This document (7021359) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 12
cups > 1.6b1

Situation

Jobs sent to printers which are unresponsive for a longer period are dropped by cups. When activating debug mode the following message can be found in /var/log/cups/error_log :

E [08/Sep/2017:01:18:05 +0200] [Job 4] The printer is not responding.
[...]
I [08/Sep/2017:01:19:02 +0200] [Job 4] Canceling stuck job after 10800 seconds.

Resolution

Set MaxJobTime in /etc/cups/cupsd.conf to 0 to disable this behavior. See man 5 cupsd.conf for more information.

Cause

cups 1.6b1 introduced a changed behavior that cancels jobs after 10800 seconds of printer unattainability by default.
