2009 MacPro running Mojave won't print from any app: spinning beachball

2009 MacPro running 10.14.6 needed for about 6 more months. Recently, it has started refusing to print from any application (Acrobat, Word, Excel, QuickBooks 2016.) Everything is normal until I try to print. Then, a spinning beachball that won't stop. Force Quit works sometimes ("Not Responding") but sometimes does not and I have to do a hard restart.

Usually, restarting fixes the problem, but sometimes has to be repeated several times before I can print again. I have deleted and reinstalled the two printers I use and made sure that all printer software and firmware is updated as much as possible for Mojave.

The computer is set to not shut down and to restart early each morning. Other than the printing problem, all is working normally.

I can provide an EtreCheck file if it would be helpful.

Any other suggestions?

Thanks.

Mac Pro, macOS 10.14

... and assuming that's the case, it suggests an inability for the app to summon the standard macOS print dialog. I think reinstalling macOS is justified.

Try "Safe Mode" before you do that: Start up your Mac in safe mode - Apple Support. Assuming macOS is working properly you ought to be able to print in Safe Mode.

OK, back at the office and just ran an EtreCheck report. I just noticed that one of my 4 internal hard drives (an older 4 TB drive that I use for Carbon Copy Cloner backups of my main 1 TB SSD drive) has disappeared. Not too surprising, and I do have Time Machine and Backblaze backups of the main drive, so I'm not concerned.)

The main issue continues to be the inability to print from any app as described above. Hopefully, there is something in the report that will point me in a helpful direction.

Thanks!

It usually is, and it would clear up the question about a 2009 Mac Pro running Mojave. It's not supposed to run anything later than El Cap. A 2010 model, yes, but not 2009.
