Pagewidth inkjet printer with high data rate printer architecture

摘要

A pagewidth inkjet printer includes a support structure. A pagewidth inkjet printhead is mounted on the support structure. A print media feed mechanism feeds print media along an ink path and operatively with respect to the inkjet printhead. An integrated circuit is mounted on the support structure to control operation of the printhead and the feed mechanism. The integrated circuit includes a data and control bus. Interface circuitry is connected to the data and control bus to permit external components to communicate with the data and control bus. Expansion circuitry is connected to the data and control bus to receive and to expand compressed image data. Processing circuitry is connected to the data and control bus to process the expanded image data.
