Abstract
A network printing system for enhancing two-way communication between host computers and printers connected to a network. More particularly, the network printing system provides an imaging device protocol (DP) which enables various network service protocol/ports for host computers to communicate with the printer by "seamless plug and play" connectivity. IDP operates independently of the network layers below and only requires that the transport protocol/port be bidirectional. IDP allows all of the incoming print job information to be placed in the print queue regardless of the protocol for a wide variety of heterogenous network protocols. As a result, the network printing system enables print jobs from host computers connected to the network by a wide variety of heterogenous network protocols to be fairly arbitrated at the printer.
