Abstract: PURPOSE:To make correct printing possible even when the rates of relative movements of a printing head and the surface to be printed are different, by providing a print control circuit for applying the printing head with signal synchronously with a print driving signal synchronously with a pulse generated from an encoder. CONSTITUTION:When position count data has been zero, a slip position control circuit 26 issues printing start-up pulses PN to synchronously cause printing command signals PC to be at a high level. The print control citcuit 25 causes a driving circuit 29 to output a print driving signal PM synchronous with an encorder clock signal EC2 outputted from an encorder clock circuit 23, and a printing head 21 prints a dot matrix. When the printing is completed and the tip of the next slip 16b is detected, the control part 27 sets position count information PT in the circuit 26 and stops the rotation of a motor 10. After the temporary suspension of the motor, when speed command information VS of low speed rotation is supplied, the motor rotates at a low speed. Again pulses appear in the encorder clock signal EC2 to perform printing.
