ABSTRACT:
Disclosed herein is a method of printing a document image with a host computer and an associated printer, where the printer has a printhead with a plurality of laterally-spaced dot columns. The method includes rasterizing the document image in the host computer to produce raster-formatted data representing the document image. This data is then segregated into data swaths corresponding to swaths of the printhead, and further segregating into dot-column data blocks corresponding to printhead dot columns. The dot-column data blocks are then sent to the printer in the order in which they will be processed by printhead electronics within the printer. The printer passes the dot-column data blocks to the printhead to control firing of printhead's nozzles.
