ABSTRACT:
A copier for rendering an image of an object onto a physical medium includes a scanner, a printer and an external processor. The scanner and the printer are coupled to the external processor by a high-speed serial bus having a latency and a maximum signal transmission rate sufficient to enable transmission to the external processor of digital image signals generated by the scanner which represent the image of the object without prior interim storage of the digital image signals in a buffer on board the scanner. The high-speed serial bus further has a latency and a maximum signal transmission rate sufficient to enable transmission of the digital image signals from the external processor to the printer for rendering the digital image signals onto the physical medium without prior interim storage of the digital image signals in a buffer on board the printer. In an embodiment, the external processor is capable of processing the digital image signals and the scanner is capable of transmitting the digital image signals without prior on-board digital processing of the digital image signals in the scanner and the printer is capable of rendering the digital image signals without prior on-board digital processing of the digital image signals in the printer.
