Abstract
A printer assembly that can handle media of different width and thicknesses has a pivotable platen with a lower body portion and a curved upper portion which extends from the lower portion. The curved portion is pivoted forward to contact the carrier material. A wound torsion spring, with one end held against a stop and the other end free to move the platen, is utilized to urge the platen in a forward direction to contact the carrier strip. The spring pressure is sufficient to keep the platen from being moved by the force of printing elements striking the material to be printed on. The assembly is also provided with spring-mounted edge guides for handling different widths of printing media to be fed through the printer assembly.
