Just very quickly found this bug that seems to be relevant to your case,
Jape. As you didn't describe the "garbled" condition of your printouts
with the "driverless" driver I can't be sure but it seems a fair guess.
Apparently a resolution dpi error (reported as 600x2dpi--firmware
bug?--and set that way by cups in the PPD. Workaroundable by modifying
the PPD manually as explained in the thread).
BTW at the Brother site I think they're recommending updating the
firmware for this printer (maybe not for the reasons explicited here).
