When I print certain webpages with firefox, or when I use atril to print
a PDF produced by "Save as PDF" in firefox, it does not work.ÿ The
printer produces a single "click" sound, then nothing.

Iÿ don't know whether it is all PDF's/webpages or only some. An example
is the simple html page

ÿ ÿ https://www.dybdal.dk/kbp-jd/

I have presented the problem for ChatGPT, and here is some of its output:

Let me restate the really important facts to make sure we?re aligned:

Debian Trixie 13.3
Native firefox-esr, not snap/flatpak
lp < text ? works
Atril prints some PDFs ?
Atril fails on Firefox ?Save to PDF? PDFs ?
Firefox Print ? Save to PDF works
Firefox Print ? printer ?
Printer clicks once ? job dies
No CUPS errors logged
Worked before ? broke after system updates
That combination points very strongly to a PDF compatibility
regression, not a driver or CUPS core issue.

and

Fastest confirmation test (very telling)

Take a Firefox-generated PDF and down-convert it:
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 \
ÿ ÿ -dPDFSETTINGS=/printer \
ÿ ÿ -o fixed.pdf original.pdf

Now try printing fixed.pdf with Atril.
If it prints

100% confirmed PDF filter incompatibility

and it does print.

My knowledge of how printing in Linux works is very limited. There
should be absolutely nothing non-standard in my printer setup (an HP
laser printer, standard installation in Trixie).

ChatGPT suggests some workarounds, of which the one I liked doesn't
work, and the others require more than pressing ctl-p to print.

Is this a known problem?

Thanks,

Jesper

Does printing the test page from the printer settings work?
Is the job finished or failed and still in queue?
Which printer is it?

Does it have a copy function?
If so, does that work?

Yes.ÿ ChatGPT's idea, which sounded plausible to me, was that the PDF generated by firefox uses new PDF features that are not supported
further down the print data route.ÿ So it depends on the contents of the
PDF.

Is the job finished or failed and still in queue?

It is finished.

Which printer is it?

HP Color Laserjet Pro M255dw

Does it have a copy function?
If so, does that work?

Actually, I don't know, since I don't need a copy function.ÿ I can find
out, but not right now.

And thanks for your help.

Do you have CUPS installed? It has a web page to monitor print jobs at < http://localhost:631/>, including the option to print a test page and mo
nitor status of print jobs.
