Printing system with a function of printing on labels

Abstract

A label separating system for separating labels from a backing web after the labels have been printed is disclosed. This system utilizes the paper holding roller which is used for holding paper against the platen as it is printed and a separating roller upstream from the paper holding roller. A tractor feed upstream of the separating roller draws the backing web from the platen over the separating roller. A holding member is positioned to limit movement of the paper holding roller as the backing web is placed under tension by the tractor feed, thereby insuring that the backing web disposed between the platen and the separating roller is urged toward a line connecting the center of the platen and the center of the separating roller. This insures that the backing web is bent to a sufficient degree as it passes over the separating roller to cause separation of the label. The holding member for holding the paper holding roller can be mounted on a pivoted lever that also serves as a part of a detachable mounting system for mounting the label separator on the printer. A guide roller is positioned adjacent and parallel to the separating roller and, with the separating roller, defines an S-shaped path for the backing web which further insures separation of the label from the backing web.
