Abstract
A printer which includes a position controller for moving a printing head to a predetermined initial position by driving a stepping motor during initial processing operation, and a current controller for supplying a second current to the stepping motor to spontaneously start the stepping motor. Since the stepping motor is driven by the second current which is smaller than a first current to be supplied during printing, the noise to be produced during the initial homing operation can be minimized.
