Abstract
A multiple raster image processor (RIP) system is described that enables faster system performance over multiple processors, and includes a zero RIP feature consisting of a language interpreter sub-RIP that interprets a print instruction file but does not process the graphics rendering steps or the post-language processing operators. A skip RIP interprets selected pages in a way that skips all or most of the processing for that page. Pages to be skipped are scheduled for a different processor, thereby saving processing time and enabling the provision of a multiple processor RIP.
