I'm trying to share a printer (canon mp730) through a wifi network. My computer (windows vista) is connected to the printer directly. The other computer is windows xp. When I'm working on the xp machine and press "print", it opens a dialog box and form there I select "find printer". When I click on that, it shows me the printer connected to the Vista machine select print, I get a warning message saying "you are about to install a printer driver on your machine...blah blah". I click "yes" on that and then get a message saying that the server for the printer does not have the correct printer driver installed. What to do? It seems like I've got the latest driver for the mp730 installed on both machines.
