Abstract
A multipass, multicolor electrostatic plotter or printer has a continuous vacuum transport belt rotatable for substantially a complete revolution past a stationary writing head. The vacuum transport belt provides a vacuum to the entire contacting surface of a recording medium to stabilize and register the recording medium with a previously unattainable degree of invariance, thereby enabling information to be printed upon the recording medium simply by moving the transport belt with respect to a stationary electrostatic writing head disposed for contacting the recording medium across its entire width.
