US Patent 7249838 Self threading wallpaper printer

A self threading printer is disclosed for producing rolls of wallpaper. It features a media loading area adapted to support a media cartridge in a position so that a media supply slot of the cartridge is closely adjacent to a pilot guide. The device's cabinet contains a media path which extends from the pilot guide to a printed media dispensing slot. A printhead is located across the media path and an internal processor accepts operator inputs which are used to configure the printer for producing a particular roll. A motor within the cabinet advances a media web out of the media cartridge and one or more other motors urge the media along the path and out of the dispensing slot.
