When the printer runs Ghostscript to convert the output into a PDF document it has a default timeout of 300 seconds (5 minutes). In case Ghostscript is still running after the timeout has expired it is terminated. This is done to prevent a crashed instance of Ghostscript to remain in memory if something goes wrong.
A timeout can cause problems if Ghostscript hasn't finished because it is working on a huge document. In this case you might experience incomplete PDF documents as a result of the Ghostscript process being terminated. You can change the timeout to fit your purpose. This is done using a setting named GhostscriptTimeout.
; Set Ghostscript timeout to 10 minutes
