Sure, CUPS does make it comparatively easy for "Joe Average" ... I've
found things to be about on-par when you're talking about small offices
though; where the print-jobs are pretty boring/standard (all text, all
b&w, all 2-sided, etc.). 

LPR/LPD needs a little extra setup at first, but then "just runs".

CUPS doesn't take as long to setup, but does require an hour or two
every few months to keep behaving ... but then again, those two sites
are also the busiest in terms of printing; so maybe that plays into it.

How do we define "modern"?  Just looked at a few Brother MFPs, and they
still support it (although I don't know how old the actual models are).

Sorting by "newest" on their (laser / color led) models listing results
in the "HL-L3270CDW" being listed as "newest" -- digging around, it
seems that it's a 2018 model.  Still has LPR/LPD listed under the
"Protocols" sections (both IPv4 and v6, actually).

I would expect that pretty much everything of theirs (well, at least in
terms of "business lineup") would then still support it. Their site
seems a bit broken right now (or perhaps it's on my end), so I can't get
at the 'home' stuff to check.
