Abstract
A paper moving system for a computer driven printer/plotter comprises a paper pinching assembly positioned at the two oppositely facing edges of the paper adjacent the print zone 10. The edges of the paper are fed through each assembly where the paper is gripped between a lubricous shim plate 52 and a straight stretch of a paper drive belt 42 which frictionally engages the paper. The belts of each assembly are biased toward the shim plates by a spring urged rail 50 to hold the belts in non-slip engagement with the paper. The paper is tensioned edge to edge by the assemblies so that a paper table or platen underneath the print zone is unnecessary.
