Printer, control method of the printer, and thermosensitive medium

Abstract

A printer includes a thermal head and a controller. The thermal head performs thermal printing on a thermosensitive medium having a background area with a background color being an unprinted color and a pre-print area, which is an area colored in advance, with a pre-print color different from the background color. The controller performs printing processing of causing the thermal head to execute the thermal printing in which a print area, which includes at least a part of the pre-print area, of the thermosensitive medium is printed with a print color different from both the background color and the pre-print color, and an overlapping area of the pre-print area, which overlaps with the print area, is printed with a specific color different from the pre-print color.
