Introduction

The network administrator or the user is
responsible for deciding what the TCP/IP address should be assigned
to any given print server. In doing so, there are several steps to
consider:

How to determine the current TCP/IP address of the HP
Jetdirect

If necessary, how to reset the HP Jetdirect to factory default
settings

Which method to use to configure the TCP/IP address on the HP
Jetdirect

Printing a Configuration page to determine
the TCP/IP address of the HP Jetdirect

The current TCP/IP address as
well as the status of the HP Jetdirect can be viewed on its
Configuration page. Print a Configuration page by using the
printer's control panel Information menu or by using the
Test button of an external or an LIO HP Jetdirect print
server. Click
here for additional steps to print a Configuration page (as
well as how to reset the HP Jetdirect to factory defaults which is
described below). It is recommended to print a Configuration page
after configuring the HP Jetdirect to verify that the correct
TCP/IP address and other information is correct.

Resetting the HP Jetdirect to factory default
settings

Click
here for detailed instructions on how to reset your HP Jetdirect
Print Server.

Also known as a cold
reset, a cold reset can be helpful if unable to Telnet to the
print server due to an IP address conflict or if unable to see it
in HP Web Jetadmin, the Install Network Printer Wizard, or one of
the other utilities listed below. A cold reset will clear any
previous IP address or passwords as well as resetting the printer
configuration back to factory defaults. Here are some general
steps that work for most printers and print servers. Additional
cold reset steps may be found in the printer's manual or CD-ROM
documents or on the HP Web site noted in the hyperlink above.

Most HP printers with
internal HP Jetdirect print servers can be reset to factory
defaults (or cold-reset) by turning the printer off and holding
down the ONLINE or GO buttons while turning the printer back on.
The printer's control panel display should read Cold Reset or Restoring
Factory Settings. If the printer has no LCD display, the
indicator lights will cycle.

To cold reset an LIO print
server (such as the 250M or 200M), remove the print server from
the printer, press an hold the test button while putting the
print server back into the printer. Continue to hold the test
button for about five seconds.

To cold reset an HP
Jetdirect external print server, unplug the power cord from the
HP Jetdirect print server, then hold down the TEST button (on
top of or in back of the HP Jetdirect) for five to 30 seconds
while plugging in the power cord.

Methods to configure the TCP/IP address of
the HP Jetdirect

Several methods to configure a
TCP/IP address will be described below. Briefly, these methods
include:

Using HP software (see the sections below for details), such
as the following:

HP Web Jetadmin

Install Network Printer Wizard (INPW)

HP Jetdirect Printer Installer for UNIX

Using a Web browser to use the HP Jetdirect print server's
embedded Web server

Using the control panel of a printer or plotter

Using Telnet from a computer

Using a BootP or DHCP server

Using Arp -s and Ping from a computer

The following sections
described the steps to configure the TCP/IP address of the HP
Jetdirect using these various methods.

HP Web Jetadmin 7.x

Click here to
download the latest version of HP Web Jetadmin.

Open HP Web Jetadmin
7.x

If the TCP/IP address is
already configured on the HP Jetdirect print server and needs to
be changed, enter the TCP/IP address in Quick Device Find, and
click GO. Skip to Step 6.

For new HP Jetdirect print
servers that have not been configured with a TCP/IP address,
proceed to Step 3.

From the Navigation box,
select Device Management.

Expand the Device
Management folder.

Expand the Device
Lists folder.

Highlight New
Devices.

Click the column header of
your choice, such as IP Address or Device
Model. Arrange the list by ascending or descending
order.

Highlight the printer to be
configured.

From the Device Tools
drop-down menu, select Open Device.

From the drop-down menu at
the top, select Configuration.

Under Configuration
Categories located on the top left side, Click
Network.

Enter the IP information.
You may scroll down for more options.

Click Apply to save
the settings.

Click the Refresh
icon located on the top right of the screen.

Verify the IP information by
doing the following:

Print a Configuration page
from the printer's front panel.

Select Status from
the drop-down menu.

Select Diagnostics
from the drop-down menu.

HP Jetdirect Printer Installer for
UNIX

The HP Jetdirect Printer
Installer for UNIX can assign a TCP/IP address by either creating
a BootP entry on the BootP server or by opening a telnet
connection to the HP Jetdirect and configuring it directly. Below
are the steps for both.

Click here to download the HP
Jetdirect Printer Installer for UNIX.

Using a BOOTP Configuration
for new, unconfigured HP Jetdirects

Login as root, and run
hppi (found in the /opt/hpnpl directory).

Select Jetdirect
Configuration (super-user only).

Select Create Printer
Configuration in BOOTP/TFTP database.

The software will prompt for
the HP Jetdirect LAN hardware address (This can be found on the
configuration page of the printer or the external HP
Jetdirect).

Follow the steps on screen
to assign a hostname and a TCP/IP address for the HP Jetdirect
print server. The TCP/IP address must be correct for the
network.

Configure the remainder of
the optional parameters as necessary. Typically, the important
ones to note are Subnetmask, Gateway, and Banner Page.

Type a zero to configure the
BOOTP/TFTP entry.

Turn on the HP Jetdirect print server (or turn it off and
back on) or cold reset the printer/Jetdirect. When the HP
Jetdirect boots up, it will broadcast BootP requests and receive
the TCP/IP address form the BootP server.

Using a Telnet
Connection

Login as root, and run
hppi (found in the /opt/hpnpl directory).

Select Jetdirect
Configuration (super-user only)

Do one of the
following:

Select Set IP Address
locally. Use this for unconfigured HP Jetdirect print
servers.

Select Open Telnet
Session to Jetdirect Card. Use this for HP Jetdirect print
servers that are already configured.

If Option 4 is selected,
enter the HP Jetdirect LAN hardware address. This can be found
on the configuration page of the printer or the external HP
Jetdirect. If Option 5 is selected, enter the hostname or IP
address of the HP Jetdirect print server.

Follow the steps on screen
to enter the TCP/IP address, and finish the
configuration.

Using the Embedded Web server

HP Jetdirect print servers
with firmware x.07.03 or later has an embedded Web server that can
be used to modify the TCP/IP parameters. However, to use the
embedded Web server, the HP Jetdirect print server must have an IP
address already configured.

Using a supported Web
browser, enter the IP address of the HP Jetdirect print server
as the URL.

The HP Jetdirect main Web
page will be displayed. Click Networking, Network
Settings, and then TCP/IP or click
Administration and then Configuration. From
this page, it is possible to modify the TCP/IP addresses and the
set community name.

Using Telnet

Using Telnet to configure an
HP Jetdirect print server will configure it with a static TCP/IP
address and keeps the print server from querying a BootP or DHCP
server for a dynamic IP address. Most HP Jetdirect print servers
support Telnet; the minimum firmware version of the HP Jetdirect
must be A.03.03 or a letter/number combination greater. The
exception to this is the HP Jetdirect 150x, which does not have a
TCP/IP protocol stack at all.

Before using Telnet

If the TCP/IP address is
already configured on the HP Jetdirect print server and needs to
be changed, skip to Step 1, and use that TCP/IP address in
Telnet.

Most HP Jetdirect print
servers have a default IP address of either 192.0.0.192 or
169.254.x.x. Print a configuration page as described at the
beginning of this document, check the TCP/IP status and address,
and make sure that the I/O card status reads, Ready.

If other HP Jetdirect print
servers are on the network with this default IP address, they must
be turned off before using Telnet because it is possible that
Telnet will fail to connect to the HP Jetdirect or, if it does
connect, inadvertently configure the wrong print server.

In most networks, it might be
necessary to use a Route Add command to resolve this default
address on the computer. For a UNIX operating system, use a man
command for route add. For most operating systems, the route add
command is (using the example HP Jetdirect IP address of
192.0.0.192): route add 192.0.0.192
IPaddress_of_computer For example:

route add
192.0.0.192 198.10.9.8

NOTE: See the help files or man
pages of the operating system for more ways to use route add
(for example, how to add the subnet and hop count).

To display and verify that the
192.0.0.192 address in the route table, use the command: netstat -rn

Click
here for instructions on using Telnet with other operating
systems.

After the route add command,
it should be possible to Telnet to 192.0.0.192. In the Telnet
session, follow these directions:

At a DOS or command prompt
type telnet 192.0.0.192. In Windows
2000, type telnet, then, press Enter

Type SET
LOCAL_ECHO

Type open
ipaddress (for example: open
198.164.222.222)

Press ENTER twice.

Type a question mark (?) to
display a list of the available commands used for configuring
the HP Jetdirect print server. Type a forward slash (/) to see
the current settings on the print server. Print servers with
firmware before x.05.05 only need a question mark (?) to display
a list of commands and the current settings.

Using the list of commands
displayed, make the desired changes.

Type quit to exit and save changes (type exitto exit Telnet without saving
changes).

Front panel of printer

Click
here to configure your IP address using the control panel of a
LaserJet or Business Inkjet.

Click
here to configure your IP address using the control panel of a
Designjet.

The IP address may also be
changed using the front panel of the HP Jetdirect device. This
method of front panel configuration varies greatly depending on
the model of HP printer that is being used (consult the User's
Guide for the front panel instructions for a particular
printer). Click here to go to the HP
Web site. Use the Search and search for Front
Control Panel TCP/IP Configuration.

Bootstrap Protocol (BootP)

When the printer is turned on,
the HP Jetdirect print server broadcasts BootP requests. BootP is
a bootstrap protocol used to automatically download an IP address
and other TCP/IP parameters from a network server. The computer
with the proper BootP configuration sends the TCP/IP information
to the HP Jetdirect print server. Consult the documentation of the
particular operating system to set up BootP on the
computer.

Dynamic Host Configuration Protocol
(DHCP)

When the printer is turned on,
the HP Jetdirect print server also broadcasts DHCP requests. DHCP
is similar to BootP in that it automatically downloads an IP
address from a network server. However, DHCP servers maintain a
fixed set of IP addresses and only loan an IP address to the print
server. Whenever the printer is turned off and on, there is no
guarantee that an HP Jetdirect print server will be assigned the
same IP address over time, although the DHCP server will attempt
to do so. Consult the documentation of the particular operating
system to set up DHCP on the computer.

ARP -s TCP/IP configuration

This functionality allows an
administrator to quickly configure HP Jetdirect cards without
waiting for the default IP address. This applies to HP
Jetdirect cards with firmware of x.08.03 and later only. With
this firmware, the HP Jetdirect is able to glean an IP address
from a ping packet only while it is initializing . With
firmware revision x.20.24 or greater, the HP Jetdirect will glean
an IP address only when it is at the default IP
address.

The following shows two
examples of commands that you would type to configuring the TCP/IP
address using ARP -s:

Example 1 (for Microsoft
Windows):

ARP -s
10.1.2.3 08-00-09-12-34-56

ping
10.1.2.3

Example 2 (for UNIX):

ARP -s
10.1.2.3 08:00:09:12:34:56

ping
10.1.2.3

apr -d 10.1.2.3

These examples will cause an
HP Jetdirect card with a MAC address of 080009123456 to glean the
IP address, 10.1.2.3.

The Configuration page for the
HP Jetdirect configured by this method would be as follows:

Parameter

Description

Host name

Not specified

Config by

User specified

IP address

10.1.2.3

Subnet mask

Not specified

Def. gateway

10.1.2.3

HP Jetdirect cards will not
accept an ARP -s configuration over routers. When a router routs a
packet, the destination MAC address is the MAC address of the
router and not the address of the HP Jetdirect. As a result, the
HP Jetdirect will never receive the ICMP echo request packet
unless it is on the same routed segment as the client workstation
that is attempting to configure it.

NOTE: HP recommends that the static
arp table entry be removed after the HP Jetdirect obtains the
TCP/IP address information. Deleting the static arp table entry
can be done by typing arp -d
ip_address_used_in_arp -s
