Print system for a pagewidth printer for expanding and printing compressed images

摘要

This invention provides for a print system for a pagewidth printer. The print system includes a central processing unit (CPU) subsystem having a CPU with a plurality of peripherals configured to interface said print system with the printer and to control operation of the printer. Also included is a dynamic random access memory (DRAM) subsystem configured to store print data and to arbitrate requests received from the CPU subsystem, and a print engine pipeline (PEP) subsystem configured to accept compressed pages from the DRAM subsystem and to render said pages to bi-level dots for printing by a bi-lithic printhead of the pagewidth printer.
