I ran into an issue where my HP laser (wifi M252) would not print for a desktop installation of tumbleweed but would for a virtually identical system on my T480 laptop. Both systems had the printer last set up by Yast but the Yast printer module had been silently dropped an I was unaware that CUPS was now the only printer utility.
A marathon session with Anthropic's Claude pointed to a self-signed certificate that had expired in 2025 and for some reason had not been renewed (I know nothing about printer certificates and care even less!). In and of itself this still allowed the T480 to print and THIS led to service becoming nixed (I suspect by some 'security' _feature_).-a I have the entire session as pdf but suse-paste wouldn't let me put it up, the short of the long being that I had the printer admin page issue itself a new self-signed certificate, cleared all buffers and settings and that fixed the problem.

That might have something to do with https to Port 631 of CUPS. It
is protecting packets exchanged with the CUPS control. I don't think
the printer is involved there, but I could be wrong.

I've not heard of any certificate ceremonies for printers themselves,
so I don't know how any detail like that would work. The printer in
the diagram, could be Wifi or Ethernet for example, and while not
practical, the printer could be some distance from the "cupsd" controlling it.
You could ask your LLM-AI, what paths are encrypted, and what facilities--
are needed for the encryption and remote communications, to work.
Some printers, are Wifi only, and that's so the printer ink scam can work.
If your printer has a USB cable as well, there are fewer options for shenanigans.
And the USB cable protocol does not particularly need "protection".
Whereas other path-types to the printer (Wifi/Ethernet), could be worthy
of protection (if the printer is miles away from the CUPSD driving it).

The local store that actually has any printers in stock is like 600 km
away for me. I bought my first Hp-M252 many years ago, and it went tango-uniform after I fed it some noname but 1/3-price 3rd-world toner.
The second one I bought has been working more flawlessly than ANY other printer in my 40 or so years of computing! The 'designated' toners do
cost an arm and a leg though. With I don't even know how many phones and
at least 4 computers regularly soliciting it I've had it on wifi all the time, so far with zero issues except this last one.

I have an HP Laserjet M209dw, B&W printer, on another location. It is actually one of those that want to be registered to a toner replacement program and is on WiFi. But it does not know my name or address, I never registered, so it keeps quiet.
Actually, after a few years, it is still on the first courtesy
cartridge. I use it little and it was cheap, refurbished.
My printer here is on its last cartridges. It is a color model, CP1515n, purchased 2008-09. Via ethernet. Thing is, rubber rollers have hardened
and can't handle 110 grams paper. So I will replace it soon with another one, when the toner is spent.

Just did another rabbit-hole run with Claude, at the end of which I had a hunch:
If I connect with usb wifi transceiver wlp17s0u7u1 then the problem does not exist.
If I connect with the Asus x870e-ProArt board's native wifi wlp11s0 then on attemting a print I get:
"Connecting to Printer"-a ....followed by
"The printer is unreachable at this time"
If I disconnect the onboard wlp11s0 and connect with wlp17s0u7u1 then the problem is gone again.
If I then reconnect-a with the usb wlp17s0u7u1 transceiver then the onboard one dies not di9sconect as it shopuld but stays connected and behavior is as if it was the only one connected (above).

We had a few lasers at work, which were printing 2000 sheets a day.
How many computer store printers today, could do that ? One of those
used liquid toner (black particles in kerosene, marked flammable). The
other one used toner carts. And the toner in that case was the
dry, non-polymer type.

Are these connections via Wifi Direct, rather than through the router ?

If you have a router, all the devices should be using the router.

https://bdsdoc.com/blog/difference-between-a-liquid-and-a-dry-toner-printer/
"A liquid toner printer uses tiny particles of colored powder, called toner,
suspended in a liquid carrier - usually a type of oil. This technology is
typically found in digital presses and commercial printing systems, rather
than in standard office printers.
In this process, the liquid toner, composed of extremely small pigmented
resin particles, is transferred to the paper, where it is fused as the
carrier liquid evaporates.
Benefits of Liquid Toner Printing
Due to these qualities, liquid toner printing is favored in professional and
commercial settings where print quality is critical. Its strengths include:
Exceptional color vibrancy and image detail
Smooth gradients and photographic-quality output
Minimal fading or smudging
No warm-up time required
High-speed production for commercial print jobs
"
So that's the basic idea.
That's not exactly the description for our little printer,
but it's close enough.
We couldn't really play with that machine, because the drum
was supposed to be kept out of room light. The replacement drums
cost $3000 each, and the person changing that out had to be
following the instructions. I don't think the poor thing is
as bad as photographic film -- the warning is not to leave
room fluorescent lighting on it for eight hours while
you have a "long lunch". Some of the toner cartridges with
belts (the "purple belt"), those too had room light warnings
to not leave them out for too long. I don't recollect anyone
giving a damn about those, as those might be $100 or so.
Those could be slapped in a lot faster, so they were
unlikely to be damaged during install.

If you suspect LLM-AI quality issues, you can:
1) Change the control at the bottom of the screen to "High Reasoning".
This makes almost no difference to the quality of the answer, but
it does tend to make the machine more "self-aware". It will admit
when it seems to be guessing at stuff. There seems to be some sort
of convergence property it can measure or check. We have no control
over what the "settings" in the bottom menu say, so there might not even
be such a choice offered there.
2) If no control is present, try a statement like this.
"How many holes does it take to fill the Albert Hall?
Work slowly and carefully, giving a precise answer."
as that is supposed to flip the same switch on it. The strategy planner
examines the second sentence, and concludes High Reasoning is required.
And yes, there is a delicate balance between providing not enough material
in a question, and providing too much material.
If you know the answer to the question, that makes it easier to feed
keywords into the question. Keywords make nice anchors. If you know nothing about the question you're asking, then salting it with keywords is
going to be harder to do.
It never gets into a flap about spelling errors. It never even mentions
them! Which I find, pretty amazing. Just like when it does OCR, it uses
the context of the material, to suggest the right spelling choice. It
also seems to have an uncanny ability to extract things you haven't explicitly said. For example, when I asked it to write a computer program,
it merely assumed I wanted the "best algorithm". It then tells me
what the best algorithm is... then... it writes a computer program using
a different/weaker algorithm. I love stuff like that, high comedy for sure. But there's no point slapping the machine around, as slapping them
around, they don't remember that for very long. They don't mind
giving you the wrong answer twice. If they write an apology,
they don't really mean it.
*******
I don't resort to chat sessions too often.
I write a detailed question. If it's a flop, I close the
window. And it might then purge that material when you
open the window later and "ask a brand new question".
I find I need to write up the question in a text editor
first, then I copy/paste into the query box, and use the
up-arrow icon to submit it. This is intended to make me
spend more time, crafting the question. Sorta like
slapping it around, in advance :-)

The OP's Laserjet M252 is subject to a somewhat similar scam if he
hasn't turned off the automatic firmware updates. The Color Laserjet
M254dw that I bought on ebay must have been connected via usb, because
the auto-update was on but it still had the original 2017 firmware.
First thing I did was to disable that auto-update "feature" before connecting to my network. I connected via Ethernet cable, because it's faster than wifi.
Those periodic firmware updates can prevent aftermarket toner carts from working at all. I think it was in 2022 (pulling that date from memory,
could be wrong) when HP issued firmware updates to a lot of their
printers that disabled aftermarket toner carts. There are sites and
Youtube videos about how to "downgrade" the firmware to before this happened.
Some toner vendors claim their custom cartridge chips will work with any firmware, but fortunately I haven't needed to test that theory yet. The printer warns me these are not Genuine HP, but works with them anyway.

HTH whomever runs into similar.
Just did another rabbit-hole run with Claude, at the end of which I
had a hunch:
If I connect with usb wifi transceiver wlp17s0u7u1 then the problem
does not exist.
If I connect with the Asus x870e-ProArt board's native wifi wlp11s0
then on attemting a print I get:
"Connecting to Printer"-a ....followed by
"The printer is unreachable at this time"
If I disconnect the onboard wlp11s0 and connect with wlp17s0u7u1 then
the problem is gone again.
If I then reconnect-a with the usb wlp17s0u7u1 transceiver then the
onboard one dies not di9sconect as it shopuld but stays connected and
behavior is as if it was the only one connected (above).
In the above I had the id's ack bassward, wlp17s0u7u1 is the on-board
wifi. My printer was still short on CYAN toner because I wanted to get
to the bottom of this bullshit before giving it the new cartridge
waiting on my desk.
I updated the tumbleweed system but even though the printer panel is set
up to print B&W if a color toner falls short it simply does not print AT ALL. The only thing the printer dialog/annunciator says is that it is
trying to connect to the printer, but it never does.
I disconnected the onborad wifi antenna but that wifi remained still not only available it couldn't even be removed from the NetworkManager list
of available transceivers. The ONLY way I can print is by disabling the onboard wifi in BIOS and rebooting. THEN cups gives me printing as it
should so as far as I can finger it out the problem is with the onboard
wifi driver AND whatever ELSE it is that makes real control over it 'problematic' (i.e. I have always preferred USB wifi transceivers for exactly this reason: their physical removal cannot be overrriden by software).
Although I do not have an answer or a solution at least I think I know enough about the issue to do alternative printing if I have to, with
that I out of the way I swapped out the empty cartridge but the onboard device will remain disabled in BIOS.

Seems you are using Wi-Fi Direct.
No, it's set to OFF. When it's ON then the NetworkManager display shows
it explicitly.

Could it be trying to use some sort of driverless protocol, like
Airprint or IPP Everywhere? CUPS has been moving toward driverless
printing for years.
