Abstract
In a printing apparatus, a printer control unit transmits image data to an engine control unit for a respective one of a plurality of bands sent by a host computer. The image data of the respective one of the plurality of bands defines a pattern of 'M' dots by 'N' lines related to an image of a corresponding band where both 'M' and 'N' denote an integer. The printer control unit transmits a band information command to the engine control unit prior to the transmission of the image data. The band information command includes a band height, a print start dot position and a print end dot position, the band height indicative of a quantity of the image data transmitted, the print start dot position indicative of a position of a print start dot with respect to all the 'N' lines in the image, and the print end dot position indicative of a position of a print end dot with respect to all the 'N' lines in the image.
