Adobe Reader DC does not print.

Adobe Reader DC does not print black.  I have version 2019.021.20061. I have a Windows 10 machine printing to a Canon MX922 printer.  I have no problems printing from other applications. I checked for updates and mine is current.

When I send a document to print, it looks fine onscreen, but only a few colors (a logo) print.  No black at all, either in the original or when I fill & sign.  This happens with all PDFs.
