Disabling Redirected Printers on printserver 2008 R2

I noticed when i logged on to my printserver using RDP there were a lot of printers coming up. Showed up as (redirected 3). I know i can disable it on the client but then all the system administrators should do that everytime when they log on to the print server. You can disable it on the server itself. The best way to do this is to make a GPO and set the following setting : Enabled

If you want to do it the wrong way, you can use GPEDIT.msc

Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Printer Redirection > Do not allow client printer redirection
