Abstract
In a thermal print head employing a line of print elements, temperature sensing is effected by means of an elongated temperature sensing device positioned in parallel with the line of elements and in heat-transfer proximity thereto. The sensor may be of thermo-resistive material and is coupled to a control circuit to effect energy control of drive pulses to the print elements.
