my imageclass 8380Cdw will print a beautiful black and white printer status and config report (initiated from printer). But it will not print any black and white when attempting to print a file from macbook air computer. Comes out black with smudge...
actually I located the updated driver for my mac version on the cannon website, downloaded, set up the printer again on the mac, and this resolved the problem. Please consider providing this advice to future folks with my concern.
