A print engine for a pagewidth inkjet printer includes a processor component for programming data transfer. A bus writes and reads data to and from various components of the print engine. A page data interface component is connected to the bus for writing compressed page data to the bus. A memory component is connected to the bus to store page data and program data generated by the processor component. Page expansion and decoding components are connected to the bus to expand and decode the page data. A printhead interface is connected to the bus to receive the expanded and decoded page data and to generate print data for a printhead connected to the printhead interface. |
