You'd think that was good news, but we've been unable to find any

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.
BTW at the Brother site I think they're recommending updating the
firmware for this printer (maybe not for the reasons explicited
If the OP has his testing systems up-to-date, he should not be
seeing this bug.
My Debian testing systems are definitely up-to-date, but it appears that I
am still seeing the bug. Eyes are too tired for me to be able to go through
the suggested PPD edit and other testing. When the world is this bleary I
just can't count on getting dependable results.
Understandable. Sometimes it is better to leave it to another day and
look it with fresh eyes. TBH, that is also the way I feel now when it
comes to your switching off AirPrint not doing what is expected.
The workable solution for me right now is to use the MFC-9320CW driver. It
actually works quite well and gives me access to control of all printer
functions that I need.
Turning off AirPrint didn't remove the advertised driverless print option in
CUPS / system-config-printer / print dialogs. Oddly enough, turning off WiFi
Direct did eliminate it. I know I'm being simple-minded, but the printer's
wireless adapter isn't being used. It's connected to the router via
Ethernet. Why do wireless settings affect what I see of this printer on the
Nothing immediately springs to mind. Something to think about, even
though your desire not to see the printer has been sorted. No wireless
capability anywhere on the network?
Printer is connected to the network only via CAT6 to the router. All
computers are connected via wireless. But none of them has ever been
given permission to connect directly to the printer.
At least now we don't have to select between one queue that does work and
one that doesn't. Your suggestion about AirPrint / Bonjour in the other
message prompted me to look through all of the wireless settings. I'm
delighted not to have to look at the queue that doesn't work.
I'll eventually update the firmware when my attitude improves. The physical
process in our particular location is a little tough for me. Right now I'm
wondering why the version 1.08 firmware on my printer is not listed in the
Brother support site's update history. Their list jumps from 1.07 (which
came with the printer) to 1.09. They give no useful information about the
purpose of the update (or any of the previous ones). Looks like someone
there is just going through the motions.
I wouldn't want to point the finger at Brother. Other printer vendors
are not all that great with changelog recording,
Oh, I know. A support group is given lots of "motions" to go through,
and probably precious little time for the going. But that certainly
results in frustrations for end users who need information. When you're
using an OS other than Windows or MacOS you're going to feel short-changed.
I remember how annoyed I was once just after WinXP was released that my
wife connected a new HP printer to her system and just stuck the
included software CD in the optical drive. The software that got
installed was bigger than the OS. No foolin'. Memory may be failing me,
but I swear that at least a half-dozen services were installed without
so much as a by-your-leave.
Maybe I'd actually rather be short-changed, come to think of it.
