Abstract
A method and apparatus relating to a unique printhead configuration is disclosed. The printhead configuration is based on a coplanar arrangement of two sets of electrodes. The electrodes are electrically separated from each other by a dielectric layer, and together create a matrix of charge generating sites. Such a printhead has a very low internal capacitance and therefore is suitable for high speed and high resolution printing.
