A raster print engine driver (10) for generating from incoming data representative of a continuous tone (20) or text (22) image, a transition-modulated engine drive signal for causing the engine (18) to reproduce the image (14) as a series of modulated print lines, in which the driver establishes a cell scan time period representing the horizontal length (42 of figure 3B) along a print line or an elemental cell print area (42 of figure 3B), and generates from the incoming data in the cell at least zero or two independently located drive signal transitions which cause the print engine (18) to change state at selected points along the print lines to closely reproduce the image (14). |
