A long-life inking cassette is provided wherein an inkable ribbon is pumped into a ribbon storage zone by a pair of textured nip rollers. The ribbon is drawn from storage, rotated 180. degree. , re-inked, and passed at an angle and under tension past a print head before being returned to the nip rollers. A pair of dams are positioned to contact opposed edges of the ribbon as the ribbon leaves the storage zone to prevent folds of the ink ribbon from passing outwardly from the storage zone. Means are provided to amplify the drag on the ribbon between a dispensing pin at the outlet of the storage zone and an end of a first leg of the cassette. The drag amplification causes the ribbon to be taut when drawn past the printhead.
