1 - I do not know perl!

The script / usr/lib/cups/backend/cups-x2go making the task of printing has
permissions 0700 and owned by root and group is root

Reading the script I can see references to a user x2goprint, that is not created
on my system.
Instead it is added to the file / etc / sudoers

What we still do not recognize is how backen detects user's (not x2goprint user
$spooldir) spool directory:

How can i debug. What are those statement to make the script log to syslog?

Thanks
