PRINTING APPARATUS, PRINTING METHOD, AND COMPUTER READABLE MEDIUM

A printing apparatus includes a thermal head in which a plurality of heating elements is arranged in a main scanning direction, a moving mechanism configured to relatively move a print medium with respect to the thermal head in a sub-scanning direction crossing the main scanning direction, a controller configured to control the thermal head and the moving mechanism, and a storage unit configured to store first print data in which pixels are arranged in the main scanning direction and the sub-scanning direction, the pixels including print pixels indicating pixels with which corresponding dots are formed on the print medium by heat generated by the heating elements and non-print pixels with which no dot is formed on the print medium, the first print data being for printing a first print image represented by the print pixels. The controller executes generation processing and control processing.
