So it seems another change in the March 2016 patch is is that you can no longer display the iPrint URL in an iFrame anymore:


Cannot be displayed in an iFrame. You get a blank page.
Changing to https has no effect.

Displaying separately (ie, using an href or something to launch a new window) works.

Have no idea what would change in the code that would prevent this.

We use this a lot in our Portal (https), and there's links that the users can click on for their own office/region to bring up the printer list so they can install printers.
If you use IE, you get this:

To help protect the security of information you enter into this website, the publisher of this content does not allow it to be displayed in a frame.
Have no idea why Novell/MF would do this (quite odd), even if you're referencing an https link.
Makes no sense to me.
