If you do that, you might as well configure the printer for a
pre-allocated IP address or a static IP address. I prefer
pre-allocated.

That would be a HL-L2395DW. I haven't had any experience with that
model.

I don't think Canon knows what Linux is. Nothing on Canon's web pile.
This page describes the typical ordeal process:
<https://www.linuxfordevices.com/tutorials/linux/install-canon-printer-drivers-on-linux>
I had one customer with a Canon imageCLASS something color laser
office printer. They had to hide any evidence that Linux was being
used in the office when the authorized service center tech was on-site
or they would (unofficially) refuse to work on the printer.
 
My guess(tm) is that your Linux problems are buried in Brother's
implementation of IPP. CUPS uses IPP to deliver printing that does
NOT require installing a printer specific driver:
<https://wiki.debian.org/CUPSDriverlessPrinting>
If one model printer works, but another model printer does not, it's
mostly likely a problem with the printers implementation of IPP. Not
much you can do about that except to check for printer firmware
updates. Since the lower end Brother laser printers cost only a
little more than a service call, I often suggested that buying a newer
model would solve the printing problem. I've only done that maybe 5
times, but it worked every time. Incidentally, Apple AirPrint also
uses IPP and can have similar problems.

The HL2170 (I think; cheapest one they made) came with CUPS and linux
drivers on the disk. So did the previous cheap Samsung, which was
always a dog and insisted on wrinkling paper. The disk with the 2395
had NOTHING except windows and mac stuff, but included the repair tools
you mentioned previously. I think there was some sort of automatic
setup when I turned on the 2395, but I just don't remember where its
info came from. Maybe when CUPS updated when I upgraded to Slackware
14.2. Just a guess.

I've got a chaap Canoscan scanner that does slides. Nice device, but I
had to use windows with it. SANE has some capability now, maybe even
full, but I haven't used it since 2005. Damn, I had to go look at the
dates on the files. I seem to remember making a phone call and being
told "We do not support linux" in a rather stuffy voice as if I'd asked
him about his porn preferences.

See above reference to porn...
 
I liked my Canon camera too (with serious exception regarding its
battery contacts), but I had to take the card out and read it
separately. Not a big problem, but still...

We have 3 slackware machines feeding the printer wirelessly via the
router. Two of them work, one obstinately refuses. The windows machine
is connected via USB and is no problem at all. I haven't tried printing
from my phone. We've temporarily given up getting the third machine to
print; workarounds exist.
 
I can't scan to my computer using the buttons on the printer; it just
doesn't see a PC and there seems to be no way to tell it there is one.
I could email it to myself or send it to dropbox et al., of course. Or
turn on the winmachine and then transfer the files to my REAL
computer... Fortunately Xsane works.
 
I have to wonder if a more user-friendly distribution would just take
care of the nastiness all by itself...
