R6200v2, wired Windows XP and a Dell 968w Printer

OK have the router setup and running. Does an excellant job supportin all my wireless Windows 7 computers, external back up and printing, cell phones you name. Extremely happy with the product, HOWEVER, I have an older Windows XP system that connects to the router via ethernet cable and now it wont print to my Dell 968w AIO printer that is connected to the USB connection running readyshare printer. I've uninstalled the printer on the xp box and reinstalled several times and actually did see the printer showup in the Netgear USB control center only to disappear never to be seen again. HELP
