Abstract
Disclosed are a printer and a method of switching ribbon tracks of an ink ribbon. The printer uses an ink ribbon having a plurality of ribbon tracks of the same color and properly switches the ribbon tracks from one to another in a printing operation. This ribbon-track switching method switches the ribbon tracks from one to another when a printing page is changed or an equivalent operation is executed. It is therefore possible to suppress a decrease in printing density to thereby prolong the service life of the ink-ribbon cartridge. Since the ribbon tracks are switched from one to another when a printing page is changed or an equivalent operation is executed, thus inhibiting the switching of the ribbon tracks on the same page, the printing density on the same page becomes even and the printing quality can be improved.
