Electrography, lonography, and MagnetographyElectrography, ionography, and magnetography are three other nonimpact printing technologies. They are younger technologies and are currently less prevalent in the marketplace than the electrophotographic, ink-jet and thermal technologies. However, they possess some advantages and could well become more important in the future.
