You'd think that was good news, but we've been unable to find any way to
make the queue for this "driverless" instance of the printer function
properly.


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).

Definitely a firmware bug; the printer is non-conforming. cups-browsed
puts the incorrect information in the PPD because it queries the printer
and that is what it is told.

Seems like this must be the case. Too bad. Updating firmware on this thing requires trundling it out of the den, down the hall and to the living room so I can attach it to a Windows box.

I'll look into this and get back to you and Curt to let you know whether or not the printer is already running the latest firmware.

BTW at the Brother site I think they're recommending updating the
firmware for this printer (maybe not for the reasons explicited here).

HTH.

If the OP has his testing systems up-to-date, he should not be seeing
this bug.


All three testing systems are upgraded daily, so I'll check into it and get back to you.

Again, many thanks to you and Curt.
