Abstract
An embodiment of the present invention provides a printer configured to print on a print medium. The printer includes a thermal head and a control unit. The thermal head has a plurality of heating elements that are arranged in a line. The control unit is configured to control thermal energy to be applied to the plurality of heating elements, in accordance with information based on image data. The information includes whether to apply a pulse of energizing current in each of a plurality of periods being preset during a scanning line time for one line. The plurality of periods is set in an order from a long period to a short period during the scanning line time.
Claims16
A printer configured to print on a print medium, the printer comprising:
- a thermal head comprising a plurality of heating elements that are arranged in a line;
- and
- a processor configured to control thermal energy to be applied to the plurality of heating elements in accordance with information based on image data, the information including whether to apply a pulse of energizing current in each of a plurality of periods that are preset during a scanning line time for one line, wherein:
- the plurality of periods are set in an order from a long period to a short period during the scanning line time, and
- the plurality of periods include four periods and a period length ratio of the four periods is 8:4:2:1.
A printing control method of a printer that is configured to print on a print medium by using a thermal head comprising a plurality of heating elements arranged in a line, the printing control method comprising:
- sequentially transferring data of each line in image data;
- and
- determining, based on information on whether to print a target dot of a print target line and information on whether to print dots of previous and next lines of the print target line corresponding to the target dot, whether to apply respective pulses of energizing current in each of a plurality of periods with respect to each dot of a print target line, wherein:
- the plurality of periods are preset during a scanning line time for one line,
- the plurality of periods are set in an order from a long period to a short period during the scanning line time, and
- the plurality of periods include four periods and a period length ratio of the four periods is 8:4:2:1.
A non-transitory storage medium storing a program that is configured to cause a computer to execute a method to print on a print medium by using a thermal head comprising a plurality of heating elements that are arranged in a line, the method comprising:
- sequentially transferring data of each line in image data;
- and
- determining, based on information on whether to print a target dot of a print target line and information on whether to print dots of previous and next lines of the print target line, whether to apply respective pulses of energizing current in each of a plurality of periods with respect to each dot of a print target line, wherein:
- the plurality of periods are preset during a scanning line time for one line,
- the plurality of periods are set in an order from a long period to a short period during the scanning line time, and
- the plurality of periods include four periods and a period length ratio of the four periods is 8:4:2:1.
