nowadays linux in general is pretty good for adding printers without having to install drivers and then pretty much shares your printers on the network and pop up automatically on the clients. usually my ubunto boxes just show the printer but the other day for some reason it never, anyway a quick fix is at hand
on the computer with the printer attached to it in a broswer input 127.0.0.1:631
which is local host administraton screen for the cups printing system
now we want administration and section which is the second tab at the top
then just check the boxes on the right as shown on picture
Or as required of course!
this will restart the printing system and if you have a ubunti client by the time you get back in to the system settings and preferences the printer will probably already be showing ready and installed without having to do a thing! if not just click and browse and select the network printer to install
the username and password it will ask for will have to be a user name with admin privileges to add printers.
