How to remove a printer from the registry

Thank you Spark,

OK, I found it but unfortunately that didn't solve my problem

Have a great weekend and thanks again

Hello

In the registry editor, click on "Edit" then "Find" and enter the name of your printer; it will open all the keys containing its name. For me, it is listed under HKEY_CURRENT_USER\Printers.
Do the same with the scanner.
Be careful with registry modifications; remember to make a backup before changing anything.
