I used PowerShell and it couldn't find the original printer. I guess it's gone now. I have my reinstalled default printer and it works so I guess this issue is resolved.
I reinstalled the printer again and this time it showed up, but I can't rename it because Windows says there's another printer with that name. The original printer is in the system but does not show on the list so I can't manage it or uninstall it.
I have a Canon TR8520 Printer/Scanner. It works perfectly fine and all my apps see it as the default printer, but Windows does not list it. It is absent from the list of printers in Settings>Bluetooth & Devices>Printers & scanners. Is there a fixed for this?
