Thank you for your prompt reply!

The solution was to manually update each of my printer drivers to the correct manufacturer driver.

I tried all of your recommended steps, except for allowing tech support into my computer (which was an absolute disaster the last time I allowed it, but that's another story).  I also tried uninstalling and reinstalling QB 2024 with no effect.

I kept coming back to the strange situation that my default printer had somehow changed to Microsoft OneNote, so I did some more digging in the printer settings.  It turns out that for some reason ALL my printer drivers had been replaced with the generic "Microsoft IPP Class Driver".  (I have 6 printers from 3 different manufacturers, and every one of them was effected by this problem. Also, each of my computers with Windows 10 or 11 had the same strange driver change happen on them!  Notably, my Windows 8.1 computer was unaffected.)  I neither know how this initially happened nor how the problem was perpetuated during my removal and reinstallation of my printers.

Time will tell if my drivers get arbitrarily changed again...
