Abstract
A digital pulse with modulator is described for use with a Raster-scanning print engine in which a grey scale having a high number of levels, typically at least 63, is described. This modulator reduces the amount of information requiring processing in the input multiple bit image signal by simulating one of the least significant bits as a delay applied to modulate the output print engine signal pulse width. With suitable speed components, a grey scale of at least about 255 levels can be provided.
