Claim 8:
9. A non-transitory computer readable medium configured to store instructions, which, when executed by a processor, cause operations to be carried out, the operations comprising:
operating the printer head in a normal mode for printing print data on a medium with at least one of a designated size or a designated thickness of a character, or operating the printer head in one of a size change mode or a thickness change mode for printing the print data on the medium with a size or thickness of the character being greater than the designated size or the designated thickness, respectively;
detecting, by the sensor, a printing density of a printing pattern printed on the medium;
acquiring, by the processor, print data;
controlling, by the processor, the printer head and printing the printing pattern on the medium, the printing pattern being set in advance; and in response to detecting the printing density being lower than a printing density set in advance, setting, by the processor, an operation mode of the printer head to one of the size change mode or the thickness change mode, in size change mode, determining whether there is a character set to a maximum size in the print data, and when there is a character set to a maximum size, printing the print data so that the character designated to have the maximum size is of the designated size of the character, and characters other than the designated character have a character size one step higher than the designated size of the character, and in thickness change mode, determining whether there is a character set to a maximum thickness in the print data, and when there is a character set to a maximum thickness, printing the print data so that the character designated to have the maximum thickness is of the designated thickness of the character, and characters other than the designated character have a thickness of the character one step higher than the designated thickness of the character.
