  • Network print server with page-parallel decomposing
    Patent number: 6084688
    Abstract: A network printing system is available to a large population of users submitting jobs thereto at random times. The system includes a first decomposer facility, such as for PostScript.TM. or PDF interpretation, and a second decomposer facility, such as for PCL interpretation. The first decomposer facility is capable of parallel interpretation of multiple page images within a job, while the second decomposer facility may not be. A buffer manager arbitrates the operation of the decomposer facilities, so that page images of different page description languages or other image formats are processed optimally.
