Last week Microsoft pushed updates, KB4021558, KB 4022719, KB 4022725 and KB4022727 to Internet Explorer that seems to have broken its printing functionality that many users are used to using. In other words, when you open a document, such as a PDF, in an Explorer browser window and hit the print icon from there, it no longer prints properly.
Most reports indicate that users can still go as far as clicking the “print” button in Explorer, but the printer will spit out a blank page as a result. We were able to undo this update by doing a system restore to a previous date.
For now, the best workaround (other than restoring) is to open the files in another file viewer, like Adobe Acrobat or by switching browsers. Microsoft has not done anything to suggest that a fix will be applied in future updates, and this may coincide with a larger push for Edge browser adoption.
In the meantime, advise your end users to avoid using Internet Explorer for file viewing and printing.
