With this useful plugin you can monitor easily your network printer.Download and move it to directory with the other plugins.In my case the directory is /usr/lib/nagios/plugins/.Make sure the snmp is configured on the printer side.Now, lets’ test the plugin root@icinga:/usr/lib/nagios/plugins# ./check_snmp_printer -H 192.168.0.75 -x "MODEL"
"Xerox Phaser 7400DN;PS4.2.0,Net25.72.10.07,Eng0.11.2,OS6.26", Serial # XXXXXXXXX

Now, we have to define host, check_command and services for our new object.
root@icinga:/usr/local/icinga/etc# vim objects/Default_collector/hosts.cfg
define host {
host_name Printer
address 192.168.0.75
max_check_attempts 1
check_interval 1
retry_interval 1
notification_interval 1
notification_options d,n
check_command check-host-alive
check_period 24x7
notification_period 24x7
contact_groups +admins
}
