Abstract
A thermal printer includes a control part; a thermal head that is heated upon a heating instruction from the control part and stops heating upon a heating-ending instruction from the control part; a temperature detector that detects a temperature of the thermal head upon a temperature detection instruction from the control part; and a feed motor that is driven upon a conveyance instruction from the control part and stops the conveyance upon a conveyance-ending instruction from the control part. The control part issues, prior to printing, the heating instruction and the conveyance instruction such that the heating of the thermal head and the conveyance of the paper are performed in parallel. The control part issues the temperature detection instruction as an interrupt every predetermined period of time after the heating instruction is issued, and issues the heating-ending instruction when the temperature of the thermal head reaches a predetermined preheat-ending temperature.
