Wireless network for HP M15w Wireless

HP Recommended
LaserJet Pro M15w
macOS 10.15 Catalina

LaserJet Pro M15w worked flawlessly on wireless network yesterday.  Today, printer would not work.  Upon attempting to reinstall through HP Smart, the printer was not installed.  Then, when I attempted to install by adding at the Printers & Scanners in system Preferences error message appeared:  "fax.backend" will damage your computer.  Installation would not complete.  Had to settle for USB connection, but because printer didn't install wirelessly, AirPrint function is not available for iPhone & iPad.  I am wondering whether this is related to HP's unannounced revocation of certain security-related certificates, which has impacted other HP printers such as the LaserJet P2015d.
