1. A system comprising:

  • a printer assembly with a print media pathway configured to receive print media comprising a plurality of radio frequency storage devices arranged in at least two columns arrayed across a width and down a length of said print media;

    at least one controller;

    two or more radio frequency antennas; and

    at least one data programmer for transmitting radio frequency signals via said radio frequency antennas, the at least one data programmer being controlled by the at least one controller;

    wherein said radio frequency antennas are arranged into at least two groups of antennas along an axis perpendicular to a print media direction of travel, each group of antennas being in communication with the at least one data programmer and controlled by the at least one controller such that a first group of the antenna groups communicates with print media having radio frequency storage devices arranged in N columns across the width of the print media, and a second group of antennas communicates with print media having radio frequency storage devices arranged in M columns across the width of the print media, wherein N and M are each greater than one and not equal to each other.
