  • Page parallel RIP and cache tuning in print/copy job environment utilizing page description languages
    Patent number: 8233185
    Abstract: What is provided are a system and method for print/copy job environments utilizing a page description language (PDL). In one embodiment, an input PDL stream describing embedded objects in a job is received and parsed. Reusable document components (RDCs) are identified. A determination is made as to how many placements are in the PDL for each identified RDC. If no RDCs are placed more than once, caching is disabled. If it is not efficient to split the PDL stream into smaller tasks, page parallel rip (PPR) is disabled. The embedded objects are analyzed to determine a number of PPRs for the job based on system resources. A raster image processing (RIP) time is projected for each path in the job based on the determined number of placements and the determined number of PPRs. A job processing path is prescribed for the job based on the most efficient projected RIP time.
