Abstract: Styluses (14) are scanned across the width of a roll of electrosensitive paper (10) and are selectively energized to vaporize small area on the paper's coating (13) to thereby form characters (26). When the coating vaporizes, a spark is produced which generates a broad band of electromagnetic energy which is conducted into the environment due to the conductive coating of the paper acting as an antenna. In the present system isolation bands (24) are produced by continuously energizing all styluses as they scan across the full width of the paper, thereby causing an entire band of the paper's conductive coating to be burned off across the entire width of the paper. Each isolation band severs the conductive surface of the paper, thereby reducing the effective length and/or propagation capability of the antenna created by the printed paper and lowering the level of radiated energy.
