Data projector with printhead

摘要

A data projector includes projector control circuitry for receiving analogue data signals from a computer-based machine representing images to be projected at a viewing surface. An analogue to digital converter is connected to the control circuitry for receiving the analogue data signals from the control circuitry and for converting said signals into digital signals. A printhead prints images represented by the digital signals. Printer control circuitry controls operation of the printhead and delivery of data to the printhead.
