A re-inkable ribbon cartridge (11) for use in a printing device for printing on a sheet of paper and obtaining a consistent darkness of print. The ribbon cartridge (11) has a base member (19) with an exit arm (15) and an entrance arm (17) extending from the base member (19) with a print space between ends of the arms. A ribbon storage chamber (23) is formed in the base member (19), an ink ribbon (25) extends from the ribbon storage chamber (23), through the exit arm (15), the print space (21), and the entrance arm (17) to return to the ribbon storage chamber (23). A drive wheel (27) is mounted in the cartridge for moving the ribbon (25) out of the storage chamber (23) with a press wheel (29) that presses the ribbon (25) against the drive wheel (27) and meters ink onto the ribbon (25). An ink reservoir chamber (31) is formed in the cartridge, and a foam pad (33) containing ink is positioned in the ink reservoir chamber (31). A wick (35) extends from the foam pad (33) and contacts the press wheel (29) to transfer ink by capillary action from the foam pad (33) to the press wheel (29) which meters the ink onto the ribbon (25). A spring (37) presses the wick (35) against the press wheel (29).
