Abstract
The invention is directed to a method of transmitting data from a host computer to a printer. Image data is provided which represents at least a portion of a print image to be printed by the printer. Locations of absolute zero values in the image data and locations of non-absolute zero values in the image data are defined. The locations of the absolute zero values and the locations of the non-absolute zero values are mutually exclusive from each other. Both the host computer and the printer are instructed of the locations of the absolute zero values in the image data. Only the image data having non-absolute zero values is transmitted from the host computer to the printer.
