Accessing Driver Settings from UI Plug-Ins

  • Article

Important

The modern print platform is Windows' preferred means of communicating with printers. We recommend that you use Microsoft's IPP inbox class driver, along with Print Support Apps (PSA), to customize the print experience in Windows 10 and 11 for printer device development.

For more information, see Modern print platform and the Print support app design guide.

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.
