Abstract

PURPOSE:To maintain the printing quality similar to that at room temperature at all times irrespective of the variations in the surrounding temperature by detecting the temperature around a printing so that the voltage to be impressed upon exothermic elements of a heat-sensitive head is controlled together with the voltage impressing time in response to the detected output.
