Abstract (en)
An apparatus for providing motive force to a medium (14), including a high friction drive surface (16) and a drive plate (20) which is surfaced with an extremely low friction material (30) is provided. The friction differential produced by the surface variations is sufficient to furnish superior transfer of motive force and to avoid problems of jamming and mishandling. Placement of a printhead (12) near the drive surface (16) allows for high quality printing, and very small top and bottom margin distances.
