To follow up on teh previous post, this was our solution as well, but I had found a little bit more info. The following can be set locally within the image or using GP:
• There are TWO "Point and Print Restrictions" settings
• Computer Configuration/Policies/Administrative Templates/Printers/Point and Print Restrictions
• User Configuration/Policies/Administrative Templates/Control Panel/Printers/Point and Print Restrictions
Of these two, the one under Computer Configuration seems to be the important one. But the original Server 2008 doesn't include this setting in the list -- you need Server 2008R2 for this setting to show up. If you download the administrative templates from Server 2008 R2, extract, and copy the PolicyDefinitions folder to C:\Windows\sysvol\domain\Policies\PolicyDefinitions, this missing policy will show up magically in Group Policy Management Editor. Of course, the ADMX files from Server 2008 R2 causes Group Policy Management Editor from Server 2008 tocomplain about parse errors, but it works just fine to click "OK".
Once you've installed the proper ADMX files, for this to work in Windows 7, configure both of these "Point and Print Restrictions" settings to:
• Enabled
• Security Prompts, When Installing Drivers for a new connection = Do not show warning or elevation prompt
• Security Prompts, When Installing Drivers for a new connection = Do not show warning or elevation prompt
Also, don't forget to make sure the users have permission to install printer drivers, since you're not even going to try to use Admin privileges any more:
• Computer Configuration\Policies\Administrative Templates\System\Driver Installation
• The setting is called "Allow non-administrators to install drivers for these devices setup classes".
• You will need to add the device class GUID of printers: {4d36e979-e325-11ce-bfc1-08002be10318}
Don't forget to update the computer policy on the workstation by running "gpupdate /force".
