HP JetDirect card - assigning a fixed IP

U

Usual Suspect

JetDirect card J3111A/600N (10baseT, RJ-45).

Logging into the card using a web browser, under Configurations tab, the TCP
options can be found. One of the choices is to choose whether the IP address
is assigned via DHCP, BOOTP, or Manually.

From the drop-down menu I choose Manually and then click the Apply button at
the bottom of the window. (I left the IP address alone as it was fine; I just
want it to remain that address and not get reassigned by DHCP.)

When the window refreshed, the drop-down menu said "DHCP". I repeated the
selection of Manual from the menu and again clicked the Apply button, but
again, when the window refreshed the menu showed DHCP.

I shut off the printer and restarted it; it showed the same IP address, but
I'm not sure if it is showing me its fixed address, or it's just that the
DHCP router had assigned the same dynamic address to the printer.

Has anyone come across this problem with JetDirect cards? Did I set a fixed
address? Will it remain the same? If not, how does one get around the problem
of the menu reverting to DHCP?

Thanks,

You should not configure a static address within the range supplied
by DHCP. It should, then, not configure using DHCP the same address
set as a static address.

Ah, I think I see your point. DHCP router will assign addresses within a
range defined by (me?). I can assign static addresses outside this range.

But the JD card won't "know" what those dynamic addresses are. And the router
will poll and see that that address is already taken, so it will not dole it
out. Isn't this correct?

A better way would be to configure your DHCP server to always assign
that IP address to the JetDirect's MAC address.
When the window refreshed, the drop-down menu said "DHCP". I repeated the
selection of Manual from the menu and again clicked the Apply button, but
again, when the window refreshed the menu showed DHCP.

Maybe a web browser artifact. Telnet to the printer and use the text
menus if you want fast, simple, and clear instead of pointy-clicky
ambiguity.

Print a self-test page and it should show the current configuration of
the JetDirect.

DHCP won't poll and will likely give that address to the next host
that makes a request.

Some hosts, when starting up, ARP for their address and complain
if a reply comes back (from someone else using that address).
I don't know that any do that for DHCP assigned addresses.

There is no poll method, and I don't know any DHCP servers
that use ARP to test addresses.

This is a nice way to do things.

But you do, and you're the one who assigns the JetDirect a static
address.

DHCP is supposed to ping an address before reusing it. However, that
only works if you leave the JetDirect powered on all the time. Or,
technically, at least powered on when a new DHCP lease is needed.

The DHCP ping check might not be implemented by cheap routers, or might
have been disabled by someone who thought that was a good idea--great
fun on a big network.

I just set up some of these cards Friday and updated my network to make
sure that everything allows pings so my dhcp server will (hoopefully)
see addresses that are in use. I have some legacy addresses that are in
the dhcp assigned range but on fixed laserjet ip. Since it is a
Microsoft dhcp server, I also set those specific adr to be excluded from
dhcp, but before I did that, IF ping was working, dhcp did not use that
adr. I set ip my jetdir card with the web interface, choose manual,
entered the ip adr, then a few lines down had to enter or confirm the
snmp "password", which would be "public" if another one was not used.
This then allowed the changes and saved it.

I use the old Mac OS9 HP Control Panel to set IP addresses....

Can you provide a link to that app?

You could always use the HP LaserJet Utility to set the address. I do.
It runs under Classic and is available at

As a last resort. you can always set the IP address and mask via the
buttons on the panel.

And the version above appears to be an older version than what I have
running on my Mac.

I'm sure I have a copy lying around but who has OS 9 connected to the network in question?

FTP into the printer is what I used when the web support was "odd". Which was more often than not.
