PROBLEM TO BE SOLVED: To provide a thermal printer that can perform high speed printing while having a good gradation property.SOLUTION: A thermal printer includes: a heating element that prints data with multi-gradation when energy is applied; and an IC for applying energy to the heating element. The IC, if a gradation level is within an intermediate density region, adds constant energy Eto apply to the heating element whenever the gradation level becomes higher, and, in a saturation density region in which the gradation level is higher than that in the intermediate density region, applies energy Ethat is greater than the energy E. |
