Printers are known in which the typefont is located in a cartridge assembly, thus providing for convenient typefont replacement through a mere drop-in type of operation. However, different typefonts having different characteristics should be usable on the same machine, and such machine should be able to discriminate between one typefont cartridge and another or, in other words, to identify the cartridge being used.
