An RFID label with embedded tag is passed through an RFID antenna in a
printer system, where the RFID antenna allows a roll of such labels to
pass in close proximity to the antenna and still allow each individual
RFID tag to be read and/or programmed. The RFID antenna has a rectangular
RF field spreader in contact with a triangular divergent RF conductor
with an RF source point at the point. Ground planes are located on either
side of the antenna. In another embodiment, the printer system extracts
or parses bar code commands from a data stream and passes the commands to
both a printer and an RFID reader to print the image and program the tag
with the bar code information.
