Can't scan from HP Photosmart

Sad that nobody was able to help with this issue here, but I did finally manage to solve it. Thought I had better post, in case someone finds themselves in a similar situation...

This was oddly the fifth attempt of doing the same or similar thing, so may be worth a couple of attempts. However, I used the HP Uninstaller (which you can download from the HP website) to uninstall any HP software and clear the printer from my Mac. I then went into both my system and user Library folders and deleted any leftover HP files. Then I reset the printer system (open up System Preferences > Printers & Scanners, right click in the printer list and click 'Reset printer system') and restarted my Mac.

After this, I downloaded the latest Mac drivers from the HP website and installed them. I then went to System Preferences > Printers & Scanners, and went to add my Photosmart B110a, and it finally discovered the printer as 'Bonjour Multifunction' which allowed me to re-add both the printer and the scanner.

Had done this a number of times - but the last time worked! So finally happy! The only thing I will add, is that the 'Airprint' option when going to install the printer is now oddly missing (although I do remember it originally being there before) - so wasn't an option to install. Not that I needed it this time around.

I have got a little further in seeing that my MacBook Pro is not seeing the printer as a 'Bonjour Multifunction' when trying to add it, instead only showing as 'Bonjour' and adding as a printer without the scanner function. This is in contrast to my partner's Mac, which does see it as a Bonjour Multifunction and so can scan - all on the same network, with the same version of Catalina.

But I seem to be no closer in fixing the issue!
