If you are running unmodified Oracle Solaris 11 Express, CUPS is already the default print service. If you upgrade to Oracle Solaris 11, you do not need to reconfigure any existing print queues by using CUPS. However, if you switched to the LP print service and configured printers by using the lp print commands, you must reconfigure these existing printers by using CUPS after the upgrade.
Caution - If you are running the LP print service, be sure to back up your /etc/printers.conf file before upgrading, as the upgrade process removes this file.
To determine which print service is enabled on your system, type the following command:
$ /usr/sbin/print-service -q
Reconfigure your existing printers by using any one of the methods that is described in this chapter.
