Welcome to LQ.
It would probably be best to start a thread with a detailed title about the printer in a relevant forum, perhaps the Mint forum. This forum is just for introductions and persons who can help you might not see your post here.
should help you frame the post and include the relevant information.
You might also check the logs in /var/log/cups, particularly the access_log and the error_log. Information in them might help persons answer your question.
I checked the Open Printing database
and that particular printer was not listed, but perhaps some of the listings for similar Brothers might help.
