ABSTRACT:
A printing head according to the present invention resets the count value of a counter in response to an externally supplied signal, and thereafter, counts a signal supplied upon input of an image signal. A decoder generates a selection signal in accordance with the count value, thereby selecting a divided heat-generating element group in units of 32 clocks. Furthermore, an electric current is supplied to heat-generating resistors which belong to the selected heat-generating element group, thereby performing a printing operation. With this printing head, a printer, which can be controlled by a smaller number of control signals, can be realized.
