Abstract
A toner jet printer and method of use for printing images by manipulating individual toner particles using two-dimensional print cell arrays built by micro electro mechanical systems (MEMS) technologies. Toner particles are positioned by electrostatic forces within each print cell by either selective or non-selective filling. If selectively filled, each cell is then subjected to a mechanical force to eject the toner particles onto a paper substrate. If non-selectively filled, only those print cells corresponding to an intended image are addressed electronically to eject a toner particle from an addressed cell by mechanical forces controlled by micro actuator actuation. Single color or multiple color printing can be achieved using the same cell array.
