ValidateCerts Yes

The first line is to tell which server to use, and the other lines
for security. This way of doing means that everything is configured
on the server.

This has been deprecated at my lab, and now, the printers need to be
configured directly on the client side. In case you want something
like that, AFAIK, there are 2 solutions:

Manual: something like
  lpadmin -p <name> -v <URI> [ -E ] -m everywhere -L <location>

Automatic with the cups-browsed package:

Description: OpenPrinting CUPS Filters - cups-browsed
 This package provides cups-browsed, a daemon which browses the Bonjour
 broadcasts of shared remote CUPS printers and makes the printers
 available locally, replacing the CUPS broadcasting/browsing which was
 dropped in CUPS 1.6.x. This way the old behavior of having the remote
 printers available automatically is now re-implemented with Bonjour.

(However, it appears that because of that, on my laptop, I now have
dozens of ghost printers, and this is annoying.)

I suppose that this is because you already have a server that is
already running and listening on these ports. Or you started the
server too soon after the old one terminated.

::1 is the IPv6 loopback. Perhaps listening on it is the default
(this makes sense), and perhaps even if it isn't setup (as this
is unusual).

THe issue has been fully dealt with. In short:

  No local printers leads to an empty localhost:631 and 'lpstat -t'.

THere isn't any issue whatsoever. You seem very reluctant to incorporate this
basic fact into your thinking. THe room is empty.

May we have 'lpstat -t' from a buster machine that is not bpi54?

[Informative info from a number of machines snupped.]

All the displayed queues are local and have either been set up manually (ipp://...)
or autmatically by cups-browsed (implicitclass://...). A manual setup on a
bullseye machine would involve the raw or everywhere model. A client.conf is an
is an alternative.

But it doesn't seem to work in armbian bullseye, who uses debian repo's 
for everything not involved with booting. Most armbian stuff is u-boot.

I now have different results between bpi54, which works, and bpi51, 
which does not. The two are I believe configured identically in /etc/cups.

Close, I wanted to be able to print from the bpi from any app on the bpi 
that had a print this option.  Now I can.

No, that kills the cups ability to query the network even with the 
Server named in client.conf. It even logs it as a failure, on the bpi5 
but doesn't say why.

Untried, so can't say.  And I've not read far enough to see that as an 
example.

Thanks Greg.

My best guess is the Server directive in client.conf was rejected 
because there was already a couple "Listen" directives pointing at 
itself.  Remove the main one and the client.conf was able to take over.
Or the substition of a "Listen ipv4-address-of-server:631" is also a 
possibility.

Whatever, the point now is that it Just Works.

A lot of hacking on C-89 has taken place since the last C book was 
published by K&R, so I am not the C guru I was in the 1990's.

I'm now 88 yo and some of me has gone to the dogs too.  Take that as an 
admission that my diagnosis might be wrong, but I've been chasing 
electrons to make then do useful work since about 1948 when I quit 
school and went to work fixing them new fangled things called tv's.

Take care & stay well, Vincent.

Please stop spreading misinformation. I have a Brother MFC-L2740DW 
(which I believe is the exact model you have, or if not very similar) 
and it works perfectly with the "driverless" approach, both with the 
cups ppd generator (everywhere) and the cups-filters pps generator 
(driverless). The first one leads to slow printing for some reason, and 
I had to select "high" quality to get standard quality; the second one 
is as fast as the proprietary driver. Auto discovery with cups-browsed 
also works. There might be some specialized options only available in 
the proprietary driver, but everything needed for general use (tray 
selection, duplex, etc) is available in the driverless driver.

The proprietary driver is fine and works well, if it suits you, feel 
free to use it. Just be aware that it's only available for i386, not 
amd64, so in a desktop pc you'll need to add the i386 architecture. On a 
Raspberry Pi or other arm computer you won't be able to run the 
proprietary driver.

But please don't say it's the only option because you've been unable to 
use the other ones.

You just showed that it doesn't Just Work, which is exactly why I run 
the brother drivers, which run just fine on a 6 core i5. Every feature 
this printer has, I can adjust from the cups menu's. The driverless 
setup can run this inkjet, w/o duplex because its w/o tray selection, 
printing everything on paper from the top smaller tray normally loaded 
with 50 cents a sheet glossy photo paper.

An arm computer has no need to run their driver, and yes, the rpi4b 
running 1500 lbs worth of 80 yo Sheldon lathe, but running buster sees 7 
shared printers from this machine right now. And they are all usable 
from that keyboard.

If their driver ever had an i386 limitation its news to me.

This printer also has a cat5 feed, with an address in my local 
192,168,xx, block, so even if its not plugged into a given machine, but 
the printer and the scanner should still be available at it ipv4 
address. That should be found by cups running anywhere on the property, 
it is not discovered. But I'm mistaken, I now recall unplugging the cat 
5 cable about 2 years ago. USB is faster at data transfer. By about 5x.
