Patent ID: 8896646

Claim:
A printer, comprising: a printing unit having a platen roller rotatably supported around a shaft; a power unit including a stepping motor, and a gear train to drive the stepping motor to transfer a force generated by the stepping motor to the platen roller and rotate the platen roller around the shaft; a cutting unit provided at a further downstream of a forward direction than the platen roller to cut a paper at a certain position, the forward direction in which the paper printed by the printing unit is fed by a forward rotation of the platen roller; and a control unit to control a driving of the stepping motor and an operation of the cutting unit, wherein the control unit is configured to drive the stepping motor by a first number of steps to rotate the platen roller forward and place a certain portion of the paper at a predetermined position of the cutting unit on standby for a predetermined time, and then control the cutting unit to cut the paper, and after the cutting, drive the stepping motor by a second number of steps to rotate the platen roller forward, the second number of steps being a minimal number of steps necessary to remove backlash of the gear train.
