A credit card imprinter has a flat imprinter base on which a merchant plate, a credit card and a form set are positioned. A hand operated carriage is pulled back-and-forth over the form set and imprints the merchant plate, in one direction, and the credit card, in the opposite direction, on the form set. The carriage contains two independent platen rollers each rotatably mounted on a separate axle. The axles and their rollers are urged upwards by springs and are automatically shifted from an upward idle position to a downward print position by a unitary one-piece plastic slider. The slider has four outwardly extending arm portions which act on the axles to shift their heights.
