By default the printer file that is used to spool a job log is QPJOBLOG. You can have multiple QPJOBLOG printer files on your system. In QSYS the output queue that the OUTQ attribute uses is QEZJOBLOG, in library QUSRSYS. When the system creates a job log, it looks for the printer file QPJOBLOG in the job's library list. The first one that is found is the one that it uses. You use the character-based interface to adjust these settings.
