Available Printer List shows REMOVED printers
Thunderbird shows a long list of available printers when I go to print an email. Half have Been properly removed in Windows 10. They do not show on other apps nor in the Control Panel. The old printers' software has been removed. One even shows an old printer name followed by (copy). How do I remove the nonexistent printers from Thunderbird?

There are usually a lot of dead printer information stored in the prefs of Thunderbird. Use the config editor to remove prefs containing the key printer.
