cupsd.conf(5)
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. Note: File, directory, and user configuration directives that used to be allowed in the cupsd.conf file are now stored in the cups-files.conf(5) instead in order to prevent certain types of privilege escalation attacks.
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.
The following directives are understood by
cupsd(8).
