Now I have a printer set up on the network, any one of us can print to it, and I don't have to leave the PC with the printer attached switched on anymore, the printer is now plugged into the Livebox.
It's not rocket science, but Orange will want to launch it fully tested, and I don't want to wait.
Thanks to the people on the other forum, it's not one I've seen before.
