ABSTRACT:
A laser printer includes at least three laser beams for simultaneously scanning a rotatable recording medium. The laser beams have their centers spaced uniform or non-uniform distances from each other. The centers of the laser beams are spaced predetermined distances from each other so that the print resolution may be 300, 400, 600, or 1,200 dpi depending upon the laser beams selected for use with at least two laser beams always being selected.
