Abstract
A network multifunction peripheral server permits simultaneous processing of print and scan jobs from one or more networked clients. The server of the invention connects to a network through a network interface unit, preferably capable of communication via a plurality of predetermined network protocols. It includes one or more ports for connection to a multifunction peripheral through a communication link. Separate print and scan data flows are established for each port by the server. The server also establishes separate logical channels to the port through a protocol which allows multiple logical channels per communication link. Print and scan jobs are handled simultaneously for a single multifunction peripheral through separate print and scan data channels logically established by the server.
