Abstract
Direct writing method and apparatus and methods for imaging charged toner particles directly to a print receiving medium. The charged toner particles are imaged directly to a print receiving medium using one electronic writing head for each color. The writing heads employ voltage traveling waves to convey toner in the form of toner packets to toner transport channels. The size of the toner packets is controlled by using additive or subtractive methods to perform imaging.
