I'm having trouble finding references to a Brother LC980 printer, though I can find plenty of references to LC980 ink cartridges. Would you check the nameplate on your printer, and confirm the model number? Most Brother printer model numbers start with HL, DCP, MFC, MP or M.
Doreen I waited for you that day to start the session but got no reply from your side.
I am providing you the link to driver software. Just select the operating system and download the file. Once download is finished, just open that file to install the software.
