Accessing Driver Settings from UI Plug-Ins

A UI plug-in can obtain the current status of printer features and other internal information. The IPrintOemDriverUI::DrvGetDriverSetting COM interface method is implemented within the printer interface DLL for Microsoft's printer drivers and can be called by UI plug-ins.

Additionally, the following methods allow UI plug-ins to modify driver information:

IPrintOemDriverUI::DrvUpdateUISetting allows a UI plug-in to notify the driver when a user has modified driver settings.

IPrintOemDriverUI::DrvUpgradeRegistrySetting allows a UI plug-in to modify device settings in the registry, so that registry settings used by older driver versions can be updated.
