Well, my state tax returns printed today....Yeah.
I followed the recommendation on the original thread to look at the reports within the CONSOLE app. I saw that the system was calling a "Gjallarhorn" process located in /Library/Application Support/Avira/Gjallalrhorn.app/Contents/MacOS/Gjallarhorn. I erased that file.
Avira is antivirus software I installed a couple of years ago. I thought that all its files had been removed when I did a full re-install of macOS in November 2018. Note: I did not have any issue printing 2018 state tax returns during tax season this time last year.
I searched "AVIRA" within FINDER, and I found two DAEMON files. I erased these files.
Thank you to those who contributed suggestions to this thread.
Stay healthy!
