Abstract
A paper feeding apparatus for feeding fanfold paper to a printer is provided. A cylindrical platen is rotatably mounted in the printer. A paper feeding tractor is provided upstream from the platen in a paper feeding direction. A power mechanism drives the platen and the paper feeding tractor. A pair of rollers is located above the platen downstream from the platen in the paper feeding direction. One of the rollers is coupled to the power mechanism causing it to rotate with a circumferential speed which is greater than or equal to the circumferential speed of the platen. A pressing member presses the fanfold paper which is fed out from the platen towards the rollers.
