Abstract

Media rolls, support structures for the media rolls, and media processing systems are provided. A media roll may include an identification transponder having retrievable information regarding the media units and associated media unit transponders wound around a core of the media roll. A support structure may include a spindle for supporting a media roll and include an identification coupler for communicating with the identification transponder. In addition to the spindle having the identification coupler, the media processing systems may include a second coupler for encoding the media unit transponders and a printhead for printing indicia onto the media units. The information retrieved from the identification transponder may be used to adjust one or more encoding and/or printing settings of the systems.

Claims
