After installing KB4022715 (Win10 1607) or KB4022725 (Win10 1703) or KB4022719 (Win7) (released by Microsoft on 6/13/17), which brings Internet Explorer to 11.0.043, CRM 2011 and Dynamics 365 (2016) users receive a "404- File or directory not found" when attempting to PRINT a Record (Contact, Report, etc.) to a physical printer or to a PDF. The Print Preview window DOES properly show what will be printed – but the physical printout or PDF will show “404 – File or directory not found.”

Uninstalling the Updates listed above, which rolls Internet Explorer back to the previously installed version, immediately resolves the issue.
This is not a good solution as the above mentioned Updates contain fixes for many other things – beyond just updating Internet Explorer.
