated with the file is set as the JDF storage location, in step S806, the already stored JDF is moved to the newly set storage location.

  Further, when the image data is stored in the print server 102 in the process of step S813 in the flowchart of FIG. 8, the image data may be the print target. In this case, steps S803, S804, and S805 are omitted.
