Abstract
A printer accesses from a bit mapped raster matrix of an image to be printed, a group of bits corresponding in number to the number of printing elements of the printhead. This group of bits is used to drive the printing elements of the printhead so as to print the image. In the printers having raster scanning printheads, the selected groups of bits are accessed from the bit mapped raster matrix synchronously with the raster scanning of the printhead.
