    摘要: A print engine is provided having printhead modules and a controller. Each printhead module has a plurality of ejection nozzles. The nozzles of at least one of the printhead modules is rotationally displaced relative to the other printhead modules. The controller communicates ejection data to the ejection nozzles in accordance with a cumulative correction factor for each printhead module, including printhead modules having non-rotationally displaced nozzles, to at least partially compensate for the rotational displacement.

    摘要: Provided is a print engine pipeline subsystem of a printer controller. The subsystem includes a print engine pipeline controller for reading and writing print engine pipeline registers, and a contone decoder unit for expanding JPEG compressed continuous tone (“contone”) layers. Also included are a lossless bi-level decoder for expanding compressed bi-level layers, a line loader unit for expanding page images for a printhead, and a printhead interface for sending dot data to the printhead and for providing line synchronization between multiple printer controllers.
