1. An electric paper printer comprising:
a two dimensional array of electric paper printing elements, each electrical paper printing element to output an electrical
characteristic, the electric characteristic to set the color of a pixel on a sheet of electric paper;
an apparatus to create a relative motion at the time of marking between a sheet of electric paper and printing elements marking
the electric paper; and,
circuitry to adjust the electrical characteristics of the two dimensional array of electric paper printer elements such that
a particular electrical write characteristic approximately tracks a corresponding pixel of the electric paper for a duration
of time that the corresponding pixel remains approximately adjacent the two dimensional array of electric paper printer elements.
