ABSTRACT:
A web drive mechanism to advance the print medium of a line or serial printer apparatus including a first stationary guide track for guiding the print medium along a defined path intermediate a medium supply position and a printing position, a platen about the printing position for receiving the medium, at least one rotor drive member having a rotor positioned adjacent to the guide track along the defined path intermediate the supply position and the platen with the outer peripheral surface of the rotor being adjacent to at least a portion of the arcuate path of the guide track to permit the print medium to travel intermediate the guide track and the rotor, the rotor drive member including a first medium gate for urging the print medium in engagement with the peripheral surface of the rotor as the medium advances intermediate the supply position and the platen, and a second medium gate for holding the print medium as it advances intermediate the platen and a medium take-up position, and a drive means engaging the rotor drive member for driving the rotor about its axis of rotation; whereby the rotor drive member drives the print medium from the medium supply position to feed it to the platen position and simultaneously drives the print medium from the platen position to feed it to the medium take-up position.
