What are the networking requirements for AirPrint?
AirPrint only works with AirPrint compatible printers, unless you have special software to connect to the printer running on a machine the printer is locally connected to. A great solution for a work environment is the xPrintServer. It's a network adapter that attaches via ethernet to your network and is supposed to make any printer on the network it's attached to AirPrint compatible. It's available for preorder now. I'd partner with your network administrator to see if this is something that is right for your workplace.
