PDF printer freezing with Microsoft Office 2016

We have four computers running Microsoft Office 365 on monthly subscription.  On two of them we used, a few days ago, Microsoft Word and Microsoft Publisher to print PDF's using the PDF driver.  On the same day we found that on both computers we could no longer print a PDF file using either Microsoft Word or Microsoft Publisher.  The print driver dialogue box displays, the speedometer ribbon goes halfway, and it freezes.  Both computers use Windows 8.1.  Both use Adobe CS6 Design Suite.

The third computer using Microsoft Office and Acrobat DC from the cloud seems to have no problems.

Anyone have any ideas of WHAT happened and HOW to FIX the situation.

Thanks in advance.
