Abstract
A raster print engine driver for generating from incoming data representative of a continuous tone or text image, a transition-modulated engine drive signal for causing the engine to reproduce the image as a series of modulated print lines, in which the driver establishes a cell scan time period representing the horizontal length along a print line of an elemental cell print area, and generates from the incoming data in the cell at least zero or two independently located drive signal transitions which cause the print engine to change state at selected points along the print lines to closely reproduce the image.
