Abstract: A printing apparatus includes: a power supply unit configured to supply electric power to a print head configured to perform printing based on rendering data, a control device which includes a rendering data generation module configured to generate the rendering data from print data provided from a host device, and a separate device which is a device other than the print head and the control device; and a distribution unit configured to distribute the electric power supplied by the power supply unit to the control device, the print head, and the separate device.

Abstract: A control device includes: a print data acquisition unit configured to acquire print data, which is formed of a plurality of lines and indicates a coloration state of each pixel included in the plurality of lines; a head drive unit configured to supply, to a thermal head formed of a plurality of heating elements each corresponding to the pixel, an electric current for heating the thermal head for each pixel; a motor drive unit configured to supply, to a motor configured to move heat-sensitive paper relative to the thermal head, a drive current for step driving the motor for each line; a speed control unit configured to control, based on the number of colored pixels of a determination subject line among yet-to-be-printed lines of the print data, a relative moving speed of the heat-sensitive paper moved by the motor; and a preheating control unit configured to cause the head drive unit to output, when the determination subject line is a specific line being a line in which the number of colored pixels of the det
