Abstract
This invention can substantially equally distribute a load necessary for rendering, and can complete printing all pages of one print job at high speed. A master printer interprets received print data, generates display list data as intermediate data for each page, and upon completion of generating intermediate data of all pages, transfers them to a slave printer. The master printer performs rendering (RIP) in an ascending page order of page numbers 1, 2, . . . , whereas the slave printer performs rendering in a descending page order from the final page. When the number of rendered pages held by the master printer does not reach half of all pages upon completion of rendering all pages, the master printer receives the rendering results of deficient pages from the slave printer. Then, each printer prints by almost the same number of pages.
