IE11 Windows 7 Print issue after kb4021558

Since this update we have had numerous calls regarding printing from our web app.  Our web app uses an iframe and we use css @media print to hide all but this iframe for printing purposes.  Since the update the user receives an Error 404--Not Found instead of the actual page.  It would seem from the network trace that IE creates a temp .htm file in the local directory like D3CD911.htm, it then downloads css/js resources and then finally it makes this call /D3CD911.htm.  This is making a call to  This obviously does not exist on the website so the 404 is returned.

I struggling to find a pattern to the problem and it doesn't seem to be affecting other public sites.

Any guidance would be much appreciated.

Thanks.  Also I have found if you use javascript window.print() it has the same issue.  However using document.execCommand('print', false, null) works
