Abstract
A method of printing on a print face of a linerless media with the printing face of a printhead without a platen member opposite the printing face. The method comprises the steps of, guiding the print face of the media to a point close adjacent and slightly above the printing face; routing the print face across the printing face; pulling the media across the printing face from a point slightly above the printing face; and, creating a drag force on the media to hold the print face against the printing face during printing. A guide member guides the media to a point close adjacent the printing face. The drag can be created by putting a drag clutch on the supply roll, routing the media between drag rollers, or having a high friction surface on the guide member.
