Even disabled my virus protection using ms config and still have same problem. It happens on many websites but not all of them. Actual results: Does not print correctly, does not print preview correctly, does not print to PDF correctly. It only does 3 pages and they show up wrong and missing lots of info. Expected results: The site should print correctly and show up in print preview correctly it should also show whole page/site when printed.
