Electrostatic printer

An electrostatic printer is a hard-copy output device which can produce graphics content. It uses dielectric-coated paper; a row of fine 'styli' electrostatically selectively charge the paper in spots as it moves past the row of styli. The process from there is much like xerographic machines: the paper then passes through a bath of 'toner' (extremely fine ink particles that form what is effectively a fluid), which adheres to the charged spots. The ink is then melted onto the paper by a heating element, often called a 'fuser'.
