Windows 8.1 provides a common framework to support PIN printing (a.k.a. secure printing) in-box.
Two primary goals are accomplished with this functionality.
Users are presented with a universal easily discoverable UI.
IHV's will no longer have to implement proprietary UI solutions.
This feature is available for IHV's implementing v4 or v3 drivers. The PIN printing standard UI is available in both desktop print-preferences dialogs and the modern print dialog.
