Hello Paolo Medina,
This is a peculiar but known issue that can sometimes surface after an OS upgrade, where the modern print queue and the legacy Control Panel view become desynchronized. The fact that you can still print from applications is a great sign. It means the core printing functionality is intact, but the user interface managing the printers is corrupted.
This typically points to a damaged Windows printer spooler and its associated configuration database. The steps you've already taken have likely compounded the corruption. Let's reset the entire print subsystem to a clean state. Please open an elevated Command Prompt (Run as Administrator) and run the following commands in order:
net stop spooler
del /Q /F /S %systemroot%\System32\spool\printers\*
net start spooler
After running these commands, you will need to reinstall all your printers one final time, as this process wipes the spooler's memory clean. This should rebuild the database correctly and make all printers consistently visible in both the Control Panel and the Settings app.
If this resolves the ghosting issue for you, I'd be grateful if you could hit "Accept Answer" 😊.
Jason.
