Abstract
A thermal printer includes heating elements that generate heat according to amounts of applied energy, an energy applier that applies energy to the heating elements, a memory that stores a gradation table where energy levels to be applied to the heating elements are set for gradation levels based on a relationship between dot area ratios of an image and the amounts of energy applied to the heating elements, and a controller that transfers control data multiple times to the energy applier based on the gradation table to control the amounts of energy to be applied by the energy applier to the heating elements, each of the control data corresponding to different amounts of energy.
