HP Smart (v4.5.2) can't forget the printer on MacOS 10.15.4 (Catalina)

[flutii]

I don't know why I had the several (7) repeated offline printers. I tried to remove them following the instructions (see the pic): I clicked "Forget This Printer" but nothing happened after I clicked the button and selected to "Forget Printer" in the pop-up window. These printers couldn't be removed at all. I am still able to add the same printer to HP Smart and I can print as well. I've tried to reboot the Mac, reboot the Printer, delete the HP Smart App and reinstall, delete the Printer from the Mac System Preferences (Printers&Scanners), etc. I am out of ideas so I think there are probably some nasty bugs there. Even I delete HP Smart and reinstall it, those phantom (offline) printers are still there. So now I have 7 of them and it's very annoying. If someone has encountered the same problem, would love to hear your ideas...  

If HP tech support team is on this forum, the SW versions are in my subject, and my printer is updated to the latest FW.

Thanks!

@flutii, Welcome to HP Support Community!

Did you just move the HP Smart app to trash or did you also clear the contents from the trash?

Removing it completely from the library and trash will help us clear the cache from the system.

Follow the steps below:

1.) Open Finder and click Applications

2.) Move HP Smart App to Trash and clear the Trash.

3.) Open Finder then click Go and Click Home.

4.) Click View then Click Show View Options. Check the box Show Library Folder.

The change is instantaneous and the Library folder will immediately become visible.

5.) Open Library and Open Application Support, move the HP Smart folder to Trash and clear the Trash.

Download and install the HP Smart app.

Hope this helps! Keep me posted.

Hi, actually I tried that but I didn't see the HP Smart Folder in the directory you provided. Instead, I found it in this directory: /Users/usernameXYZ/Library/Containers/com.hp.SmartMac/Data/Library/Application Support/ . After I deleted the folder and re-installed the HP Smart App, it seemed a clean installation. Steps below:

1. I deleted my "HP Smart App".

2. Then I deleted the app in the trash can.

3. Then I deleted "HP Smart" folder in the above directory.

4. Re-installed the HP Smart App. 

5. Followed the instructions to connect to the printer and such and problem solved! 

Thanks!
