notifyName

Set the print job notification name.
[read/write property] notifyName([out, retval] BSTR *notify) notifyName([in] BSTR notify)
This property sets the print job notification name. This sets the pNotifyName in the JOB_INFO_2 structure, which "specifies the name of the user who should be notified when the job has been printed or when an error occurs while printing the job".

resetParams resets this to its default value, which is unset.

VB:
pdf.notifyName = "fred"
