PrintAsyncNotifyError	Specifies the error code portion of the HRESULT returned after an asynchronous notification failure.
PrintAsyncNotifyUserFilter	Specifies whether notifications will go only to listening applications that are associated with the same user as the Print Spooler-hosted sender, or go to a broader set of listening applications.
