Abstract
A network printing system is provided for allowing a single channel connection to support multiple channel connections when implemented over a direct connect, non-network device. More particularly, a socket simulation protocol (SSP) is incorporated into the printing system for providing multiple data paths for allowing serial based host drivers to interact with the network printer in the same synchronous model as in multiple connection based drivers. SSP enables a normalized interface to the printing system so that various heterogeneous network services protocol/ports may interact in the same way and for also enabling new protocol/ports to be easily extended and integrated into the network printing system.
