Canon printer stopped working, seeing error in /var/log/cups/error_log

iq2luc · 2025-05-05 13:44:37

Rolled back to Arch packages from 2025-04-29 and printing works again without any issues, with all printer / configuration options (https://hastebin.com/share/agujoyemip.console).

Here are the changed packages: https://hastebin.com/share/metayorere.console (from 2025-04-29 to 2025-05-05)

[~]> cat /etc/pacman.d/mirrorlist

Yeah, the big two ones are gcc(-libs) and libxml2 - gcc-libs being the more likely problem.
Do NOT try to stall either of those in isolation!

You'll have to either wait and hope for an updated canon driver rebuild (afaiu those are only available as binaries?) or try to get IPP everywhere working (where every indication is that this should work and will rid you of any dependency on proprietary canon drivers and such incompatiblitly issues)

Seeing the same thing. Tried sending to the printer using LPD, IPP, and the original socket: that worked for years. Always stuck with the "libcanon_pdlwrapper.c" error. The printer was accessible prior the large daily update on 5-2 (or 5-1... it's all a blur) and the CNRDRVCUPS update from the AUR.
Also tried it on a Fedora machine -- exactly the same results.
Stuck with printing through our wired network using an Android phone after exhausting all options.
Looks like Cups was updated on Apr 11th according to the ALA. Did you update Arch after that date and print successfully?

Yup. In fact, I had printed on 5-2 (or 5-1) literally an hour before the Arch update which resulted in what we're experiencing in this thread.

iq2luc · 2025-05-05 14:12:44

Got it! :-)
The culprit is libxml2 (2.14.2-2).

Just downgrading it to libxml2 (2.13.8-1) (and its two dependencies libarchive (3.7.9-2 -> 3.7.9-1) and sane (1.3.1-3 -> 1.3.1-2) solves the problem.

Do you get away w/ https://archlinux.org/packages/extra/x8 … l2-legacy/ ?

Interestingly, I had a couple workstations using IPP everywhere with the MF232W which does light up the printer status window, but the printer log shows "connecting to printer" indefinitely or displays a completed job (printer shows no sign of activity) and Job Competed in the logs.

Funny, I posted this on Reddit https://www.reddit.com/r/ManjaroLinux/c … are_button about 4 years ago explaining how to use IPP.

Sidenote, using Arch for 10+ years and there's always been a way around issues -- we'll get there

Yes, using the "legacy" package works around having to downgrade the libxml2 package (and its two dependencies).

Back in (printing) business again without having to downgrade anything (Arch is up to date + libxml2-legacy installed).

Thank you.

Are you seeing any issues when downgrading libxml2?

If the printer doesn't support IPP everywhere/airprint (preferable solution for sure) please see https://wiki.archlinux.org/title/CUPS/T … #Debug_log and post the log after attempting to print some file.
On a wild guess, it's libxml2 but do NOT downgrade that!!
Post the cups debug log, we'll see on from there.

No issues, but I only used that workaround for about 10 minutes, because I switched to libxml2-legacy package and everything works fine now without having to downgrade anything.

iq2luc notably also downgraded its apparently two only consumers on that box, but that's not gonna be your average desktop system: https://archlinux.org/packages/core/x86_64/libxml2/

...but still, in my opinion your suggestion for installing libxml2-legacy should be the "official" workaround / solution for the time being.

Thanks again.

Yes, because otherwise you'd break all that stuff you listed

I'll re-iterate though that, also because cups has plans (don't ask me what thesy look like) to abandon printer drivers in favor of IPP Everywhere, you might still want to look into that vector (now in addition - just make sure that the log doesn't mention ufr2 when trying to print this way and have a look at the printers web interface for possible configuration settings/hints)

Going w/ themew's manjaro post, ipp://<IP_OR_DOMAIN>:631/ipp shall work on canon (it would have been nice if the url had been standardized and not be the root or /ipp or /print or /queue or whatever else vendors could come up with)

Going with your suggestions I already tried that (IPP Everywhere route), but no luck on my side (just filled https://github.com/OpenPrinting/cups-filters/issues/635).

AFAIK that's part of a general migration to "driverless printing". Microsoft has similar plans. Looks like the industry is tired of (writing) crappy printer drivers .

I have changed the dep from libxml2 to libxml2-legacy, please test this PKGBUILD.

Suffering from an almost identical problem. I've been using a FollowMe printer at work for years with no issue, but it stopped working some time in the last week.

src=libcanon_pdlwrapper.c line = 514, err = 0¥nError Response:ReqNo=2,SeqNo=3,opvpErrorNo=-2

Installing libxml2-legacy has not helped.

I'd really appreciate any advice on how to investigate this or any solutions you might have.

All good on my side, thank you.

In my case, I rolled back to last system state that I knew it was working (as suggested by seth) and I compared what packages changed that may be related to the printing.
After that, I updated the "interesting" packages one by one, or group by group (it helps a bit of knowledge / "engineering flair" about which packages may be involved) and so I found that libxml2 was the culprit.

Also check the CUPS error_log, maybe it gives you some / more hints (maybe even put the CUPS log in debug mode by setting LogLevel debug in /etc/cups/cupsd.conf and restarting cups.service).

And last but not least, this was my first experience with printing issues, so please also consider ideas from more experienced / knowledgeable people.

seth · 2025-05-06 15:17:16

@smolloy while I don't think that should be necessary, did you restart cups & the printer afterwards?
Which driver package do you use?

pacman -Ql cnrdrvcups-lb # assuming that's the package

themew · 2025-05-06 15:51:03

Just installed 1:6.10.1.01-2 from the AUR. Flawless.

Thank you all and Lone_Wolf -- The sweet sound of printing again... I cannot thank you enough for fixing this.

seth · 2025-05-06 16:06:36

I still don't get how IPPE/AirPrint doesn't work on those things - feel free to open a thread about that if you care…

I rebooted my laptop. The printer is a "FollowMe" printer at work, and I don't have permission to restart it.

I have been using cndrvcups-lb and cndrvcups-common-lb (note _not_ cnrdrvcups-lb -- notice the small difference). I tried reinstalling it, but now it won't compile.

printerinfo.c:204:20: error: implicit declaration of function ‘cupsGetPPD’; did you mean ‘cupsGetFd’?

Something seems very broken...

smolloy · 2025-05-07 07:40:14

But taking the hint from your message and installing cnrdrvcups-lb seems to have fixed the problem.
Thank you!

@Lone_Wolf, maybe time to file a deletion request

Lone_Wolf · 2025-05-07 10:26:43

Good idea, I filed deletion requests for cndrvcups-lb and cndrvcups-common-lb.
Also removed the reference to them from the wiki.
