1. Field of the Invention
The present invention relates to an image forming apparatus which discharges, to a designated discharge device among a plurality of discharge devices, a printing medium printed based on print data, a control method therefor, and a program.
2. Description of the Related Art
When printing an image including personal information, like a form or direct mail, conventional image forming apparatuses print while individually processing variable data formed from information common between records, and information different between records, like the address and name.
Variable data is data (data formed from information which changes between records) generated based on information managed in a database. Variable data is sometimes created as part of print data by an image editing apparatus, and transmitted to an image forming apparatus.
Image data common between records is generally stored as form image data in the internal storage device of an image forming apparatus while a corresponding job is processed. The common image data is composited with image data formed from information different between pages or records, and then printed.
Conventional image forming apparatuses generally include a plurality of discharge devices for externally discharging a printed material bearing an image. The function of the discharge device changes depending on the application purpose of the discharge device.
For example, a discharge device having a function of storing a large volume of printed materials has a cover to inhibit taking out or touching printed materials from the outside during printing in order to stably hold many printed materials.
There is a specific discharge device for discharging a printed material of a specific page or specific record during printing in order to check the printed state. The specific discharge device allows the operator of an image forming apparatus to easily view a printed material or take it out even during printing.
In a conventional printing system, when discharging a printed material of a specific page or specific record to a specific discharge device during printing in order to check the printed state, a printed material bearing the same image as that of a final product is discharged to the discharge device.
As disclosed in Japanese Patent Laid-Open No. 10-329398, a technique of replacing variable data in print data with specific data before outputting a form has conventionally been applied to confirm the printed image of the form.
However, according to the conventional technique, one other than an operator who performs print processing may view or take out a printed material for checking the printed state during printing.
Particularly when a printed material bearing an image including confidential information or personal information, like a form or direct mail, falls into the hands of a person not permitted to view the printed material, the confidential information or personal information may leak from the printing system. The conventional technique suffers such a security hole in the printing system.
If printing continues without checking the printed state, in order to prevent the leakage of confidential information and personal information, the operator cannot grasp degradation of the print quality upon a change of the state of the printing apparatus over time. This may result in a poor-quality final product.
The present invention has been made to overcome the conventional drawbacks, and has as its object to provide an image forming apparatus capable of reducing the chance to view a printed material by a person permitted to perform a print operation when the printed material is discharged to a specific discharge device, and reducing the chance to leak confidential information and personal information from a printing system, a control method therefor, and a program.

When the image forming apparatus 1002 is activated, it shifts to data reception standby step S12001.
In step S12001, the network control unit 2006 determines whether the image forming apparatus 1002 has received print data from an external device. If the network control unit 2006 determines that the image forming apparatus 1002 has not received print data (NO in step S12001), the process waits until the image forming apparatus 1002 receives print data. If the network control unit 2006 determines that the image forming apparatus 1002 has received print data (YES in step S12001), the process shifts to step S12002.
An example of the print data is one including the first image data common between pages or records, and the second image data different between pages or records.
In step S12002, the job ticket analysis unit 2010 analyzes the print data received from the external device, and upon completion of analyzing print data of one page, the process shifts to step S12003. In step S12002, whether a page to be printed includes variable data can be determined by analyzing the print data 8001 or 11001 by the job ticket analysis unit 2010. For example, in
In step S12003, the PDL interpreter/RIP processing unit 2011 generates image data to be printed on the page analyzed in step S12002. In step S12003, the PDL interpreter/RIP processing unit 2011 individually generates common data defined as image data common between records or pages, and image data of variable data defined by the database file 9001. When the data management unit 2009 manages in advance image data generated in step S12003, like a form image, image data managed by the data management unit 2009 can be applied.
In step S12004, the CPU 4005 determines whether the operator designates, via the operation unit 1004 or the operation window 7000 of the job generating unit 2003, discharge of the page analyzed in step S12002 to the sample tray 1007.
If the CPU 4005 determines in step S12004 that the operator does not designate discharge of the page analyzed in step S12002 to the sample tray 1007 (NO in step S12004), the process shifts to step S12005.
In step S12005, the image processing unit 4017 composites image data of common data and that of variable data which have been generated in step S12003, generating bitmap image data. When print data does not include variable data, bitmap image data of only common data is generated without executing composition processing by the image processing unit 4017.
In step S12006, the printer 4023 transfers the image data generated in step S12005 onto a sheet.
In step S12007, the stacker 1005 discharges the sheet printed in step S12006 to the stacking portion 1006.
In step S12008, the CPU 4005 determines whether all pages included in the print data have been processed. If the CPU 4005 determines that all pages included in the print data have not been processed (NO in step S12008), the process shifts to step S12002 to continue print data analysis processing.
If the CPU 4005 determines in step S12004 that the operator designates discharge of the page analyzed in step S12002 to the sample tray 1007 (YES in step S12004), the process shifts to step S12009.
In step S12009, the job ticket analysis unit 2010 determines whether the image data generated in step S12003 includes variable data. The method of determining whether image data includes variable data has been described in step S12002, and a description thereof will not be repeated.
If the job ticket analysis unit 2010 determines in step S12009 that the image data generated in step S12003 does not include variable data (NO in step S12009), the process shifts to step S12014.
If the job ticket analysis unit 2010 determines in step S12009 that the image data generated in step S12003 includes variable data (YES in step S12009), the process shifts to step S12010.
In step S12010, the job ticket analysis unit 2010 determines whether the variable data generated in step S12003 includes personal information.
If the job ticket analysis unit 2010 determines in step S12010 that the variable data generated in step S12003 does not include personal information (NO in step S12010), the process shifts to step S12014.
In step S12014, the image processing unit 4017 composites image data of common data and that of variable data which have been generated in step S12003, generating bitmap image data.
If the job ticket analysis unit 2010 determines in step S12010 that the variable data generated in step S12003 includes personal information (YES in step S12010), the process shifts to step S12011.
In step S12011, the job ticket analysis unit 2010 determines whether the print data received in step S12001 includes the sample data 11003. Whether print data includes sample data can be determined by determining whether the print data has the sample data identifier 11006.
If the job ticket analysis unit 2010 determines in step S12011 that the print data received in step S12001 includes the sample data 11003 (YES in step S12011), the process shifts to step S12015.
In step S12015, the image processing unit 4017 composites image data of common data and that of sample data, generating bitmap image data.
If the job ticket analysis unit 2010 determines in step S12011 that the print data received in step S12001 does not include the sample data 11003 (NO in step S12011), the process shifts to step S12012.
In step S12012, the job ticket analysis unit 2010 determines whether the image data generated in step S12003 is formed from only variable data.
If the job ticket analysis unit 2010 determines in step S12012 that the image data generated in step S12003 is formed from only variable data (YES in step S12012), the process shifts to step S12013.
In step S12013, the CPU 4005 sets, as image data of a page to be printed, specific image data (patch sheet image) which is managed in advance in the data management unit 2009 to measure an output density.
If the job ticket analysis unit 2010 determines in step S12012 that the image data generated in step S12003 is not formed from only variable data (NO in step S12012), the process shifts to step S12016.
In step S12016, the CPU 4005 sets, as image data of a page to be printed, only image data of common data (i.e., image data other than image data (second image data) of variable data).
In step S12017, the printer 4023 transfers, onto a sheet, an image generated in one of steps S12013 to S12016.

If the job ticket analysis unit 2010 determines in step S13002 that the image data has not been generated based on a character string included in the database file 9001 (NO in step S13002), the process shifts to step S13003.
In step S13003, the job ticket analysis unit 2010 determines whether the image data has been generated based on link data (e.g., the instruction 8007 in
If the job ticket analysis unit 2010 determines in step S13003 that the image data has been generated based on link data of image data included in the database file 9001 (YES in step S13003), the process shifts to step S13004.
If the job ticket analysis unit 2010 determines in step S13003 that the image data has not been generated based on link data of image data included in the database file 9001 (NO in step S13003), the process shifts to step S13007. In step S13007, the job ticket analysis unit 2010 determines that the analyzed image data is not personal information, and ends the image data analysis processing.
In step S13004, the job ticket analysis unit 2010 searches the image data management table 10001 in
If the job ticket analysis unit 2010 determines in step S13004 that the image data is registered in the image data management table 10001 (YES in step S13004), the process shifts to step S13007. In step S13007, the job ticket analysis unit 2010 determines that the analyzed image data is not personal information, and ends the image data analysis processing.
If the job ticket analysis unit 2010 determines in step S13004 that the image data is not registered in the image data management table 10001 (NO in step S13004), the process shifts to step S13005.
In step S13005, the job ticket analysis unit 2010 registers the image data in the image data management table 10001, and the process shifts to step S13006. In step S13006, the job ticket analysis unit 2010 determines that the analyzed image data is personal information, and ends the image data analysis processing.
As described above, according to the first embodiment, when discharging a printed material to a specific discharge device during printing in order to check the printed state, it is controlled to print neither confidential information nor personal information.
The first embodiment can reduce the chance to view a printed material by a person permitted to perform a print operation when the printed material is discharged to a specific discharge device, and reduce the chance to leak confidential information and personal information from a printing system.

As described above, in addition to the effects described in the first embodiment, the second embodiment can reduce the possibility of taking out, from a printing system, a printing medium bearing confidential information or personal information.
The embodiments have been described in detail. The present invention can take embodiments of a system, apparatus, method, program, storage medium, and the like.
The present invention can reduce the chance to view a printed material by a person permitted to perform a print operation when the printed material is discharged to a specific discharge device, and reduce the chance to leak confidential information and personal information from a printing system.
Note that the present invention can be applied to an apparatus comprising a single device or to system constituted by a plurality of devices.
Furthermore, the invention can be implemented by supplying a software program, which implements the functions of the foregoing embodiments, directly or indirectly to a system or apparatus, reading the supplied program code with a computer of the system or apparatus, and then executing the program code. In this case, so long as the system or apparatus has the functions of the program, the mode of implementation need not rely upon a program.
Accordingly, since the functions of the present invention are implemented by computer, the program code installed in the computer also implements the present invention. In other words, the claims of the present invention also cover a computer program for the purpose of implementing the functions of the present invention.
In this case, so long as the system or apparatus has the functions of the program, the program may be executed in any form, such as an object code, a program executed by an interpreter, or script data supplied to an operating system.
Example of storage media that can be used for supplying the program are a floppy disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a CD-RW, a magnetic tape, a non-volatile type memory card, a ROM, and a DVD (DVD-ROM and a DVD-R).
As for the method of supplying the program, a client computer can be connected to a website on the Internet using a browser of the client computer, and the computer program of the present invention or an automatically-installable compressed file of the program can be downloaded to a recording medium such as a hard disk. Further, the program of the present invention can be supplied by dividing the program code constituting the program into a plurality of files and downloading the files from different websites. In other words, a WWW (World Wide Web) server that downloads, to multiple users, the program files that implement the functions of the present invention by computer is also covered by the claims of the present invention.
It is also possible to encrypt and store the program of the present invention on a storage medium such as a CD-ROM, distribute the storage medium to users, allow users who meet certain requirements to download decryption key information from a website via the Internet, and allow these users to decrypt the encrypted program by using the key information, whereby the program is installed in the user computer.
Besides the cases where the aforementioned functions according to the embodiments are implemented by executing the read program by computer, an operating system or the like running on the computer may perform all or a part of the actual processing so that the functions of the foregoing embodiments can be implemented by this processing.
Furthermore, after the program read from the storage medium is written to a function expansion board inserted into the computer or to a memory provided in a function expansion unit connected to the computer, a CPU or the like mounted on the function expansion board or function expansion unit performs all or a part of the actual processing so that the functions of the foregoing embodiments can be implemented by this processing.
While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
