Abstract
A point of sale printer includes a paper supply mechanism rotatably mounting a paper supply roll within a frame through a resiliently mounted bearing member extending into each end of a central hole in the roll. The frame is manually pivoted between an open position, in which the roll is installed and removed by moving the bearing members outward with movement of the roll, and a closed position, in which the roll is rotatably held in place, with outward movement of the bearing members being prevented by stops within the printer. With the frame in its closed position, a paper web is pulled from the roll for printing. An alternate configuration allows the printer to use a narrow paper roll.
