Abstract
A printer includes a transportation unit that transports roll paper, a winding unit that winds up the transported roll paper, and a controller that controls the transportation unit and the winding unit. The controller switches between thresholds for a torque limit of the winding unit on the basis of inertia of the winding unit and a speed at which the roll paper is transported when the winding unit winds up the roll paper in synchronization with a transportation operation of the transportation unit.
