    摘要: An inkjet printer is provided which has a printhead module and printer controller. The printhead module has a plurality of inkjet nozzles, with at least one of the nozzles being rotationally displaced relative to a carrier of the printhead module. The printer controller determines and communicates ink dot data to the inkjet nozzles, and is configured to determine the rotational displacement, determine at least one correction factor that at least partially compensates for an error in ink dot displacement caused by the determined rotational displacement, and alter the output of the ink dots 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: 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.
