HP
Jetdirect Print Servers - Host Name Troubleshooting

ISSUE:

Why do print jobs fail when printing to the
host name?

SOLUTION:

Name resolution may not be configured or may
not be functioning on the network. Also, the HP Jetdirect may not
have the correct host name or IP address. First, print a Jetdirect
Configuration page to determine the IP address, hostname, and also
to look for any error messages.

Printing a Jetdirect Configuration page

Below are general steps for printing a
Configuration page. Click
here for more specific steps for specific printers. The host
name is in the TCP/IP section of the Configuration page. Verify that
the correct host name is on the Jetdirect Configuration page.

Most HP printers with an internal HP Jetdirect
print server can print a configuration page by using the front panel
of the printer.

Internal HP Jetdirect Print Servers

Press the MENU
button on the front panel of the printer to go to the Information, Test,
or PCL Test menu.

Press the ITEM
button to go to the Print Configuration,
Print EIO Configuration, PCL Configuration Page, or the Self Test.

Press the SELECT
the button to print the page

Plotters vary even more. Their configuration
pages are usually found under the Utilities menu and are
called Service, Print Service Config, or Config
Plot. Press ENTER to print.

The HP LaserJet 2100 printer will print its
page after pressing both buttons on top of the printer
simultaneously.

External HP Print Servers

External HP Jetdirect servers have a TEST
button on the top or on the back of the HP Jetdirect
server.

Press the TEST button.

Steps for testing and troubleshooting the
host name

Ping the host name of the HP
Jetdirect. If there is no reply, the server providing the name
resolution is not configured properly or is not functioning, or
the HP Jetdirect is not on the network.

If there is a reply to the ping, telnet to
the host name to verify a connection at the application
layer.

Ping the IP address of the HP
Jetdirect. Usually, the host name will appear in the reply.

Verify that the host
name that is shown in the reply to the ping is the same as
the host name used for printing.

Verify that the correct host
name is on the Jetdirect Configuration page.

Verify that the IP
address used in the ping is the same IP address that is
printed on the Jetdirect Configuration page (usually, the ping
reply will contain the IP address of the device that is
responding, although the IP address of a router or name server
may also appear).

At a command prompt, use the nslookup
command to verify the IP address and host name. Type the following
command:

nslookup IP address.

The correct name and IP address should
appear.

Troubleshooting for a UNIX operating
system

Type the following command:

grep IP address /etc/hosts

Example:

grep 15.39.112.94 /etc/hosts

If the /etc/hosts entry is correct, this
command should return one line. For example: 198.39.112.94 hpb12348
hpb12348#John Doe X5575 VECTRA [no SMTP]

grep "the host-name" /etc/hosts

Example:

grep hpb13468 /etc/hosts

If the /etc/hosts entry is correct,
this command should return one line. For example:

198.39.112.94 hpb12348 hpb12348#John Doe X5575
VECTRA [no SMTP]

If either of these commands returns something
other than one line, there is a duplication in /etc/hosts
that must be resolved by the network administrator. Incorrect lines
in /etc/hosts may be commented out by putting a pound sign
(#) in front of the line(s). A correct /etc/hosts entry shows
the IP address and the host name on the same line.

Changing the host name on the HP
Jetdirect

On many Jetdirects, the host name can be
changed using telnet.

Telnet to the IP address of the Jetdirect.
For example:

Telnet 192.168.192.191.

Press ENTER twice
to be sure there is a connection, then type a forward slash (/), and press ENTER
to see Jetdirect information.

Depending on the Jetdirect firmware, local
echo must be turned on or off in telnet. This is found under
Terminal and Preferences in the Telnet window,
except in Windows 2000.

Telnet in Windows 2000

Click Start then click
Run.

Type telnet, and
press ENTER.

Type: SET
LOCAL_ECHO. (Some devices, such as a Jetdirect 610n card,
do not need local echo set. If local echo is set and double sets
of characters appear when using telnet, exit telnet and start
over, then type UNSET LOCAL_ECHO.

Type: open
ipaddress (for example, open
192.168.192.191).

Once in telnet, type the following command
to change the host name. Example: host-name:
MY_PRINTER

Some HP Jetdirects have a telnet menu. In
telnet, type menu The host name is found
under TCP/IP Menu, and then under TCP/IP Main
Settings.

Type quit or
select Exit in the Menu system to save the change and exit
Telnet
