Printing not working with RDP

I have a Windows 2008 R2 server that was a standalone server, that users were using RDP  and printing. We updated the server with AD services, DNS and DHCP, now when user RDP in and try and print, I see the job go in and out of the print queue for that printer, but nothing prints on their local printer. I enabled "Use Remote Desktop Easy Print Printer Driver first" in the Domain GPO, but still the same result. How could I troubleshoot this further?
