ABSTRACT:
In one embodiment, the present invention provides a scan line controller for use with a laser scanning device. The scan line controller includes a pulse width modulator system to receive a pulse code, including a first pulse width modulator to receive a first dot clock and a second pulse width modulator to receive a second dot clock, and to provide a video driver signal to a laser unit to provide a scan line from the video driver signal. The scan line controller further includes a space insertion/deletion unit configured to adjust a scan line length by inserting or deleting one or more delays into the first and the second dot clocks.
