A printing apparatus heats a print medium in which color development layers that develop colors in accordance with heating are stacked in correspondence with a plurality of color. The apparatus includes a drive unit configured to drive each of heating elements of a printhead using a first pulse for preheating a predetermined color development layer, and a second pulse applied after the first pulse to cause the predetermined color development layer to develop the color, and a pulse control unit configured to, when developing a specific color, perform a control in which a pulse width of the first pulse is increased and/or a control in which the number of times of application of the second pulse is increased such that another color development layer that is not used to reproduce the specific color does not develop the color.

Printing apparatus and print control method

An apparatus is configured to heat a print medium in which a plurality of color development layers that develop colors in accordance with heating are stacked in correspondence with a plurality of colors so as to form an image on the medium by causing a desired color development layer in the plurality of color development layers to independently develop the color. The apparatus includes a printhead, an input unit configured to receive a print job, a generation unit configured to generate image data and cut information for specifying a cut position, a second generation unit configured to generate first and second pulses for driving the print head, and a drive unit configured to drive the print head to form an image on the medium and apply heat beyond a melting point to melt the medium so as to cut the medium.
