A data processing system comprising a single Host coupled by a communications channel to a single multifunction peripheral is disclosed. The multifunction peripheral comprises a paper tray, a display, a user input device, a processor, a first memory for long term storage and a second rewritable memory for short term storage, a communications interface, the multifunction peripheral for providing document scanning and hard output functions. The Host comprises a processor, a first rewritable memory for long term storage and a second rewritable memory for short term storage, a communications interface, and a network adapter for communicating with a computer network. The communications channel coupling the communications interface of the multifunction peripheral and the communications interface of the Host. Data is transferred efficiently between the Host and the multifunction peripheral using the SCSI-2 standard by combining a header and content into a single packet and transmitting the packet using a SEND MESSAGE or GET MESSAGE command.
