A method of manufacturing a cartridge selectively for multicolor and single color ribbons is disclosed in which the cartridge body is formed with a projection to co-act with a ribbon shift mechanism on a printer to continuously shift a single color ribbon. When the cartridge is loaded with a multi-color ribbon, the projection is broken away and a selectively operable ribbon shift cam mechanism is mounted in the cartridge.
