A compressible roller is mounted near the ribbon exit of a cartridge. As the ribbon vibrator mechanism moves the ribbon at the print area, the roller changes shape to neutralize vertical forces on the ribbon. The tendency for a ribbon to creep vertically is neutralized without linkage mechanisms to compensate for the movement of the ribbon vibrator.
