ABSTRACT:
A thermal transfer type printer consists of a thermal head, a platen roller, a printing control circuit, a reflection type photo sensor, a printing paper, and a transfer film on which thermal melting ink is painted. One of at least two kinds of printing papers is selectively used. The printing paper and the transfer film are lapped and pressurized between the thermal heat and the platen roller when the printing operation is performed. The intensity of light reflected by the printing paper varies in accordance with the kind of the printing paper which is actually used. The photo sensor emits the light to the printing paper and outputs a detection signal corresponding to the intensity of the light refleted by the printing paper. The printing control circuit changes the heating values of the heating elements within the thermal head based on the detection signal. Thus, the thermal head is heated to an optimum temperature in response to the kind of printing paper.
