PDF Reader Won't Print Post Window 10 Anniversary Update

PDF printing worked O.K with Windows 10 pre August 2016 major update. Now it seems  to print, goes through printing bargraphs, but no document is entered into the print buffer. I checked previous postings on the Adobe forum, made sure reader was latest version, even tried to use the "Print as Image" route, but "Print as Image" click was greyed out and I could not enable it. No Joy!!
