DIFFERENTIAL FRICTION MEDIA DRIVE ABSTRACT OF THE DISCLOSURE 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 differ- ential 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 print- head (12) near the drive surface (16) allows for high qual- ity printing, and very small top and bottom margin dis- tances.
