Abstract
A printer for use with both monochrome and color ink ribbon cartridges has a cartridge holder which is rotatable to correctly position the ink ribbon of whichever cartridge is put in place in front of the print head. The cartridge holder and a transmission for driving it are mounted on a carriage which is movable in front of a platen. A driving motor for powering the transmission is placed on the carriage to convert the printer from monochrome so as to be able to use with either a monochrome or a color ink ribbon cartridge and a switch having two sets of contacts in a single circuit responds to the presence of a color ink ribbon cartridge to position the color ribbon in front of the printer at a color home position.
