How to AirPrint to a printer that does not have WiFi? My mother has a Samsung printer that works perfectly fine... except that it's not network enabled (it doesn't have WiFi). She wants to print to it using her iPad. Is there any way to do this?

(The most obvious way would be to look for a AirPrint enabled print server, but as odd as it sounds, I haven't been able to find one anywhere. Does such a thing exist?)
The retired Apple Airport Express is an AirPrint server and they can be found for around $50 used on eBay. Add the Airport Express to your home network as a wifi extender or second access point and it'll broadcast the printer availability on iOS devices connected to the network.
