It is configured by default to it has to be changed
See below working config. You will need to have iptables to allow access
from remote connections. /etc cups and hp dirs.
cupsd.conf:
MaxLogSize 2000000000
# Show general information in error_log.
LogLevel info
SystemGroup sys root
# Allow remote access
Port 631
Listen /var/run/cups/cups.sock
# Enable printer sharing and shared printers.
Browsing On
BrowseOrder allow,deny
# (Change '@LOCAL' to 'ALL' if using directed broadcasts from another
subnet.)
BrowseAllow @LOCAL
BrowseAddress @LOCAL
DefaultAuthType Basic
------
hplip.conf:
# hplip.conf
[hpiod]
# port=0 (dynamic IP port)
port=2208
[hpssd]
# port=0 (dynamic IP port)
port=2207
[hplip]
version=1.7.2
jdprobe=0
Iptables needs:
-A RH-Firewall-1-INPUT -p udp -m udp --dport 631 -j ACCEPT
-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 631 -j ACCEPT
