Nixpkgs version

• Unstable (25.05)

Describe the bug

I have a Canon MF753Cdw printer. I set it up on my laptop a couple of months ago. It uses CNRCUPSMF750CZS.ppd from the canon-cups-ufr2 package.

I updated my nixpkgs version and the printer became unusable. After investigating the CUPS logs, I see this:

Apr 06 16:16:04 hermes cupsd[2442]: [Job 66] /nix/store/84igp5b3zwgvdxig4yb7jzbc8jm8rxj3-canon-cups-ufr2-6.00/bin/cnrsdrvufr2: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

This happened pretty recently, so I implicate #381315 as it's the only PR that touched the package in a while.

Steps to reproduce

1. Set up a printer using a PPD from canon-cups-ufr2.
2. Set the CUPS log-level to debug.
3. Run journalctl -u cups -e -b -f | egrep -v '(\[Client|subscriptions|BusyState|Saving|Notifications|Notifier|MarkDirty)'.
4. Attempt to send a job to the printer and watch the log.

Expected behaviour

The printer prints.
