Abstract

A thermal printer prints linerless labels in such a way that printer components will not stick to the adhesive face of linerless labels. Substantially stationary printer components, such as a label guide, transport plate, front panel, and stripper blade, preferably have the adhesive face engaging surfaces thereof plasma coated so that adhesive will not stick to them. An optional cutter provided downstream of the stripper blade also has plasma coated surfaces. A driven platen roller has a surface thereof coated with or covered by a high release silicone, which will not stick to the adhesive, but has high friction characteristics to facilitate drive of the labels. In a direct thermal printer, a plasma coated tear off surface is downstream of the driven platen roller, and stripper belts, a second roller with O-rings, and the like are provided to prevent the labels from wrapping around the driven platen roller. One or more sensors may also be provided for controlling drive of the platen roller in response to the position of registration marks on the linerless labels.
