Description

  The present invention relates to a printing system that processes one print request using a plurality of types of page description languages.

  Conventionally, one print request (hereinafter referred to as a print job) transmitted from the image information processing apparatus to the image forming apparatus is defined by one type of page description language. Therefore, the image forming apparatus processes one received print job from the beginning to the end in one type of page description language. On the other hand, certain types of page description languages can express various commands and excel at drawing, while other types of page description languages have fewer commands and faster throughput, making them suitable for text systems. The page description language has unique features.

In addition, depending on the print job, there are cases where figures are inserted in several places in a long sentence. Both the page description language that is excellent for drawing graphics and the page description language that is suitable for text systems It also occurs when you want to use. In such a case, according to the conventional technique, if the page description language is changed, it is determined that the job is interrupted, and the previous processing portion is printed out. As a result, even a printed material that is preferably output as a single printed material is output as a plurality of printed materials. Various techniques for effectively using a plurality of types of page description languages are also disclosed (for example, see Patent Document 1).

Step S2-12
Emulation (B) (FIG. 8) returns to the previous analysis state based on the analysis state storage means 23-1 (FIG. 8). However, since the previous state is not yet stored, it is ignored here.

Step S2-13
If the data analysis for the specified size stored in step S2-11 is completed, the process proceeds to step S2-17. If the analysis is not completed, the process proceeds to step S2-14. Here, since the data analysis for the specified size has not been completed yet, the process proceeds to step S2-14.

Step S2-14
The emulation (B) reads the data section via the data reading unit 13 (FIG. 8). Here, data section 33-3 (1) (part of command 1B (FIG. 9)) is read.
Step S2-15
The emulation (B) executes command analysis with the page description language as B.

Step S2-16
Steps S2-13 to S2-16 are repeated until the analysis of one command is completed, and when the analysis of one command is completed (one command is established), the process returns to step S2-18. Here, since all of the command 1B has not been analyzed, the process returns to step S2-13. If the analysis of all the data sizes notified in step S2-11 is completed when the process returns to step S2-13, the process proceeds to step S2-17. Here, since the data size of a part of the command 1B (33-3 (1) in FIG. 9) has been completed, the process proceeds to step S2-17 via step S2-13.

Step S2-17
Since the data size notified in step S2-11 (here, a part of the command 1B) has ended in the emulation (B), the analysis state storage means 23-1 (see FIG. 8) is saved, and the process returns to step S2-5. In emulation (A), steps S2-5 to S2-10 are repeated twice, and after the analysis of command 3A and command 4A is completed, the process proceeds from step S2-9 to step S2-11. Next, steps S2-11 to S2-16 are repeated for the remaining part of command 1B (data section 33-3 (2) (FIG. 2)), and the remaining part of command 1B is analyzed. Then, it is added to the data section 33-3 (1) (FIG. 9), and the command 1B is established. Therefore, the process proceeds to step S2-18.

Step S2-18
Since the command 1B is established, the process returns to the step S2-5 through the steps S2-13 and S2-17 (in this case, the analysis state storage area mode 40-1 (FIG. 10 is stored when the analysis is completed)). Steps S2-5 to S2-10 are repeated again, and after the analysis of the data section 30-6 (command 5A (FIG. 9)) is completed, the process returns to step S2-6, and from step S2-6 to step S2-19. move on.
Step S2-19
The analysis result of emulation (A) and the analysis result of emulation (B) are processed (printed) as one image data, and the flow ends.

  As described above, according to this embodiment, even if the command converted by the second page description language B is divided in the middle of a series of commands, the analysis of the data section including a part of the command is completed. At this point, it becomes possible to save the analysis state, so that it is possible to analyze the remaining part of the command that follows (not necessarily immediately after) and restore the command. As a result, it is not always necessary to include one command in one data section, and an effect is obtained that the degree of freedom increases in the configuration of the transmission frame.
