Windows 7 standard user printer installation

I am configuring Windows 7 for enterprise environment and issue working with right now is that we want to allow standard(non-admin) users to install local and network printers. I have defined following group policies settings in order to allow this:
•Computer Configuration/Policies/Administrative Templates/Printers/Point and Print Restrictions
 •User Configuration/Policies/Administrative Templates/Control Panel/Printers/Point and Print Restrictions
Both are set to Enable and Security Prompts, When Installing Drivers for a new connection = Do not show warning or elevation prompt.

Also I have defined a puch of Device class IDs to setting "Allow non-administrators to install drivers for these devices setup classes on
Computer Configuration\Policies\Administrative Templates\System\Driver Installation

After these settings I am able to add HP printers using Hp universal drivers and also Xerox Multifunction devices with universal driver without elevation promt, but Xerox mfp with model specific driver is not installed without admin account. Any ideas what still should be done in order to have this working? The list of Setup Class IDs already added are shown on the pictureSetup class IDs
