Abstract: The present invention relates to a ribbon guide assembly for a printer. A ribbon guide assembly (40) includes a ribbon guide (50) and a guide support (45). The ribbon guide (50) is employed on a replaceable printer ribbon cartridge to guide an exposed print section of a print ribbon (64) over a print head (80) of the printer. The ribbon guide (50) of the present invention has four members (56, 58, 60, 62) disposed between a bottom platform (52) and a top platform (54), whereby the members define a path for the print ribbon. The ribbon guide also has two collars (66, 68) coupled to the bottom platform and two of the members. Each of the collars defines a substantially circular opening. The guide support (45), affixed to the print head carriage, has two cylindrical alignment rods (90, 92) extending upward substantially perpendicular from the path of the carriage.
