A cartridge for a dye-impregnated endless ribbon includes a transport device disposed within the cartridge; the transport device includes a driving member having a surface, and a stationary member having another surface so that the surfaces define a passage for the ribbon. Friction-generating devices are disposed near the surface of at least one member and in contact with the ribbon, causing the ribbon to move only in one direction through the passage. A drive device is provided and may be operated to move the driving member with respect to the stationary member.
