Abstract
A printer controller system for controlling printing on media (e.g., a strip of labels) supporting a series of RFID transponders and for communicating detection of void RFID transponders to downstream devices. The printer controller system includes a void detection system for detecting void RFID transponders, a printing system for controlling printing to the media and a void communication system for communicating detection of the void RFID transponder to downstream devices. This allows the downstream device, such as a label peeler, to anticipate the void RFID transponder and deal with it accordingly. The printer controller may include a media advancement system that is configured to continue advancing the media and RFID transponders past the print head even when the RFID transponder is detected and avoid slowing the printing process. The printer controller system may be configured to submit void indicia to a print head and recommunicate a formatted image when a RFID transponder has been voided.
