  • Thermal printer
    Patent number: 10252543
    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.
    Type: Grant
    Filed: June 15, 2017
    Date of Patent: April 9, 2019
    Assignee: FUJITSU COMPONENT LIMITED
    Inventors: Natsumi Uryu, Hiroyuki Kataoka

  • Thermal printer
    Patent number: 9643428
    Abstract: A thermal printer includes heating elements each of which generates heat according to an amount of energy applied thereto, an energy applier that applies energy to each of the heating elements, a memory that stores a gradation table where energy values are set for gradation levels based on a relationship between reflectances of a printed image and amounts of energy applied to the heating elements, and a controller that transfers control data corresponding to gradation levels of image data to the energy applier based on the gradation table to control the amounts of energy to be applied by the energy applier to each of the heating elements.
