In label printing, the "thermal print head" is a key component of the label printing equipment. Usually the shape of a long bar, the thermal print head determines how wide of a print area your thermal label printer can cover. A thermal print head has a row of heat actuating pixels, controlled by a computer, which work together with the rest of the printer to transfer the ink onto the label to create an image. The thermal print head has no moving parts, and works entirely by heating up individual pixels.
