Abstract

A ribbon cartridge for printing apparatus is provided selectively with a color selection mechanism, when the cartridge is loaded with a multi-color ribbon, operated by moving the printer-carriage to a position beyond the print line limit and with a peg arranged to engage a cam mechanism on the print carriage, when the cartridge is loaded with a single color ribbon, to enable the full width of the ribbon to be utilized. The peg is formed integrally with the cartridge and is removed when a multi color ribbon is to be loaded in the cartridge.
