A printer has a print unit, a printer communicator, printer storage, and a printer controller. The controller controls the printer communicator to receive a print command that includes character data and a font command. The controller acquires font data for characters specified by the character data based on font data and relational information stored by the printer storage 21. The controller generates print data by applying a specific process related to the font type and controls the print unit based on the generated print data to print on a print medium.
