Bug#879115: hplip can't print jobs with unicode surrogate characters
Package: hplip
Version: 3.16.11+repack0-3
Severity: normal
Tags: upstream
Dear Maintainer,
* What led up to the situation?
Tried to print PDF from evince
* What exactly did you do (or not do) that was effective (or
ineffective)?
Pressed the print button
* What was the outcome of this action?
The print job "stopped"
* What outcome did you expect instead?
Some printed paper.
Looking in the cups error_log I see:
D [19/Oct/2017:14:03:08 +0200] [Job 2204] File

Bug#1033616: cups prepends job number to job-name so job names near 255 characters may be too long
Package: cups
Version: 2.3.3op2-3+deb11u2
Severity: normal
Dear Maintainer,
* What led up to the situation?
I printed a page from firefox with a very, very long URL. Firefox used the
first 255 bytes of the URL as the job name.
* What was the outcome of this action?
The job mysteriously didn't print. Lookin in the cups log (with debug on) I
found the lines:
D [28/Mar/2023:18:14:44 +0200] [Job 365] job-name nameWithoutLanguage 365 -
https://xxx//xx
D [28/Mar/2023:18:27:36 +0200] [Job 369] Validate-Job:
client-error-request-value-too-long (client-error-request-value-too-long)
notice how the job name passed to cups ("https://xxx...";) is shorter than 255
characters, but when the job number "365 - " is prepended it is longer tnan 255
characters and so overflows.
* What outcome did you expect instead?
That my print job be printed rather than just geting stuck in the print queue
forever.
How to reproduce:
lp -o
'job-name=https://xxx//xx'
