Abstract
A printer includes a printing unit having a platen roller, a power unit including a stepping motor and a gear train, a cutting unit provided at a further downstream of a forward direction than the platen roller to cut a paper at a predetermined position, the forward direction in which the paper printed by the printing unit is fed by the forward rotation of the platen roller, and a control unit to control the driving of the stepping motor and the operation of the cutting unit. The control circuit controls the platen roller to rotate forward and place a certain portion of the paper at a predetermined position of the cutting unit on standby for a predetermined time, then controls the cutting unit to cut the paper, and after the cutting, controls the platen roller to rotate forward by a minimal number of steps necessary to remove backlash.
