I can't get the Airport Express to work with this printer. The Dell 1700n laser printer is network ready, so it has both a USB port and an ethernet port. Ethernet is usually very easy to set up. I just plug it into my other router and it works. With the Airport Express, the orange light blinks forever. With USB, Bonjour sees the printer and appears to set it up properly, but the test page doesn't print (I'm using Windows XP). Anything I should be aware of to make the printer work with Airport Express, either through USB or ethernet?
