ABSTRACT:
A compatible thermal head includes multiple heat generating elements arranged in a row on a substrate, and multiple drive devices, selectively coupled to the heat generating elements, for driving a corresponding at least one of the heat generating elements. The quantity of drive devices is less than the quantity of heat generating elements. Also included in the thermal head are a strobe signal input device for receiving multiple external strobe signals as input, and a number-of-strobe-signals converting device, integral to the thermal head and coupled to the strobe signal input device, for converting the multiple external strobe signals received by the strobe signal input device into multiple internal strobe signals. The quantity of the internal strobe signals is greater than the quantity of the external strobe signals. The number-of-strobe-signals converting device supplies the internal strobe signals to corresponding ones of the drive devices to cause the drive devices to drive the corresponding at least one heat generating element in accordance with the internal strobe signal.
