Need help finding file Lex Bcd!

Can anyone out there tell me here I can find the file Lex Bcd? I was having trouble with my Lexmark printer and like a fool I went threw aand deleted everything that looked like it belonged to the printer( without backing up system ). Can any one tell me how to get this information back because now I can not install my printer at all. I am running Windows 2000 Pro. Any help I can get would be greatly apperciated.
