<P>PROBLEM TO BE SOLVED: To efficiently process a printing instruction expressed by a page description language when a plurality of drawing processing means performs parallel processing for each page. <P>SOLUTION: A whole print job consisting of a plurality of pages described in a page description language which is not page-independent, is transmitted to drawing processing units 531Y-533Y. When receiving a processing request command for specifying which page in the print job should be subjected to image processing, a RIP control part 52Y distributes a processing request command to the drawing processing units 531Y-533Y capable of distributing processing request command in ascending order in which a page specified by a processing request command distributed next time follows a page specified by the processing request command distributed last time. In the drawing processing units 531Y-533Y, the print job of the page specified by the processing request command distributed by the RIP control part 52Y is developed to image data to form printing data. <P>COPYRIGHT: (C)2013,JPO&INPIT |
