ABSTRACT OF THE DISCLOSURE An optical printer comprises a mechanical scanner, which scans a modulated light beam across a recording medium in a main or horizontal direction at a fixed speed. An acousto-optic deflector performs auxiliary scanning of the beam in a vertical direction onto the mechanical scanner at a constant rate and is connected to a deflection signa? generator. The deflection signal generator adjusts the stroke length of auxiliary scan in accordance with the ma?nification ratio and simult?neously adjusts the frequency of aux???ary scanning by the reciprocal of the magnification rate of the character to be printed. Furthermore, optical density is maintained constant for various character sizes by providing auxiliary gate pulses proportional to the square of the relative character size, which are AND gated with a character information signal to effect a light modulation signal for modulating the beam.
