How to delete old printer from inside Firefox ?

more options

I got an new printer a couple of months ago. I have deleted the old printer from the devices in my computer and deleted the program. When I go inside Firefox about:config this old printer is still there. How can I get rid of the old printer entries in the about;config. There is no delete in the menu. Thank you.

In about:config right-click each of the preferences for that printer and use Reset. Then close Firefox - restart Firefox and those prefs should be gone.
