A multi-color ink ribbon cassette for use on a color printer includes a plastic film which is positioned between a multi-color ink ribbon and a print head to prevent print wires from being soiled with ink, thereby preventing a color mixture on the ink ribbon. With reference to the figure, a cassette 1 associated with a print head 11 contains a multi-color ink ribbon 2 having plural strings bearing different color ink. The ribbon 2 is pulled out of a store cavity 10 by a drive roller 7 which cooperates with a frictional roller 8. A pressure plate 9, provided at an exit port of the cavity 10, gives appropriate tension to the ribbon 2. The ribbon 2 passes by the tip of the print head 11 comprising print wires.
