Hi, When I go to system preferences > Printers & Fax I see 3 printers listed. When I have a document open and go to Print, the dropbox with the list of printers is full of duplicates and old printers. How do I reset the list so I can start fresh? In System Prefs>Printers I can right click and reset that list but the list in the dropbox when you try to print is still full and chaotic. Does anybody know how to reset that list?
