In accordance with an embodiment, a printer prints on labels attached to rolled paper at predetermined intervals. The printer includes a sensor that outputs a detection signal where a diameter of the rolled paper is a predetermined value or less. The printer detects, on the basis of the detection signal output from the sensor, a near-end state during an issuing operation of one label. Further, the printer determines, where the near-end state has been detected continuously for a predetermined number or more of labels, that a remaining amount of the rolled paper has been a predetermined amount.

A fixing device shifts to the anomaly detection mode in arbitrary timing except during printing. In the anomaly detection mode, a first heat generation member and a second heat generation member are off and only a third heat generation member is turned on for a predetermined time.
