GPO not allowing setting default printer

We have created a GPO that locks down a shared, kiosk-type PC.  We do not want users to be able to access Control Panels, but we do need to allow users to set their own default printer.  Originally, we had a GPO setting:  User-Policy-Administrative template-Control Panel - prohibit access to control panel.  Obviously, that blocked access for the user to set a default printer.   So, the policy setting was changed to:  User-Policy-Administrative template-Control Panel - Show only specified Control Panel Items:  Microsoft.DevicesandPrinters.  
Users are still not able to set a default printer.  The default printer will vary based on the computer location, so we cannot set a default printer in the GPO.  Not sure how to resolve this.  Any help is appreciated.
