A laser printer using a single surface resonant mirror for providing a bi-directional beam sweep. According to a first embodiment, a dual axis mirror 40 uses a first pair of torsional hinges 54A and 54B to provide the resonant beam sweep and a second pair 50A and 50B of torsional hinges provides movement orthogonal to the sweep to maintain successive images of the sweep parallel to each other. A second embodiment uses two single axis mirrors 98 and 102. The first single axis mirror 102 provides the resonant beam sweep and the second 98 provides the orthogonal movement 100 to maintain parallel printed lines of image. This application claims the benefit of U.S. Provisional Application No. 60/378,595, filed on May 7, 2002, entitled Bi-Directional Laser Printing Using a Resonant Scanning Scanning Mirror, which application is hereby incorporated herein by reference.
