Public bug reported: I have an HP LaserJet M551dn printer which usually works just fine with CUPS. Tonight, however, I discovered that I was completely unable to print one particular PDF file (unfortunately I can't provide you with the file because it's a scan of a tax form with PII on it). CUPS claimed that it printed the file and there are no errors in the log. On the other side, the printer doesn't show any trace of the file haven't been sent to it. The print job isn't in the job log, and at no point while CUPS claims it's printing does the printer make any noise or any of its lights blink as they usually do when a job is being sent to it.
I don't know how to debug this further. I'm attaching the section of /var/log/cups/error_log from the attempt to print the file. This is reproducible every time with this particular file, including immediately after updating to all current Jammy packages and rebooting.
