Post-processing apparatus for extracting received print data and forwarding the received print data to an image forming apparatus for processing

摘要

When there is no post-processing performed in a post-processing device, a print job of original PDL data of a general-purpose data structure is output from a computer to a PDL control unit of an image forming device. While, when there is post-processing performed in the post-processing device, a print job of PDL data of an extended data structure generated by adding attribute data of the post-processing is output from the computer to an extended PDL control unit of the post-processing device. Then, the extended PDL control unit extracts the original PDL data of the general-purpose data structure and the attribute data of the post-processing, from the received print job. The attribute data of the post-processing is used for the post-processing control unit to control a post-processing unit. The original PDL data of the general-purpose data structure is output to the PDL control unit of the image forming device.

1. A printing system comprising:
a processor; an image former configured to print original image data; and a post-processor configured to post-process a printed sheet of the image former, wherein:
the processor is configured to generate:
original page description language (PDL) data regarding a print of the original image data, based on a setting item related to the image former, andpost-processing PDL data based on a setting item related to the post-processor,the processor is further configured to send a print job of PDL data including the original PDL data and the post-processing PDL data to the post-processor,the post-processor is configured to extract the post-processing PDL data from the print job,the post-processor is further configured to send the original PDL data without the post-processing PDL data to the image former,the image former is configured to print the original image data based on the original PDL data,the image former is further configured to feed the printed sheet to the post-processor, andthe post-processor is further configured to post-processes the printed sheet based on the post-processing PDL data.
