ABSTRACT:
A method and apparatus for printing information on a web of material utilizing a roller platen located on the opposite side of a web feed path from a printhead. The roller platen has an outer arcuate surface which presses the printing material against the head and draws the material and a printing ribbon past the printhead in a printing operation. The roller platen has flattened surfaces on its circumference that facilitate feeding of the web of material between printing operations.
