Abstract
A laser printer includes a Resolution Enhancement driver for causing modulation of image edge pixels. The printer comprises a laser for discharging an electrophotographic surface in accordance with an applied modulation signal. A control processor applies modulation signals to the laser in accordance with received commands. A format controller determines if an image pixel resides at an edge of an image feature and, if so, selects a pixel modification to enhance a representation of the feature edge. The format controller, in conformance with the selected pixel modification, generates an encoded command to the control processor that enables the generation of an appropriate laser modulation signal.
