    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： A printer is provided having a carrier, a printhead having a plurality of nozzles, at least one of the nozzles being rotationally displaced relative to the carrier, and a controller for determining and communicating print data to the nozzles. The controller is configured to determine the rotational displacement, determine a correction factor for compensating for a printing error caused by the determined rotational displacement, and alter the print data based on the correction factor to at least partially compensate for the rotational displacement. The correction factor is at least partially based on a thickness of media being printed on.

    摘要： A printer controller is provided for supplying ejection data to a printhead mounted to a carrier and having a plurality of ejection nozzles. The printer controller is configured to determine a rotational displacement of the printhead relative to the carrier, determine a correction factor at least partially based on a thickness of media being printed on so as to at least partially compensate for the determined rotational displacement, and alter the supply of the ejection data based on the correction factor.

    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.
