Printer connection problems

I am trying to connect a printer (Dell 968 AIO) using bonjour on airport express, I am running windows vista home premium, I have connected the printer directly to laptop and this has worked on the system, but on occasions does have an error of 'unable to communicate' when I do plug the USB in to the airport and run bonjour it states that there is no bonjour printer available, I've turned off windows firewall, but still no joy, I do have Norton protection running, can anyone help????? PLEASE.

I'm not quite sure what it is that you're using, as I've never used it myself. But check the following.

Start> Right Click Computer> Manage> Services and Applications>Services

Make the following set to Automatic Start Up Type (Double click or right-click then properties)

Printer Spooler
Plug and Play


Good Luck
