Zusammenfassung:	According to an embodiment, a printer (1) includes a thermal head (14) with a plurality of heaters. A memory device (35) stores utilization information indicating a status or cumulative usage amount of the thermal head. A processor (33) is configured to acquire a measured resistance value for each of the heaters in the plurality of heaters and detect whether the thermal head (14) has been changed since a previous use based on differences in the measured resistance values from reference resistance values. If it is detected that the thermal head (14) has been changed, the processor updates the utilization information in the memory device (35) to indicate the thermal head has been replaced.
