ABSTRACT:
The present invention is a guide for use in combination with a printer which includes a frame and a print head that is mechanically coupled to the frame and that is adapted to travel laterally along the front of the frame. The printer also includes a platen which is mechanically coupled to the frame and which is disposed so that a print medium may travel between the platen and the print head, and a pair of sprockets, each of which has a cylindrical sidewall on which the print medium travels. Each of the sprockets has a disc-shaped hub and is axially coupled to the frame. The media guide includes a pair of integral members each of which is disposed adjacent to one of the sprockets so that the print medium is disposed between the cylindrical sidewall of the sprocket and has a first portion which is mechanically coupled to the disc-shaped hub of the sprocket adjacent to a second portion of the integral member so that each of the sprockets may rotate independently of each of the integral members. Each of the integral members has a pair of fingers which are mechanically coupled to the disc-shaped hub of each of the sprockets and is biased by a spring which resiliently couples the pair of fingers.
