Abstract

<P>PROBLEM TO BE SOLVED: To realize the execution of higher-speed preflight. <P>SOLUTION: In carrying out preflight of input PDL, if PDL information is already acquired by interpreting once, the PDL information is stored in a log file, and from the next time, preflight is carried out on the basis of the information written in the log file. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an information processing apparatus, a management apparatus, a control method thereof, and a storage medium for storing them.

  Usually, preflight check checks the contents of PDF and points out any warnings (contents) that are not suitable for printing. In the current preflight check, in addition to the PDF information, warning information that includes information on the target device to be output and the RIP system is presented to the user, but the target printer and system are not changed without changing the PDF content. Even when was changed, a new PDF interpretation was performed and a preflight check was performed, resulting in a waste of processing.

Further, as another conventional example, for example, Patent Document 1 can be cited.

  An object of the present invention is to introduce a preflight log file in order to solve the above-described problems, and aims at faster preflight.

  Start preflight, first determine whether there is a log file associated with the PDL to be preflighted, and if there is a log file, enter the PDL, log file, printer information, and host environment for RIP A step, a step to check if the log file is the log file of the input PDL, and if so, a step to check if the log file has been edited illegally, and if not, read the log file Steps for acquiring PDL information, steps for checking whether the same information as the input environmental law remains in the log file, and if not, warning information is input from the input environmental information and the preflight result. Step to create, step to display PDL information and warning information as needed, and this time to log file A step of appending a pre-flight information, the preflight check processing method using the log files comprising the step of modifying the PDL as needed based on the warning information is used.

  When preflighting the input PDL using the method described above, if the PDL information has already been acquired by interpreting it once, it will be written to the log file from the next time by saving it in the log file. Preflight can be performed based on the information that is available, so it has become possible to perform preflight much faster than before. In addition, memory saving is realized in the sense that no interpreter is used.

(Example 1)
Next, Example 1 will be described.

  FIG. 1 is a block diagram showing a basic configuration according to the present embodiment.

  In FIG. 1, reference numeral 1 denotes a CPU, that is, a central processing unit, which controls the entire apparatus and performs arithmetic processing. Reference numeral 2 denotes a RAM, that is, a random access memory, which is an area where each program and data is loaded and executed for each process. Reference numeral 3 denotes a ROM, that is, a read-only memory, which is a storage area for system control programs, input PDL, intermediate PDL, image data, ID table, and the like. Reference numeral 4 denotes KBC, that is, a keyboard control unit, which receives data by key input from the keyboard 5 (KB) and transmits it to the CPU 1. Reference numeral 6 denotes a PRTC, that is, a printer control unit, for controlling the printer device 7 (PRT). The printer device 7 is a laser beam printer, an ink jet printer, or the like. Reference numeral 8 denotes a CRTC, that is, a display control unit, which performs display control on the display device 9 (CRT). Reference numeral 10 denotes a DKC, that is, a disk control unit, which controls data transmission and the like. 11 is an external storage device such as an FD (flexible disk device), HD (hard disk device), or CD (CD-ROM), which stores programs and data, and loads them to the RAM 2 as needed during execution. . Reference numeral 12 denotes a system bus, which should be a data transfer path between the above-described components.

  This apparatus operates when the CPU 1 executes a preflight check process using a basic I / O (input / output) program, an OS (operating system), and a log file described below.

  The basic I / O program is stored in ROM3, and the OS is written in HD11. When the power of this apparatus is turned on, the OS is read from the HD 11 into the RAM 2 by the IPL (Initial Program Loading) function in the basic I / O program, and the operation of the OS is started.

  In this embodiment, preflight check processing using log files and related data are recorded in FD11 or CD-ROM11 as shown in FIG. 2, and this FD11 or CD-ROM11 is stored in FD drive or CD-ROM drive. As shown in FIG. 3, the preflight check processing program and related data using the log file recorded in can be installed on the HD11 of this apparatus through the FD drive or CD-ROM drive. In this case, when the FD11 or CD-ROM11 is set in the FD drive or CD-ROM drive, the preflight check processing using log files and related data are controlled under the control of the OS and basic I / O program. Is read from and installed in HD11 and can be operated. FIG. 4 shows a memory map in a state where the preflight check processing program using the log file is installed in the HD 11 and can be executed. FIG. 5 is a flowchart in this embodiment.

  First, in step 1, it is confirmed whether there is a log file attached to the target PDL. In other words, it is determined whether the PDL is the first preflight. If No, the process jumps to Step 13, and if Yes, the PDL to be preflighted, the log file, and the environment information are input. Environmental information refers to the type and ability of the printer to be output, and the ability of the host to perform RIP, such as fonts and ICC profiles. Next, in step 3, it is confirmed whether the input log file is of the input PDL. This can be done, for example, by comparing the file-specific file ID entered this time with the file ID of the PDF file obtained when the previous preflight was performed, to confirm whether the previous PDF and the current PDF are the same. Is. If this is No, the process jumps to Step 12, and if Yes, it is confirmed in Step 4 whether the log file has been illegally edited. As an example of the confirmation method, it is determined whether the date and time of the previous preflight written in the log file match the file update date of the file itself. If this is No, the process jumps to Step 12, and if Yes, in Step 5, the input PDL information is acquired from the log file. Next, in step 6, it is confirmed whether there has been a preflight performed under the same conditions as the current environmental information among several preflights so far. If this is No, in step 8, based on the input environment information, warning information is created based on the previous PDL information and environment information, and the process jumps to step 9. If yes, in step 7, warning information remaining in the log file is set and the process jumps to step 9. In step 9, PDL information and warning information are displayed as necessary. Next, in step 10, the preflight information performed this time is added to the log file. If Step 3 and Step 4 are No, the input log file is discarded in Step 12, and if Step 1 is No and Step 13 after Step 12, the PDL is interpreted and the input PDL Get information. Next, in step 14, warning information is created based on the input environment information and the PDL information obtained in step 13. Next, in step 15, PDL information and warning information are displayed as necessary. In step 16, a log file is created and preflight information performed this time is described. Finally, as the next step after steps 10 and 16, the PDL is corrected as necessary based on the warning information.

1 is a configuration diagram of an information processing apparatus according to a first embodiment. It is a figure which shows the recording content of FD or CD-ROM. FIG. 3 is a relationship diagram of an FD or CD-ROM and an information processing apparatus. It is a figure which shows the memory map of the information processing apparatus when the preflight check process using a log file is installed in the hard disk of the information processing apparatus. 6 is a flowchart illustrating a preflight check process using a log file according to the first embodiment.
