とを特徴とする熱転写式プリンタ。 A transfer ribbon repeatedly coated with multiple colors of ink in the longitudinal direction is moved in one direction while the transfer paper is reciprocated, and a thermal head is used to create a thermal pattern at the position where the transfer ribbon and the transfer paper overlap. In a thermal transfer printer that performs multicolor printing by sequentially overlapping and transferring the plurality of color inks onto the transfer paper, a temperature detection means for detecting the temperature of the thermal head, and a detection result of the temperature detection means. determining means for determining the energization time of the thermal head based on the color change; and determining means for determining whether the temperature of the thermal head immediately before changing colors and starting printing exceeds a preset temperature; The thermal head is energized according to the determined energization time, and if the previous temperature exceeds the preset temperature, after changing the color and starting printing, the thermal head is energized for a predetermined period of time. , and energization control means for energizing the thermal head for a longer period of time than the determined time.
