Configuration file modification
You can edit the /etc/qconfig file.
Both the enq command and the qdaemon command read the /etc/qconfig file when they start. The qdaemon command starts when you start the system; the enq command starts each time someone requests a print job. Therefore, if you change the /etc/qconfig file, the enq command reads the new version of the configuration file the next time it runs.
Do not edit the /etc/qconfig file while there are active jobs in any queue. Editing includes both manual editing and use of the mkque, rmque, chque, mkquedev, rmquedev, or chquedev commands. Use these commands when changing the /etc/qconfig file unless you want to do manual editing. For manual editing, first issue enq -G command to bring the queuing system and the qdaemon command down after all jobs are present. Then edit the /etc/qconfig file and restart the qdaemon command with the new configuration.
