Abstract
A mono color ink ribbon is held by a pivotable ribbon holder in front of a print head being moved along the platen, and the ribbon holder rides on a rail which has a raised center or central portion and lower ends, so that on a pass by the print head from one end to the other, the ribbon holder is moved up and down over a full cycle. This way, full use is made of the ribbon which is run in a Moebius loop in a cartridge.
