# classes.conf

The CUPS scheduler (cupsd) uses the /etc/cups/classes.conf file to store the list of available classes. This file contains only locally defined classes, not remote classes that are created automatically via browsing. Each directive is listed on a line by itself followed by its value. Comments are introduced using the number sign ("#") character at the beginning of a line.

While the class configuration file consists of plain text and can be modified using your favorite text editor, you should normally use the lpadmin(8) command, web interface, or any of the available GUIs to manage your classes instead. If you do choose to edit this file manually, you will need to stop the scheduler first, make your changes, and then start the scheduler to make them active.
