Claim 0:
1. A printer comprising:
a printer head configured to operate 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, and 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;
a sensor configured to detect a printing density of a printing pattern printed on the medium; and
a processor configured to
acquire print data,
control the printer head and print the printing pattern on the medium, the printing pattern being set in advance,
in response to detecting the printing density being lower than a printing density set in advance, set an operation mode of the printer head to one of the size change mode or the thickness change mode,
in size change mode, determine 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, print 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, determine 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, print 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.
