Zusammenfassung:	A printer includes a printing head, a take-up driving device, a take-up amount detecting portion, a constant torque control device, and a switching control portion. The take-up driving device drives a take-up portion for taking up at least a part of layers of the recording medium fed by a feeder on an outer circumference part and forming a roll. The take-up amount detecting portion detects a take-up amount by the take-up portion. The constant torque control device performs constant torque control that sets a driving torque of the take-up driving device to a constant value corresponding to an input command value. The switching control portion switches the command value in stages in accordance with an increase in the take-up amount detected by the take-up amount detecting portion associated with an advancement of the take-up by the take-up portion.
