How do I add a wireless Printer

I have XP on my network and a wireless printer. I was trying to use the wireless printer on windows 7.The xp and the printer show up on the xp machine but I cant seam to get them on the windows 7 machine.Windows 7. will scan but will not print.The printer or xp dose not show up on the windows 7 machine.

I have windows XP on a Sony laptop VGN-FS550.
A Kodak wireless Printer 5250.
