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 printing density of letters or the like so that the voltage to be impressed upon the exothermic elements of a heat-sensitive head is controlled together with the voltage impressing time in response to the detected output.
