I want to create a login scripts on the Windows 2003/2008 Domain to stop users installing and using certain Printers. e.g HERCULES100 is a Windows 2003 Printer Server and HERCULES150 is a Windows 2008 Server and dont want my Citrix 2003 Users using HERCULES150 or vice a versa.

I know there is a Point and Policy in Group Policy but it isnt practical as a script.
