  • Patent number: 6614459
    Abstract: A thermal printer includes a thermal printhead, a transfer assembly, and a controller. The thermal printhead has an array of heating regions arranged in a primary scanning direction, and a driver for selectively heating the heating regions. The transfer assembly feeds a recording paper in facing relationship to the array of heating regions in a secondary scanning direction perpendicular to the primary scanning direction. The controller is combined with the driver for causing each of the heating regions to selectively form, on the recording paper, differently sized print dots which include an off-dot, a maximum-size dot, and at least one intermediate-size dot.
