プリンタ。 A thermal printer having an ink ribbon, a thermal head that heats and melts the ink of the ink ribbon, a temperature sensing element attached to the thermal head, and a controller that controls the thermal head etc. prints an arbitrary line. At this time, head temperature information is provided by a temperature sensing element attached to the thermal head, a voltage dividing circuit that converts the resistance value of the temperature sensing element into voltage, and an A/D converter that converts the converted voltage into binary data. The head temperature information is fetched multiple times from the fetch circuit, and compared with the head temperature information of the previous printing which is stored in advance in the memory section, and the data with the smallest difference is set as the head temperature information of the current printing. thermal printer.
