PCT No. PCT/DE94/00097 Sec. 371 Date Aug. 2, 1995 Sec. 102(e) Date Aug. 2, 1995 PCT Filed Feb. 1, 1994 PCT Pub. No. WO94/18704 PCT Pub. Date Aug. 18, 1994An optical character generator for an electrographic printer has a plurality of monolithic circuits (11) which are arranged on a carrier (10) and have LEDs (12) which are integrated in the circuits and can be driven individually. The monolithic circuits (11) include a monolithically integrated photodiode drive combination, in the case of which both the associated LEDs (12) and the drive circuit (13), possibly including a BUS circuit (14) for the LEDs (12), are integrated in a monolithic circuit (11). The monolithic circuits are constructed using thin-film technology from III-V semiconductor material, preferably GaAs.
