Abstract
A Direct Electrostatic Printer including a vacuum drum for transporting copy sheets past a plurality of DEP printhead structures for selectively printing various types of images. For example, black only images, highlight color images or process color images may be printed. To this end there are provided a plurality of printheads each utilizing a different color toner. Each printhead structure may be selectively actuated depending upon whether its color is to be used in forming the final image. Thus, where a process color image is to be formed, all of the printheads may be actuated and where black images are to be created only the black printhead is actuated.
