摘要： A thermal printer having a thermal printhead with energy save features which is capable of high speed and high quality printing is provided. The thermal printer has an energy storage device and a thermal printhead including a substrate, a resistor layer formed on one surface of the substrate, and a thermoelectric element disposed on the other surface of the substrate opposite to where the resistor layer is formed, wherein the thermoelectric element converts heat generated by the resistor layer to electrical energy when a temperature difference between the resistor layer and an opposite side of the thermoelectric element where the resistor layer is disposed nearby becomes large enough for the thermoelectric element to convert heat into electric energy, and the electrical energy is stored in the energy storage device.
