network printer static IP

That is rather odd since arp -a should not only return
the IP address of your router but also the machine on
which you are running the command.

My squeeze returns only non-local devices with which my local host
has communicated (recently).

Run the following as root, and it will give you the devices on your
local network that are running a web server. Since your printer includes
a web server you should be able to see it listed:

aptitude install nmap
NET=`netstat -rn | awk '$4~/G/{print $2}' | cut -d. -f1-3`.0
nmap -oG - -p 80 $NET/24 | grep /open/


I've used aptitude but you're welcome to use your preferred package
installer. The NET= line is there to derive your local /24 network
(e.g. 192.168.1.0). If you know it, simply substitute into the nmap
command.

So have you ever actually printed anything from a machine
on the LAN to the printer via ethernet or WiFi?

Who installed the printer and setup its network
connections?

Ah, the light is beginning to shine! At this point, there is only one
machine on the LAN, and I print with it all the time. However, the
printer is connected by USB, not by ethernet CAT5; there's no ethernet
jack on the printer.

I suspect I need to add a Jetdirect print server to my LJ1320 printer, I
contacted HP and they pointed me to the HP Jetdirect 300x Print Server
for Fast Ethernet. It's compatible with RedHat 7 and SUSE 8, and so I
suppose it will work with my Debian squeeze. It has a DB-25 parallel
connector for the printer and a RJ-45 to connect to my router hub. My
printer is DB-36, so I suppose that all I need is a suitable cable to do
the pin conversion.

Am I off base here?

Chris,

Since my printer is USB connected, I suppose the nmap return will not be
informative. But here it is anyway:

# nmap NET=`netstat -rn | awk '$4~/G/{print $2}' | cut -d. -f1-3` .0

If the printer is USB connected and not ethernet connected
to the LAN, how do you ever hope to see it as a "host" on
the LAN with a network utility or for it to be assigned an
IP address by your router DHCP server?
