Thanks to you guys I now have a very basic working server.
One thing is still bothering me
When I print to my HP OfficeJet 710 my server (Fedora FC2) everything is ok colour and all.
When I print from any of the PCs connected to my server (all windows) the print is only in B&W.
If I connect the PC to the printer direct all is ok.
One other small matter. When I setup the network printer on my last PC it seemed to want to download drivers from my server which it couldn't. What is happening here? I ended up using a CD I have....
