NAME
       cupsd.conf - server configuration file for cups

DESCRIPTION
       The cupsd.conf file configures the CUPS scheduler, cupsd(8).  It is
       normally located in the /etc/cups directory.

       Each line in the file can be a configuration directive, a blank line,
       or a comment. Comment lines start with the # character. The
       configuration directives are intentionally similar to those used by the
       popular Apache web server software and are described below.
