摘要：
A thermal printhead having a temperature regulation feature which is capable of high speed and high quality printing is provided. The thermal printhead includes a substrate, a resistor layer formed on one surface of the substrate, a control section and a thermoelectric element formed in direct contact with the other surface of the substrate opposite to where the resistor layer is formed, wherein the control section is configured to cool the resistor layer using the thermoelectric element.
