Diagnosing socket "Connection reset by peer"

[loial]

I have a sockets client that is connecting to a printer and occassionally getting the error "104 Connection reset by peer"

I have not been able to diagnose what is causing this. Is there any additional traceing I can do(either within my python code or on the network) to establish what is causing this error?

Currently I am simply trapping socket.erruor 

Python version is 2.6
