Was told that a Kodak 5250 wireless printer cannot be hooked up to att uverse internet service?

This was told while trouble shooting with Kodak technician. Printer will not recognize att wireless.|||"AT%26amp;T Wireless" is the cell phone system, so that's obviously not going to work. But if the printer's manual says that it is a network printer and shows it connected to a router, there's no reason why the U-Verse residential gateway (modem-router) would not make it work. It does so with other network printers.
