A printer belt drive control circuit comprises: an encoder count circuit (4) for counting output signals from a drive encoder (11) attached to a drive motor (10) and from a motor encoder attached to a belt motor (6), a servo controller which under control of a CPU (1) and outputs a rotation speed information of the belt motor (6) according to tan output signal from the encoder count circuit (4), and a motor drive signal generation circuit for converting an output information from the servo controller (2) into a form appropriate for an H-bridge driver circuit (5) which directly drives the belt motor (6).
