avahi-discover is only for debugging, therefore it is not installed by
default. For actual printer setup and printing it is not needed. But
keep it installed, perhaps we need it again.
cups-ipp-utils is actually needed by the driverless utility, we will add
an appropriate dependency to the package containing driverless.

Your printer is actually an AirPrint printer and therefore the
"driverless" utility is listing it.

This is the information which the printer broadcasts into the network.
The "image/urf" in the "TXT pdl = ..." line is the MIME type of Apple
Raster, the print data format of Apple AirPrint. The other lines tell
about the capabilities of the printer, like whether it has duplex, is a
color printer, ... and the URL of the administration web interface.
The driverless utility and cups-browsed read this information to decide
whether the printer supports driverless printing.
This especially means that cups-browsed will automatically set up a
print queue if it is appropriately configured.
As you already told that you have set the needed configuration bits for
cups-browsed, I want to ask you to have the printer turned on, let it
complete start up, and now run the command
Does your printer appear in the list, with a URI which starts with ipp:
If so, please attach its PPD file (in /etc/cups/ppd/, file name is the
same as the queue name, with ".ppd" extension) to your reply.
Also try to print on the queue with different option settings.
Note that this print queue only exists as long as the printer is turned on.

This is because it found the correct PPD, which is auto-generated based
on a query for capabilities to the printer, automatically.

This system-config-printer always asks for, as it does not know how you
want to organize your print queues.

So you are successfully doing driverless printing with your Brother
printer and for the first time it works solely with free software,
without the awkwardnesses of Brother's proprietary driver.
Next steps to be sure whether everything works as intended:
Attach the PPD file (in /etc/cups/ppd/, file name is the same as the
queue name, with ".ppd" extension) to the answer of this e-mail. I asked
you for a PPD file earlier, but you have probably two print queues now,
one created by cups-browsed and one created by system-config-printer. I
want to know via the PPD files whether they are both created correctly.
Print some jobs with different settings (duplex, quality, input tray,
...) and from different applications. Does this work? If not, which
settings or applications cause problems?

See above, the driverless printing support generates an exactly matching
PPD file for your printer.
Note also that system-config-printer skips asking if there is an exactly
matching PPD but the web interface of CUPS always asks (but selects the
exactly matching PPD as default).
Do you have Brother's proprietary drivers installed? If yes, can you
uninstall them and check whether your printer still works with the newly
If your printer has a scanner and you have uninstalled Brother's drivers
and this leads to the scanner not working any more, please install ONLY
the scanner driver from Brother now, the printer drivers are not needed
