A technique is described whereby a single drive mechanism is used to select and move only one ribbon at a time in a multi-colored ribbon cartridge. Printers which require printing in multiple colors often use a stuffer box cartridge in which each of many colored ribbons are continuously turning. Proper selection of the ribbon takes place by raising or lowering the cartridge. The technique of a single drive allows driving wheel 10, driven by drive motor 11, to engage driven wheels 12 of only the ribbon segment selected. This takes place at the time cartridge 13 is positioned up or down for the printing of the selected color. Therefore, only the selected ribbon is turning during the printing operation, increasing reliability and reducing the power required to drive the ribbons.
