Well I am not sure what your wireless network is there, but mine is service by a Snow Airport Base Station. What happens here is that my powerbook or other macs that all have Airport cards
talk to the ABS and the ABS talks to the Airport Express which is ethered to the printer and that is how it works for me. The Airport Express just plugs into a 110 outlet and your printer is conected to the Airport Express by ether. The Express is a nice item. I take it with when I go on the road too and use it as a base station. It also will work with itunes to send your music wirelessly to any speaker system. I guess the Airport Express is like a print server but much more. Check out the Apple site. I am not the best source for answers but it works very well for me and I would very much suggest it for anyone. If you don't have an Airport BASE station as your access point now, I don't know if you can use the Express or not. It might work with any wireless router, not sure? You will have to ck the details out. Again go to the Apple Store and read up on the Express, Good reviews too! Good luck ,,,,,,,werp,,,oh it is only $69.00 for the refurb on Apple.com
