A resistive ribbon printer, which does not support all-points-addressable (APA) or graphics fonts, is capable of printing APA and graphics data through inactivating the printer's fonts and supplying data serially to the printer from a random-access memory (RAM) when a personal computer (PC) provides signals that such APA and/or graphics data are to be printed. A printer control card 1 produces FNTCLK signals to a font card 2 having fonts A and B therein. The FNTCLK signals cause either characters from the font A or the font B to be supplied to the printer control card 1 from the font card 2.
