cupsd.conf - server configuration file for cups
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. Com-
ment lines start with the # character. The configuration directives are intentionally sim-
ilar to those used by the popular Apache web server software and are described below.
The following directives are understood by cupsd. Consult the CUPS Software Administrators
