cupsd.conf(5)

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. 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.
