We are moving to Group Policy for deployment of printers. The environment is a mix of mostly Ricoh with some Lexmark, HP and Brother still left around the place.
All other printers have been fine deploying bar the Brothers. Even just directly installing one of the Brother printers on a Windows 7 client gives a UAC prompt. All other manufacturers do not give a UAC prompt on installation.
We have the following policies configured and in effect on the client (which are obviously allowing the other manufacturers to install fine):
Computer Configuration\Policies\Windows Settings\Local Policies\Security Options\Devices: Prevent users from installing printer drivers : Disabled
Computer Configuration\Policies\Administrative Templates\Printers\Point and Print Restrictions : Disabled
Computer Configuration\Policies\Administrative Templates\System\Driver Installation\Allow non-administrators to install drivers for these device setup classes :
{4658ee7e-f050-11d1-b6bd-00c04fa372a7}
{4d36e979-e325-11ce-bfc1-08002be10318}
User Configuration\Policies\Administrative Templates\Control Panel\Point and Print Restrictions : Disabled
I have confirmed within one of the Brother printer driver INFs we have tried that the GUID matches as above in the allowed list just in case.
Our print server is 2012 R2. Speaking with Brother they advised this is not supported by the device I mentioned as one of the affected. As a test I installed their recommended driver on 2008 R2 with the same result of UAC prompt on installation.
Here is the UAC prompt:
Simple as what am I missing?
Brother claimed when they test within a Domain environment they do not receive this, but when we try on multiple models, whether the Brother recommended PCL, their universal driver or the "Found Printer Wizard" driver we get the same result only with Brother printers.
Some of the Brother models:
MFC-8880DC
MFC-J6710DW
HL-3075CW
MFC-7460DN
