It's been 9 months that everyone who runs the latest Windows 10 version has been unable to print PDFs integrated into Internet Explorer. The issue has now carried over into 20H2 unresolved and with no update from Adobe (or MS). This ONLY affects Reader, so it can't even be escalated with a support case.
Please provide an update, even if it's "lol we don't care about IE use case scenarios for Enterprise anymore" or "MS has no interest in working with us during a pandemic to fix this". Because I've got plenty of kiosks that require IE and printing the PDF within the browser where this situation is breaking entire operations workflows.
The insecure workaround is to uncheck the "Enable Protected Mode at startup" feature under Edit > Preferences > Security (Enhanced). The secure workaround, as my boss said, is to move to a different product.
