12. A printer comprising:
first and second light sources producing first and second light beams;
at least one modulator for encoding information at an encoding speed onto the first and second light beams, the information corresponding to an image for being printed by the printer;
a plate disposed in the path of the first and second light beams;
a plate mount for supporting the plate, the plate having a resonant frequency of oscillation on the plate mount;
an oscillator for oscillating the plate about an axis of oscillation between first and second angular positions;
at least one reflective surface disposed on the plate;
the first and second light sources being oriented to direct the first and second beams onto the at least one reflective surface to form first and second separate reflected beams that scan synchronously; and
a receiving system for receiving the first and second reflected beams and converting the light of the first and second reflected beams to image information and for printing the image information onto print media.
