"Wake up the printer" by power-cycling it; Windows may not initially see it if it is in power-save mode. Confirm on your router's configuration screen(s) that it has been assigned an IP address. Then have Windows 7 look for a network printer.
Thanks, the wake-up didn't work but the having Windows search for the network printer did and it reinstalled the driver. Now I have the icon I wanted although it still puzzles me why the printer was working wirelessly without the icon showing. Appreciate the help
