ABSTRACT:
A print engine controller for a pagewidth printhead includes contone and bi-level decompression circuitry for decompressing a contone layer of compressed page data and a bi-level layer of compressed page data, respectively; halftoner and compositor circuitry for halftoning the decompressed contone layer to associated bi-level versions and compositing the decompressed bi-level layer over the halftoned contone layers; printhead interface circuitry for receiving the halftoned and composited data, and to generate therefrom print data suitable for printing by the printhead; and line loader and formatter circuitry for receiving dot data from the halftoner and compositor circuitry, loading dot data for a given print line into buffer storages, and formatting the dots of the given print line into an order required by the printhead interface circuitry. The line loader and formatter circuitry loads the dot data into a combination of on integrated circuit and external storage buffers.
