I am trying set up a small network at home and was thinking of using an airport express to hook up a older dell laptop running windows xp home. My plan was to hook the express to the second ethernet connection on my Mac Pro and share the connection with the hopes that the windows machine would be able to print over wireless to my usb printer I plan hook up to the airport express. Is this possible or am I asking way too much? I have read through the product description and it sounds like it should work but the notes can get confusing, for example it says that windows xp should print over wireless but a later note says you must have OS 10.2 or greater. Is that just for a mac trying to print or is that for any machine printing? Last in this long line can anyone tell me which model numbers are which. I have been looking on ebay but I can't find out which model numbers are new and which are old. Thanks
