1. A machine for reproducing the visual image on documents onto a paper substrate comprising:

  • support means;

    display means carried by said support means for selectively displaying said document;

    camera means for scanning said document and for converting the visual image on said document onto a corresponding electrical video signal;

    imaging means for selectively exposing said visual image on said document to said camera means;

    a cathode ray printing tube means having a wire matrix;

    circuit means electrically connecting said camera means to said cathode ray tube means to cause said wire matrix to be electrically charged in a pattern corresponding to the visual image exposed to said camera means; and

    , including means for reversing the electrical image produced by said camera means;

    transport means for selectively moving the paper substrate by and closely adjacent to said wire matrix at a rate corresponding to the exposure rate of the visual image to said camera means; and

    developing means for converting said electrically charged image imposed on said paper substrate into a visual image including a member for positively forcing said paper substrate across said wire matrix at a rate corresponding to the exposure rate of the visual image to said camera means, toner particles, and means for applying said toner particles to the electrically charged image imposed on said paper substrate on that side of said paper substrate opposite said wire matrix.
