Abstract
A thermal printer is provided which is adapted for printing information onto multiple types of print media, including both a conventional print media and a linerless print media. The thermal printer comprises a mechanism that transports the print media through a print region of the printer, which comprises a thermal print head and a rotatable platen disposed such that the print media is transported therebetween. A coating is provided on selected portions of the transporting mechanism and the platen. The coating comprises an epoxy resin mixed with a powder to provide a textured surface. The powder of the coating further comprises at least one of titanium dioxide, silica, and calcium sulfate. The coating has a film thickness ranging from approximately 2.5 to 3.5 mils. The textured surface provides sufficient friction and non-stick characteristics to permit the printer to effectively transport both conventional print media and linerless print media.
