ABSTRACT:
A printer including a first and a second guide shaft which extend parallel to an elongate platen, to slidably support a carriage on which a print head is mounted. The second guide shaft is spaced by a greater distance away from the platen than the first guide shaft. An active length of a print ribbon is exposed outside a container of a ribbon cassette. A ribbon guide is supported by the second guide shaft pivotally about an axis of the second guide shaft, for supporting the active length of the ribbon so as to pass between the platen and the print head. The ribbon guide is pivoted by drive means, so that the active length of the print ribbon is moved relative to the print head and the platen, in a direction perpendicular to a longitudinal direction of the platen.
