8.4. Set the default queue

After the queues are saved, the default queue is adjusted. It is adjusted via IPP calls. The default queue is stored in /etc/cups/printers.conf if CUPS is used in full server mode (and in this case it is ensured that no queue is marked as default in /etc/cups/lpoptions), or in /etc/cups/lpoptions if running in the CUPS client-only mode and user wants other queue than the server default one as his default.
