########################################################################
# #
# This is the CUPS client configuration file. This file is used to #
# define client-specific parameters, such as the default server or #
# default encryption settings. #
# #
# Put this file on /etc/cups/client.conf (system use) or #
# ~/.cups/client.conf (personal use). #
# #
########################################################################
#
# ServerName: the hostname of your server. By default CUPS will use the
# domain socket /var/run/cups/cups.sock or the value of the CUPS_SERVER
# environment variable.
# ONLY ONE SERVER NAME MAY BE SPECIFIED AT A TIME. To use
# more than one server you must use a local scheduler with browsing
# and possibly polling.
# The IPP version (2.0 by default, can be 1.1 or 1.0) can be specified
# to access older servers.
#
#ServerName /domain/socket
#ServerName myhost.domain.com[:port][/version=1.1]
#ServerName ip-address[:port][/version=1.1]
#
# Encryption: whether or not to use encryption; this depends on having
# the OpenSSL library linked into the CUPS library.
#
# Possible values:
#
# Always - Always use encryption (SSL)
# Never - Never use encryption
# Required - Use TLS encryption upgrade
# IfRequested - Use encryption if the server requests it
#
# The default value is "IfRequested". This parameter can also be set
# using the CUPS_ENCRYPTION environment variable.
#
#Encryption Always
#Encryption Never
#Encryption Required
#Encryption IfRequested
