I have Brother MFC-J6520DW I bought in 2016. It's running on Mac OS El Capitan. I was printing a Photoshop text document when it kept on printing continuously. I tried to delete the printed files on queue but I it kept on printing blank pages. It generated 431 "printing jobs" on queue although I did not initially press print. Please see attached screenshot. I can't delete the "Ready to Print" prompt either. I can't find my Wireless connected print icon in my Utilities in my Application. Any suggestions? Thanks. Jos
