I was following the setup instructions which clearly stated that i wasn't to connect the printer to my computer before i'd inserted the software disk. Only to connect it when prompted. Which i did, and then i hit problems.

I tried howie's suggestion last night of plugging it in the back first, and then it took me through a wizard to set my computer up. It was totally different to the setup instructions that came with my printer...

So, now it's all working fine. Thanks for all your help guys.
