A replaceable ribbon cartridge for printers is disclosed and which has a user controllable re-inking capability. The cartridge includes both an ink transfer roller and a drive roller, both of which contact the advancing ribbon during printing operations. Also, a re-inking roller is provided, and the re-inking roller is laterally moveable so as to permit the user to selectively move the re-inking roller to a neutral position wherein it has no substantial contact with either the ink transfer roller or the drive roller, to a first operative position wherein the re-inking roller is in substantial contact only with the ink transfer roller, or to a second operative position wherein the re-inking roller is in contact with both the ink transfer roller and the drive roller.
