Abstract
An improved printer and method of printing uses an electrostatic field at the point of ink contact with the print medium to improve ink application. This improved printer and printing method makes possible a higher resolution final image; provides for greater control of the application of ink on the print medium; permits the use of a wider range of inks having variable viscosities, surface tensions, and elasticities; and permits the use of a variety of ink application speeds.
