Thermal-printing device with defective resistive heating element detection mode |
摘要 |
A thermal-printing device prints by selectively supplying a current to a plurality of heat generating elements in accordance with printing data. In a check mode, the thermal-printing device sequentially supplies a check current to the heat generating elements through a light-emitting diode and a current-limiting resistor.
