ABSTRACT:
In a thermal transfer printer of the type wherein pigment or dye on the thermal transfer paper is transferred onto the recording paper by means of a thermal print head, a plurality of current pulses having a sufficiently small time width are seriated closely to produce a contiguous current supplied to each of thermal elements of the print head. It is detected whether any current pulse flows at least in one of the thermal elements, and the current conducting operation is terminated when none of the thermal elements is found to conduct the current pulse. The printer can terminate the recording operation in the course of any line that none of the thermal elements conducts the current any longer, and proceed to the recording operation for the next line, whereby the printing time can be reduced.
