FIELD: computer engineering, in particular, output of alphanumeric, symbolic and graphic information. SUBSTANCE: device has drive, carriage with printing head, and carriage driving mechanism. Goal of invention is achieved by design of drive as direct current electric motor with digital system for rotational frequency regulation. Regulation system has rotation frequency code setter, pulse generator, pulse counter, pulse detector of electric motor rotation speed, which is mechanically connected to motor shaft, matching circuit, electronic gate, which is connected in series too electric motor power supply circuit. EFFECT: improved printing quality in different modes, possibility to operate in severe conditions. 2 cl, 3 dwg
