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.
