Wicknix,
Thanks for the reply.
Unfortunately installing the CnM Printer.xap had no effect on CUPS at all

I know Davemoore was looking at the problem, and I just wondered if any progress had been made.
He seemed to think it was a permissions/privileges issue.
Also, still no luck with the web server on the LLL.
I have, previously, configured the LLL's IP address as a DMZ within the router, and port-forwarding. None of which work.
It's no biggy, just me playing around with things
