Tip: Use Group Policy Preferences to deploy printers to terminal server clients
We were just implementing some thin clients and were looking at ways to deploy printers using GPP when we discovered item level targeting in GPP which is designed for RDC/RDS sessions so I thought I would pass it on.
If you use loopback policies and then add a printer using the preferences section of group policy in the item level targeting you will have a section called "Terminal Session"
This will allow you to filter using thin client clientname (aka %clientname% in scripts) which allows you to target the printer to a specific terminal.
NOTE: this only works in user context not as a computer config in GP.
Other things you can filter with are things such as Application, initial program, session name etc which allows a lot of configuration for thin client setups all without touching a script. The filters can be used in other sections of GPP as well so its not just limited to printers.
UPDATE: There is a known issue with this targeting in 2008 R2 where it basically doesn't work. To fix please install http://support.microsoft.com/kb/981054
