Hello, dwelch91!

Thanks for your response.

The print server has an IP and ping works, but what doesn't work is the snmp-related command (`snmpwalk -Os -c public -v 1 192.168.1.104 1.3.6.1.4.1.11.2.3.9.1.1.7.0`), which returns: "Timeout: No Response from 192.168.1.104".

I've installed several snmp-related packages and restarted the system, but I've had no luck. Here's the output of `aptitude search snmp`:

I have no idea on what to do next.

Also, ports 161, 162 and 9001 are still closed and there's no firewall installed. How can I make hplip listen on those ports?

Thank you.

HPLIP uses SNMP to communicate with the printer, so if the snmpwalk doesn't
work, then HPLIP will not either. Generally, if snmpwalk doesn't work, its a
firewall on your PC or a router issue (filtering or blocking those ports).
