Model#? They only made about 300 different models of those things.
It's probably not important here, but may be later.

In Gentoo, if I didn't have the snmp USE flag defined, the hplip
utilities couldn't see or print to any networked HP printers. This
shouldn't be a problem under Debian-derived things though. Also, make
sure there aren't any overly-restrictive firewall rules in place like
a default DROP without a corresponding ACCEPT for whatever port this
is using. That'd cause the problems you describe.

Make sure you can ping the printer from the Ubuntu box first. Then
see if you can "telnet $PRINTER_IP 631" and get a connection (if
this thing does IPP), or use whatever port the thing uses.
