1 Introducing the HP Jetdirect Print
Server
HP Color LaserJet 3600n/dn printers contain an HP Jetdirect embedded print server that is
integrated directly on the printer. Using this print server, you can connect this device directly to a
network and share it among multiple users or systems. Because the print server is built into the
device, an external port is not needed for network connectivity and may be used for other purposes.
Network Connection
Using the embedded print server and built-in RJ-45 connector, the printer can connect to an IEEE
802.3 10/100Base-TX (Ethernet/Fast Ethernet) network through unshielded twisted-pair network
cables.
Auto-negotiation (10/100Base-TX) is used to automatically configure link operation at 10 Mbps or
100 Mbps, and full- or half-duplex communication mode, as required by the network. However, link
operation may be manually set using several configuration tools, such as the printer control panel (if
supported), Telnet and TFTP commands, a Web browser, and network management software.
These tools are described later in this guide.
NOTE Unless otherwise specified, the term print server in this manual refers to an HP
Jetdirect print server and not a separate computer running print server software.
Identification
Product Number and Firmware Version
The features and capabilities of an HP Jetdirect print server depends on the print server's product
model number and its operating firmware version. The print server in this printer does not support
firmware upgrades.
The product model number and operating firmware version are listed on the HP Jetdirect
configuration page. The HP Jetdirect configuration page will print when you print the printer's
configuration page.
The features and capabilities described in this guide support the following HP Jetdirect print server

8 Chapter 2 HP Software Solutions Summary ENWW
3 TCP/IP Configuration
To operate properly on a TCP/IP network, the HP Jetdirect print server must be configured with valid
TCP/IP network configuration parameters, such as an IP address that is valid for your network. For
general information on TCP/IP networks, see
Server-Based and Manual TCP/IP Configuration
When in a factory-default state and initially powered on, the HP Jetdirect print server will
systematically try to obtain its TCP/IP configuration using a server-based method (BOOTP, DHCP,
and RARP, described later in this chapter). Up to two minutes are used. If configuration is not
successful, a default IP address will be assigned.
The print server may also be configured manually. Manual-based tools include Telnet, a Web
browser, the printer control panel, arp and ping commands (when the default IP address is
192.0.0.192), or SNMP-based management software. TCP/IP configuration values assigned
manually will be retained when powered off/on.
TCP/IP Overview.
The print server can be re-configured to use either server-based or manual configuration of TCP/IP
settings at any time.
To identify the IP address that is configured on the print server at any time, see the HP Jetdirect
configuration page.
Default IP Address
When in a factory-default state (for example, when shipped from the factory or after a cold reset), the
HP Jetdirect print server has no IP address. A default IP address may or may not be assigned
depending on the network environment.
Default IP Address Will Not Be Assigned
A default IP address will not be assigned if a server-based method (such as BOOTP or DHCP) is
successful. And if the print server is powered off/on, the same method will again be used to retrieve
IP configuration settings. If this method now fails to retrieve the IP configuration settings (for
example, the BOOTP or DHCP server is no longer available), a default IP address will not be
assigned. Instead, the print server will continue to send IP configuration requests indefinitely. You
must cold-reset the print server to change this behavior.
In addition, a default IP address will not be assigned if a network cable is not attached to the print
server.
ENWW Server-Based and Manual TCP/IP Configuration 9
Default IP Address Will Be Assigned
A default IP address will be assigned if the factory-default methods fail, or if the print server has just
been re-configured by an administrator to use a server-based method (such as BOOTP or DHCP)
and it fails.
If a default IP address is assigned, the address will depend on the network to which the print server
is connected. The print server senses broadcast packets on the network to determine the appropriate
default IP settings:
■ On small private networks that adhere to automated, standards-based IP address assignments,
the print server uses a link-local addressing technique to assign a unique IP address. Link-local
addressing may be referenced as Auto IP. The IP address assigned will be in the range of
169.254.1.0 to 169.254.254.255 (commonly referenced as 169.254/16), and should be valid.
However, it can be further modified for your network using supported TCP/IP configuration tools
if necessary.
With link-local addresses, subnetting is not used. The subnet mask will be 255.255.0.0, and
cannot be changed.
Link-local addresses will not route off the local link, and access to or from the Internet will not be
available. The default gateway address will be the same as the link-local address.
If a duplicate address is sensed, the HP Jetdirect print server will automatically reassign its
address, if necessary, in accordance with standard link-local addressing methods.
■ On large or enterprise IP networks, a temporary address of 192.0.0.192 will be assigned until it is
re-configured with a valid address through supported TCP/IP configuration tools. We refer to this
address as Legacy Default IP.
■ On mixed-environment networks, the self-assigned default IP address may be either 169.254/16
or 192.0.0.192. In this case, you should verify on the Jetdirect configuration page that the
assigned default IP address is as expected.
The IP address configured on your print server may be determined by inspecting the Jetdirect
configuration page for the print server. See
HP Jetdirect Configuration Page.
Default IP Address Configuration Options
Default IP Parameter Options
A Default IP configuration parameter on the print server controls how the default IP address is
assigned. Whenever the print server is unable to obtain an IP address during a forced TCP/IP reconfiguration (for example, when manually configured to use BOOTP or DHCP), this parameter will
determine the default IP address to use.
When the print server is in a factory-default state, this parameter is undefined.
If the print server is initially configured with a default IP address (either a link-local IP address or the
legacy default 192.0.0.192 IP address), the Default IP parameter will be set to either Auto IP or
Legacy Default IP to match.
The Default IP parameter can be changed through a supported configuration tool, such as Telnet, a
Web browser, the printer control panel, and SNMP management applications.
10 Chapter 3 TCP/IP Configuration ENWW
DHCP Requests Enable/Disable
When a default IP address is assigned, you can choose to send, or not send, periodic DHCP
requests. DHCP requests are used to retrieve IP configuration settings from a DHCP server on the
network. By default, this parameter is enabled, allowing DHCP requests to be transmitted. However,
this parameter may be disabled through supported configuration tools such as Telnet, a Web
browser, and SNMP management applications.
TCP/IP Configuration Tools
Depending on your printer and operating system, an HP Jetdirect print server can be configured with
valid TCP/IP parameters for your network in the following ways:
■ Using Software. You can use your printer installation software on supported systems. For more
information see
■ BOOTP/TFTP. You can download the data from a network-based server using BOOTP
(Bootstrap Protocol) and TFTP (Trivial File Transfer Protocol) each time the printer is turned on.
For more information, see
The BOOTP daemon, bootpd, must be running on a BOOTP server that is accessible by the
printer.
■ DHCP/TFTP. You can use Dynamic Host Configuration Protocol (DHCP) and TFTP (Trivial File
Transfer Protocol) each time the printer is turned on. These protocols are supported on HP-UX,
Solaris, Linux, Windows NT/2000/Server 2003, NetWare and Mac OS systems. (Refer to your
network operating system manuals to verify that your server operating system supports DHCP.)
For more information, see
HP Software Solutions Summary.
Using BOOTP/TFTP.
Using DHCP.
NOTE Linux and UNIX systems: For more information, see the bootpd man page.
On HP-UX systems, a sample DHCP configuration file (dhcptab) may be located in the /
etc directory.
Since HP-UX presently does not provide Dynamic Domain Name Services (DDNS) for its
DHCP implementations, HP recommends that you set all print server lease durations to
infinite. This ensures that print server IP addresses remain static until such time as
Dynamic Domain Name Services are provided.
■ RARP. A network-based server can use RARP (Reverse Address Resolution Protocol) to
answer the print server's RARP request and supplying the print server with the IP address. The
RARP method only allows you to configure the IP address. For more information, see
■ arp and ping commands. (For print servers configured with Legacy default IP address
192.0.0.192 only) You can use the arp and ping commands from your system. For more
information, see
■ Telnet. You can set configuration parameters using Telnet. In order to set configuration
parameters, set up a Telnet connection from your system to the HP Jetdirect print server using
the default IP address. Once configured, the print server saves the configuration when powered
off/on. For more information, see
■ Embedded Web server. You can browse to the embedded Web server on the HP Jetdirect print
server to set the configuration parameters. For more information, see
Server.
Using the arp and ping Commands.
Using Telnet.
Using the Embedded Web
Using RARP.
ENWW Default IP Address 11
■ Printer Control Panel. You can manually enter the configuration data using the printer control
panel keys. The control panel method allows you to configure only a limited subset of
configuration parameters. Therefore, control panel configuration is recommended only during
troubleshooting or for simple installations. If control panel configuration is used, the print server
saves the configuration when powered off/on. For more information, see
Control Panel.
Using BOOTP/TFTP
BOOTP (Bootstrap Protocol) and TFTP (Trivial File Transfer Protocol) provide a convenient way to
automatically configure the HP Jetdirect print server for TCP/IP network operation. When powered
on, the Jetdirect print server sends a BOOTP request message onto the network. A properly
configured BOOTP server on the network will respond with a message that contains basic network
configuration data for the Jetdirect print server. The BOOTP server's response may also identify a file
that contains extended configuration data for the print server. The Jetdirect print server downloads
this file using TFTP. This TFTP configuration file may be located on the BOOTP server, or a
separate TFTP server.
BOOTP/TFTP servers are typically UNIX or Linux systems. Windows NT/2000/Server 2003 and
NetWare servers can respond to BOOTP requests. Windows NT/2000/Server 2003 servers are
configured through Microsoft DHCP services (see
2003 systems may require third-party software for TFTP support. For setup of NetWare BOOTP
servers, refer to your NetWare documentation.
Using the Printer
Using DHCP). However, Windows NT/2000/Server
NOTE If the Jetdirect print server and BOOTP/DHCP server are located on different
subnets, IP configuration may fail unless the routing device supports “BOOTP Relay” (allows
the transfer of BOOTP requests between subnets).
NOTE While the print server may be configured from systems that support BOOTP/DHCP
services, this printer may not support printing from these systems (such as UNIX or NetWare
systems).
Why Use BOOTP/TFTP?
Using BOOTP/TFTP to download configuration data has the following benefits:
■ Enhanced configuration control of the HP Jetdirect print server. Configuration by other methods,
such as a printer control panel, are limited to select parameters.
■ Ease of configuration management. Network configuration parameters for the entire network can
be in one location.
■ Ease of HP Jetdirect print server configuration. Complete network configuration can be
automatically downloaded each time the print server is powered on.
NOTE BOOTP operation is similar to DHCP, but the resulting IP parameters will be the
same when powered off/on. In DHCP, IP configuration parameters are leased and may
change over time.
When in its factory-default state and powered on, the HP Jetdirect print server will attempt to
automatically configure itself using several dynamic methods, one of which is BOOTP.
12 Chapter 3 TCP/IP Configuration ENWW
BOOTP/TFTP on UNIX
This section describes how to configure the print server using BOOTP (Bootstrap Protocol) and
TFTP (Trivial File Transfer Protocol) services on UNIX servers. BOOTP and TFTP are used to
download network configuration data from a server to the HP Jetdirect print server over the network.
Systems That Use Network Information Service (NIS)
If your system uses NIS, you may need to rebuild the NIS map with the BOOTP service before
performing the BOOTP configuration steps. Refer to your system documentation.
Configuring the BOOTP Server
For the HP Jetdirect print server to obtain its configuration data over the network, the BOOTP/TFTP
servers must be set up with the appropriate configuration files. BOOTP is used by the print server to
obtain entries in the /etc/bootptab file on a BOOTP server, while TFTP is used to obtain
additional configuration information from a configuration file on a TFTP server.
When the HP Jetdirect print server is powered on, it broadcasts a BOOTP request that contains its
MAC (hardware) address. A BOOTP server daemon searches the /etc/bootptab file for a
matching MAC address, and if successful, sends the corresponding configuration data to the
Jetdirect print server as a BOOTP reply. The configuration data in the /etc/bootptab file must be
properly entered. For a description of entries, see
The BOOTP reply may contain the name of a configuration file containing enhanced configuration
parameters. If the HP Jetdirect print server finds such a file, it will use TFTP to download the file and
configure itself with these parameters. For a description of entries, see
Entries. Configuration parameters retrieved through TFTP are optional.
Bootptab File Entries.
TFTP Configuration File
NOTE HP recommends that the BOOTP server be located on the same subnet as the
printers it serves. BOOTP broadcast packets may not be forwarded by routers unless the
routers are properly configured.

more information, see
syslog-max:
■ Specifies the maximum number of syslog messages that can be sent by the HP Jetdirect print server on a per-minute
basis. This setting allows administrators to control the log file size. The default is 10 per minute. If it's set to zero, the
number of syslog messages is not restricted.
syslog-priority:
■ Controls the filtering of syslog messages sent to the syslog server. The filter range is 0 to 8, with 0 being the most
specific and 8 the most general. Only messages that are lower than the filter level specified (or higher in priority) are
reported. The default is 8, messages of all priorities are sent. If 0, all syslog messages are disabled.
syslog-facility:
■ A code used to identify the source facility of a message (for example, to identify the source of selected messages during
troubleshooting). By default, the HP Jetdirect print server uses LPR as the source facility code, but local user values of
local0 through local7 can be used to isolate individual or groups of print servers.
slp-config:
■
Enables or disables the Service Location Protocol (SLP) operation on the print server: 0 disables, 1 (default) enables.
slp-keep-alive:
TCP/IP Overview.
■ Specifies a time period for the print server to send multicast packets on the network to prevent being deleted from
network device tables. Some infrastructure devices, such as switches, may delete active devices from their device
tables due to inactivity on the network. To enable this feature, set a value from 1 to 1440 minutes. Set 0 to disable this
feature.
ttl-slp:
■ Specifies the IP multicast “Time To Live” (TTL) setting for Service Location Protocol (SLP) packets. The default value is

■ Enables or disables the receipt and transmission of IP version 4 multicast packets by the print server. 0 disables, 1
(default) enables.
NOTE If this parameter is disabled, other protocols that use multicast protocols, such as mDNS and SLP, may
also be disabled without notification.
idle-timeout:
■ The number of seconds that an idle print data connection is allowed to remain open. Since the card supports only a
single TCP connection, the idle timeout balances the opportunity of a host to recover or complete a print job against the
ability of other hosts to access the printer. The acceptable values range from 0 to 3600 (1 hour). If “0” is typed, the
timeout mechanism is disabled. The default is 270 seconds.
user-timeout: (or telnet-timeout:)
■ An integer (1..3600) that specifies the number of seconds that your Telnet or FTP session can be idle before it will be
automatically disconnected. The default is 900 seconds. 0 disables the timeout.
CAUTION Small values, such as 1–5, may effectively disable the use of Telnet. A Telnet session may
terminate before any changes can be made.
ews-config: (or web:)
■
Enables or disables the print server's embedded Web server to change configuration values: 0 disables, 1 (default)
enables.
tcp-mss: (or subnets-local:)
■ Specifies the maximum segment size (MSS) that the HP Jetdirect print server will advertise for use when
communicating with local subnets (Ethernet MSS=1460 bytes or more) or remote subnets (MSS=536 bytes):
0 (default): All networks are assumed to be local (Ethernet MSS=1460 bytes or more).
1: Use MSS=1460 bytes (or more) for subnets, and MSS=536 bytes for remote networks.
2: All networks are assumed to be remote (MSS=536 bytes), except the local subnet.
MSS affects performance by helping to prevent IP fragmentation that may result in data retransmission.
20 Chapter 3 TCP/IP Configuration ENWW
Table 3-2 TFTP Configuration File Parameters (continued)
tcp-msl:
■ Specifies the maximum segment life (MSL) in seconds. The range is 5–120 seconds. The default is 15 seconds.
telnet-config: (or telnet:)
■ If set to 0, this parameter instructs the print server not to allow incoming Telnet connections. To regain access, change
the setting in the TFTP configuration file and power cycle the print server, or cold reset the print server to factory default
values. If this parameter is set to 1, incoming Telnet connections are allowed.
default-ip:
■ Specifies the IP address to use when the print server is unable to obtain an IP address from the network during a forced
TCP/IP reconfiguration (for example, when powered off/on or manually configured to use BOOTP/DHCP).
DEFAULT_IP: sets the legacy default IP address 192.0.0.192.
AUTO_IP: sets a link-local IP address 169.254.x.x.
The initial setting is determined by the IP address obtained when first powered on.
default-ip-dhcp:
■ Specifies whether DHCP requests will be periodically transmitted when a legacy default IP address 192.0.0.192 or link-
local IP address 169.254.x.x has been automatically assigned.
0: Disables DHCP requests.
1 (default): Enables DHCP requests.
dhcp-arbitration:
■ Specifies the amount of time, in seconds, that the print server will wait for DHCP configuration offers. A value from 1 to
10 may be set. The default is 5 seconds.
phone-home-config:
■ Specifies privacy settings on the print server during embedded Web server access. This command controls whether
statistical data on product use may be sent to HP. For HP to collect data, Internet access is required.
2: Prompt the user to allow sending data on initial access to the Networking tab of the embedded Web server. This is
the factory-default and cold-reset value. Once changed, this value cannot be re-selected.
1: Allows the sending of data to HP without prompting the user.
0: Disables sending data to HP without prompting the user.
web-refresh:
■ Specifies the time interval (1–99999 seconds) for embedded Web server diagnostic page updates. If set to 0, the
refresh rate is disabled.
SNMP
snmp-config:
■ Enables or disables SNMP operation on the print server. 0 disables, 1 (default) enables SNMP.
CAUTION Disabling SNMP will disable all SNMP agents (SNMP v1, v2c) as well as communications with HP
Web Jetadmin. In addition, firmware upgrades through current HP downloading utilities will be disabled.
ENWW Using BOOTP/TFTP 21
Table 3-2 TFTP Configuration File Parameters (continued)
get-cmnty-name: (or get-community-name:)
■ Specifies a password that determines which SNMP GetRequests the HP Jetdirect print server will respond to. This is
optional. If a user-specified get community name is set, the print server will respond to either a user-specified
community name or the factory-default. The community name must be ASCII characters. The maximum length is 255
characters.
set-cmnty-name: (or set-community-name:)
■ Specifies a password that determines which SNMP SetRequests (control functions) the HP Jetdirect print server will
respond to. The community name of an incoming SNMP SetRequest must match the print server's “set community
name” for the print server to respond. (For additional security, you may limit configuration access through the print
server's host access list). Community names must be ASCII characters. The maximum length is 255 characters.
auth-trap: (or authentication-trap:)
■ Configures the print server to send (on) or not send (off) SNMP authentication traps. Authentication traps indicate that
an SNMP request was received, but the community name check failed. The default is “on.”
trap-dest: (or trap-destination:)
■
Enters a host's IP address into the HP Jetdirect print server's SNMP trap destination list. The command format is:
trap-dest: ip-address [community name] [port number]
The default community name is “public”; the default SNMP port number is “162”. The port number cannot be specified
without a community name.
If a “trap-community-name” command is followed by “trap-dest” commands, the trap community name will be assigned
to those entries unless a different community name is specified in each “trap-dest” command.
To delete the table, use “trap-dest: 0”.
If the list is empty, the print server does not send SNMP traps. The list may contain up to three entries. The default
SNMP Trap Destination List is empty. To receive SNMP traps, the systems listed on the SNMP trap destination list must
have a trap daemon to listen to those traps.
Other Settings
link-type:
■ Sets the print server's link speed (10, 100 Mbps) and communication mode (Full- or Half-Duplex). The available link-
speed selections are AUTO, 100FULL, 100HALF, 10FULL, 10HALF.
For AUTO (default), the print server uses auto-negotiation to configure itself with the highest link speed and
communication mode allowed. If auto-negotiation fails, either 100TX HALF or 10TX HALF is set depending on the
detected link speed of the hub/switch port.
Support
support-name: (or support-contact:)
■ Typically used to identify the name of a person to contact for support of this device.
support-number:
■ Typically used to specify a phone number or extension to call for support of this device.
22 Chapter 3 TCP/IP Configuration ENWW
Table 3-2 TFTP Configuration File Parameters (continued)
support-url:

tech-support-url:
■ A Web URL for technical support over the Internet or an intranet.
Using DHCP
Dynamic Host Configuration Protocol (DHCP, RFC 2131/2132) is one of several auto configuration
mechanisms that the HP Jetdirect print server uses. If you have a DHCP server on your network, the
HP Jetdirect print server automatically obtains its IP address from that server and registers its name
with any RFC 1001 and 1002-compliant dynamic name services as long as a WINS (Windows
Internet Naming Service) server IP address has been specified.
A TFTP (Trivial File Transfer Protocol) configuration file may also be used with DHCP to configure
extended parameters. For more information on TFTP parameters, see
NOTE DHCP services must be available on a network server. Refer to your system
documentation or online help to install or enable DHCP services.
Using BOOTP/TFTP.
NOTE If the Jetdirect print server and BOOTP/DHCP server are located on different
subnets, IP configuration may fail unless the routing device allows the transfer of DHCP
requests between subnets.
UNIX Systems
For more information on setting up DHCP on UNIX systems, see the bootpd man page.
On HP-UX systems, a sample DHCP configuration file (dhcptab) may be located in the /etc
directory.
Since older HP-UX systems may not provide Dynamic Domain Name Services (DDNS) for its DHCP
implementations, HP recommends that you set all print server lease durations to “infinite” for these
systems. This ensures that print server IP addresses remain static until dynamic domain name
services are provided.
Windows Systems
HP Jetdirect print servers support IP configuration from a supported Windows DHCP server. This
section describes how to set up a pool, or “scope,” of IP addresses that the Windows server can
assign or lease to any requester. When configured for BOOTP or DHCP operation and powered on,
the HP Jetdirect print server automatically sends a BOOTP or DHCP request for its IP configuration.
If properly set up, a Windows DHCP server will respond with the print server's IP configuration data.
NOTE This information is provided as an overview. For specific information or for additional
support, see the information supplied with your DHCP server software.
NOTE To avoid problems resulting from IP addresses that change, HP recommends that all
printers be assigned IP addresses with infinite leases or reserved IP addresses.

HP Jetdirect configuration page.)
d Under “Supported types”, select DHCP only, then click Add. (Note: Selecting Both or
BOOTP only will result in a configuration through BOOTP due to the sequence in which HP
Jetdirect print servers initiate configuration protocol requests.)
e Specify another reserved client, or click Close. The reserved clients added will be displayed
in the Reservations folder for this scope.
12 Close the DHCP manager utility.
NetWare Systems
NetWare 5.x servers provide DHCP configuration services for network clients, including the HP
Jetdirect print server. To set up DHCP services on a NetWare server, refer to Novell documentation
and support.
To Discontinue DHCP Configuration
CAUTION Changes to an IP address on your HP Jetdirect print server may require updates
to printer or system printing configurations for clients or servers.
If you do not want your HP Jetdirect print server configured through DHCP, you must re-configure
the print server to use a different configuration method.
1 If you use the printer control panel to set Manual or BOOTP configuration, then DHCP will not be
used.
2 You can use Telnet to set Manual (status indicates “User Specified”) or BOOTP configuration,
then DHCP will not be used.
3 You can manually modify the TCP/IP parameters through a supported Web browser using the
Jetdirect embedded Web server or HP Web Jetadmin.
If you change to BOOTP configuration, the DHCP-configured parameters are released and the TCP/
IP protocol is initialized.
If you change to Manual configuration, the DHCP-configured IP address is released and the userspecified IP parameters are used. Therefore, if you manually provide the IP address, you should
also manually set all of the configuration parameters, such as subnet mask, default gateway,
and idle timeout.
ENWW Using DHCP 25
NOTE If you choose to re-enable a DHCP configuration, the print server will acquire its
configuration information from a DHCP server. This means that when you choose DHCP and
complete your configuration session (using Telnet, for example), the TCP/IP protocol for the
print server is re-initialized and all current configuration information is deleted. The print server
then attempts to acquire new configuration information by sending DHCP requests on the
network to a DHCP server.
For DHCP configuration through Telnet, refer to Using Telnet in this chapter.
Using RARP
This section describes how to configure the print server using the Reverse Address Resolution
Protocol (RARP) on UNIX and Linux systems.
This setup procedure enables the RARP daemon running on your system to respond to a RARP
request from the HP Jetdirect print server and to supply the IP address to the print server.
1 Turn the printer off.
2 Log onto your UNIX or Linux system as a superuser.
3 Make sure the RARP daemon is running on your system by typing the following command at the
system prompt:
ps -ef | grep rarpd (UNIX)
ps ax | grep rarpd (BSD or Linux)
4 The system response should be similar to the following:
861 0.00.2 24 72 5 14:03 0:00 rarpd -a
860 0.00.5 36 140 5 14:03 0:00 rarpd -a
5 If the system does not display a process number for the RARP daemon, see the rarpd man page
for instructions on starting the RARP daemon.
6
Edit the /etc/hosts file to add your designated IP address and node name for the HP Jetdirect
print server. For example:
192.168.45.39 laserjet1
7
Edit the /etc/ethers file (the /etc/rarpd.conf file in HP-UX 10.20) to add the LAN
hardware address/station address (from the configuration page) and the node name for the HP
Jetdirect print server. For example:
00:01:E6:a8:b0:00 laserjet1
NOTE If your system uses Network Information Service (NIS), you need to incorporate
changes to the NIS host and ethers databases.
8 Turn the printer on.
9 To verify that the card is configured with the correct IP address, use the ping utility. At the
prompt, type:
26 Chapter 3 TCP/IP Configuration ENWW
ping <IP address>
where <IP address> is the assigned address from RARP.
10 If ping does not respond, see
Troubleshooting the HP Jetdirect Print Server.
Using the arp and ping Commands
You can configure an HP Jetdirect print server with an IP address using an ARP (Address Resolution
Protocol) command from a supported system. The protocol is not routable, that is, the workstation
from which the configuration is made must be located on the same network segment as the HP
Jetdirect print server.
Using the arp and ping commands with HP Jetdirect print servers requires the following:
■ Windows NT/2000/XP/Server 2003 or UNIX system configured for TCP/IP operation
■ A legacy default IP address 192.0.0.192 has been set on the print server
■ The LAN hardware (MAC) address of the HP Jetdirect print server (specified on an HP Jetdirect
configuration page)
NOTE On some systems, superuser rights may be required for the arp command.
After an IP address is assigned through arp and ping commands, use other tools (such as Telnet,
embedded Web server, or HP Web Jetadmin software) to configure other IP parameters.
To configure a Jetdirect print server, use the following commands:
arp -s <IP address> <LAN hardware address>
ping <IP address>
where <IP address> is the desired IP address to be assigned to the print server. The arp
command writes the entries to the arp cache on the workstation, and the ping command configures
the IP address on the print server.
Depending on the system, the LAN hardware address may require a specific format.
For example:
■ For Windows NT 4.0, 2000, XP, Server 2003
arp -s 192.168.45.39 00-01-E6-a2-31-98
ping 192.168.45.39
■ For UNIX
arp -s 192.168.45.39 00:01:E6:a2:31:98
ping 192.168.45.39
ENWW Using the arp and ping Commands 27
NOTE Once the IP address has been set on the print server, additional arp and ping
commands will be ignored. Once the IP address is configured, arp and ping cannot be used
unless the print server is reset to factory values (see
Server).
On UNIX systems, the arp -s command may vary between different systems.
Some BSD-based systems expect the IP address (or host name) in reverse order. Other
systems may require additional parameters. See your system documentation for specific
command formats.
Using Telnet
This section describes how to configure the print server (firmware version V.30.xx) using Telnet.
Although a Telnet connection may be protected by an administrator password, Telnet connections
are not secure. For networks with high security levels, Telnet connections can be disabled on the
print server using other tools (for example, TFTP, embedded Web server, or HP Web Jetadmin
software).
Creating a Telnet Connection
To use Telnet commands with the HP Jetdirect print server, a route must be available from your
workstation to the print server. If the print server and your computer must have a similar IP address,
that is, the network portion of their IP addresses match, chances are that a route will exist. For
information on IP address structure, see
Troubleshooting the HP Jetdirect Print
TCP/IP Overview.
If their IP addresses do not match, then you can either change your workstation's IP address to
match, or you can try an operating system command to create a route to the print server. (For
example, if the print server is configured with a legacy default IP address 192.0.0.192, a route will not
likely exist.)
On Windows systems, you can use the route command at a Windows command (DOS) prompt to
create a route to the print server.
For information on system command prompts, see your Windows online help. On Windows NT
systems, the command prompt utility is in the Programs folder (click Start, Programs, Command
Prompt). On Windows 2000/XP/Server 2003 systems, it is in the Accessories folder in the
Programs or All Programs folder.
To use the route command, you will also need the IP address of your workstation. To view it, you can
enter the appropriate command at the command prompt:
C:\> ipconfig (on Windows NT/2000/XP/Server 2003)
C:\> winipconfig (on Windows 98)
To create a route from the system command prompt, enter the following command:
route add <Jetdirect IP Address> <system IP Address>
where <Jetdirect IP address> is the IP address configured on the HP Jetdirect print server,
and <system IP address> is the IP address of the workstation's network card that is attached to
the same physical LAN as the print server.
28 Chapter 3 TCP/IP Configuration ENWW
For example, to create a route from your workstation with IP address 169.254.2.1 to a print server
with a default IP address of 192.0.0.192, try this command:
route add 192.0.0.192 169.254.2.1
CAUTION Using Telnet to manually set an IP address will override dynamic IP configuration
(such as BOOTP, DHCP, or RARP), resulting in a static configuration. In a static
configuration, the IP values are fixed and the operation of BOOTP, DHCP, RARP and other
dynamic configuration methods may no longer function.
Whenever you are manually changing an IP address, you should also re-configure the subnet
mask and default gateway at the same time.
A Typical Telnet Session
Initiating a typical Telnet session is illustrated below.
To set configuration parameters, you must set up a Telnet session from your system to the HP
Jetdirect print server.
1 Type the following at the system prompt:
telnet <IP address>
where <IP address> is the IP address listed on the Jetdirect configuration page. See
Jetdirect Configuration Page.
2 A connection to the HP Jetdirect print server will be displayed. If the server responds with
“connected to IP address”, press Enter twice to make sure that the Telnet connection is
initialized.
3 If prompted for a user name and password, enter the correct values.
ENWW Using Telnet 29
HP
By default, the Telnet interface does not require a user name or password. If an administrator
password has been set, you will be prompted for a user name and this password before you can
enter and save Telnet command settings.
4 By default, a Command Line interface is provided. To configure parameters using a Menu
interface, enter Menu. For more information, see
User Interface Options.
For a list of supported commands and parameters, see
Table 3-3 Telnet Commands and Parameters.
User Interface Options
The HP Jetdirect print server provides two interface options to enter Telnet commands: a Command
Line Interface (Default) and a Menu Interface.
Command Line Interface (Default)
Using the Telnet command line interface, you can set configuration parameters using the following
procedures:
NOTE During a Telnet session, enter ? to view available configuration parameters, the
correct command format, and a list of commands.
To list additional (or advanced) commands, enter the command advanced befored entering ?.
To display current configuration information, enter /.
1 At the Telnet prompt (>), type:
<parameter>: <value>
then press Enter, where <parameter> refers to the configuration parameter you are defining,
and <value> refers to the definitions you are assigning to that parameter. Each parameter entry
is followed by a carriage return.

See
2 Repeat the previous step to set any additional configuration parameters.
3
When you have finished typing the configuration parameters, type exit or quit (depending on
your system).
When prompted whether to save settings that you have changed, enter Y (default) for Yes, or N
for No.
If you enter save instead of exit or quit, you will not be prompted to save settings.

Using the Embedded Web Server
You can set IP parameters on HP Jetdirect print servers that support the embedded Web server. For
more information, refer to
Using the Embedded Web Server.
Using the Printer Control Panel
When supported by the printer, HP Jetdirect print servers provide a configuration menu that can be
accessed from the printer's control panel. Using this menu, you can enable, disable and set basic
network parameters. For a summary of the available menu items, see
Panel Menu.
NOTE For instructions on using the control panel for your printer, refer to your printer
documentation.
When accessing the HP Jetdirect menu from the printer's control panel, the TCP/IP network
configuration parameters that you can set include the following:
■
IP address of the print server
■
Subnet mask
■
Default gateway address
■
Syslog server address
The HP Jetdirect Control
■
Idle timeout period
■ IP host name
■ DHCP lease behavior (release or renew)
■ Primary and Secondary DNS servers
■ Link speed and communication mode
If you need to configure more TCP/IP parameters than allowed by control panel configuration, use an
alternate configuration tool (such as Telnet or the embedded Web server).
If the HP Jetdirect print server is configured with TCP/IP settings from the printer control panel, the
configuration is saved on the print server when powered off/on.
Moving to Another Network
When moving an HP Jetdirect print server that is configured with an IP address to a new network,
make sure that the IP address does not conflict with addresses on the new network. You may
change the IP address of the print server to one that can be used on the new network, or erase the
current IP address and configure another address on the new network. See
Jetdirect Print Server for instructions to reset the print server to factory default settings.
If the current BOOTP server is not reachable, you may need to locate a different BOOTP server and
configure the printer to this server.
Troubleshooting the HP
If the print server was configured using BOOTP, DHCP or RARP, edit the appropriate system files
with updated settings. If the IP address was manually set (for example, from the printer control panel
or Telnet), re-configure IP parameters as described in this chapter.

available from HP online support at the following URL:
http://www.hp.com/go/webjetadmin
HP Web Jetadmin version 7.8 (or greater) is recommended for operation with the HP Jetdirect
embedded Web server.
A link to HP Web Jetadmin will be displayed on the embedded Web server if HP Web Jetadmin has

For supported browsers with HP Web Jetadmin, visit http://www.hp.com/go/webjetadmin.
Viewing the Embedded Web Server
Before you can use the embedded Web server, the HP Jetdirect print server must be configured with
an IP address. For a description of an IP address and an overview of TCP/IP networking, see
Overview.
There are many ways to configure an IP address on the print server. For example, you can
automatically configure IP parameters over the network using BOOTP (Bootstrap Protocol) or DHCP
(Dynamic Host Configuration Protocol) each time the print server is turned on. Or, you can manually
configure IP parameters using the printer's control panel, Telnet, the “arp” and “ping” system
commands, HP Web Jetadmin or other management software. For more information on TCP/IP
configuration options, see
TCP/IP Configuration.
TCP/IP
When powered on, an HP Jetdirect print server that is unable to retrieve a valid IP address from the
network will automatically assign itself either a legacy default IP address 192.0.0.192 or a link-local
address in the range 169.254.1.0 to 169.254.254.255. The IP address configured on your print
server can be determined by inspecting the Jetdirect configuration page for the print server. See
IP Configuration for more information.
If the legacy default IP address 192.0.0.192 has been assigned, you must temporarily set up your
computer with the same IP network number or establish a route to the print server before you can
gain access to the embedded Web server.
After an IP address is established on the print server, perform the following steps:
1 Run a supported Web browser.
TCP/

print job that has already been formatted in PCL, PostScript, or HP-GL/2, and
sends it to the printer without modification. (Note that any user-defined prepend or
append string will be added to the job in the appropriate position.)
■ TEXT -- Carriage return added. The line printer daemon treats data in text queues
as unformatted or ASCII text, and adds a carriage return to each line before
sending it to the printer.
■ AUTO -- Automatic. The line printer daemon uses autosensing to determine
whether the print data should be sent as raw or text.
■ BINPS -- Binary PostScript. This instructs the PostScript interpreter that the printjob
is to be interpreted as Binary PostScript data.
Default Queue Name Name of the queue to be used if the queue specified for a print job is unknown. By

queues; this parameter names the string, and the Value parameter defines the content
of the string. Prepend and Append string names (specified in the table at the top of the
browser window) must be chosen from the names specified here. The string name can
be up to 32 characters long, and can consist of any displayable ASCII characters.
parameter defines its content. When a string name is specified for a prepend or append
string (in the table at the top of the browser window), the line printer daemon sends the
value of that string to the printer before or after the print data (as appropriate).
Character values can be anywhere in the extended ASCII range of 0 to 255 (hex 00 to
FF). You can specify a non-printing character using its hexadecimal value, by entering a
backslash followed by two hexadecimal characters. For example, to enter the escape
character (hex 1B), type in \1B. If your string includes the backslash character itself,
specify it as \5C. The maximum number of characters you can type into this field is 240.
The characters in the field are checked for hexadecimal values, converted if necessary,
and stored internally. The maximum number of characters stored internally in the string
is 80; any characters that exceed this are discarded.
To set up a user-defined print queue, you first define the strings, assign them as prepend or append
strings, and define the queue type. Once you have defined an LPD queue, you specify its use by
setting up an LPD printer that uses that queue. For instance, if you set up string “a” with a value of
“abc” and string “z” with a value of “xyz”, you can define print queue “az_queue” with a prepend
string of “a”, an append string of “z”, and a queue type of “raw”. Then, when you send a print job
consisting of <formatted_text> through queue az_queue, the job sent to the printer is
“abc<formatted_text>xyz”.
Instructions for setting up an LPD printer are different for different operating systems; refer to
Configuring for LPD Printing for details.
54 Chapter 4 Using the Embedded Web Server ENWW
Example. If you had an LPD printer and wanted to reset it at the start of each print job, you could set
up a user-defined print queue named “clear_printer” that issues a PCL reset command (Escape-E) at
the beginning of each job. You could set this up as follows:
First, set up the print queue:
■ Name a string: Type “reset_string” into the String Name field in row 1.
■ Define the string's value: Type “\1BE” (Escape-E) into the Value field in row 1. (Alternatively, you
could type “\1B\45”.)
■ Name the queue: Type “clear_printer” into the Queue Name field in row 5.
■ Set up the prepend string: Type “reset_string” into the Prepend String field in row 5.
■ Leave the Append String field in row 5 blank.
■ Set the queue type: Using the pull-down menu, set the Queue Type field in row 5 to “RAW”.
Then, set up the printer to use the queue, making sure to specify “clear_printer” when asked for a
queue name. (For details of setting up the printer, refer to
any print jobs sent to the printer -- either from the server or from a client computer that has set up
that printer -- will include a reset command at the beginning of the job.

Resetting to Factory Defaults
Parameters on the HP Jetdirect print server (for example, the IP address) can be reset to factory
default values using the following procedures:
The HP Jetdirect print server can be reset to factory defaults when a cold reset is performed on the
printer. A cold reset clears all data from the printer memory and sets all the defaults to factory settings.
CAUTION Be sure to print a Jetdirect configuration page before performing a cold reset.
Resetting the printer will clear all data from the printer memory and reset all printer settings,
including network configurations, to their factory default values. After a cold reset, users may
be affected due to changes in user-specified printer settings. Network systems may lose their
connection to the printer.
ENWW Resetting to Factory Defaults 65
NOTE The Restore Factory Settings menu item in the printer control panel menu will not

A TCP/IP Overview
This appendix is intended to provide information to help you gain a basic understanding of TCP/IP.
Similar to a common language that people use to communicate with each other, TCP/IP
(Transmission Control Protocol/Internet Protocol) is a suite of protocols designed to define the way
computers and other devices communicate with each other over a network.
TCP/IP is rapidly becoming the most used set of protocols. The main reason this is happening is the
fact that the Internet is based on TCP/IP. If you have a network that you wish to connect to the
internet, you must be using TCP/IP to communicate.
Internet Protocol (IP)
When information is sent across the network, the data is broken down into small packets. Each
packet is sent independently of one another. Each packet is encoded with IP information, such as the
IP address of the sender and receiver. IP packets can be routed over routers and gateways, devices
that connect a network with other networks.
IP communications is connectionless. When IP packets are sent, there is no guarantee that they
arrive at their destination in the proper sequence. That task can be performed by higher level
protocols and applications thereby allowing IP communications to be efficient.
Each node or device that will communicate directly onto the network requires an IP address,
including HP Jetdirect-connected devices.
Transmission Control Protocol (TCP)
TCP handles breaking the data into packets and recombining the packets on the receiving end by
providing a connection-oriented, reliable, and guaranteed delivery service to another node on the
network. When data packets are received at their destination, TCP calculates a checksum for each
packet to verify the data is not corrupt. If the data in the packet has been corrupted during
transmission, TCP discards the packet and requests that the packet be resent.
User Datagram Protocol (UDP)
UDP provides similar services to TCP. However, UDP does not acknowledge data receipt and
supports request/reply transactions with no added reliability or guarantee of delivery. UDP is used
when acknowledgment and reliability are not required, such as during a “discovery broadcast.”
ENWW Internet Protocol (IP) 85
IP Address
Every host (workstation or node) on an IP network requires a unique IP address for each network
interface. This address is a software address that is used to identify both the network and specific
hosts located on that network. Each IP address can be divided into two separate parts: the network
portion and the host portion. It is possible for a host to query a server for a dynamic IP address each
time the device boots-up (for example, using DHCP and BootP).
NOTE When assigning IP addresses, always consult the IP address administrator. Setting
the wrong address can disable other equipment operating on the network or interfere with
communications.
IP Address: (Network Portion)
Network addresses are managed by an organization in Norfolk, Virginia recognized as InterNIC.
InterNIC has been contracted by the National Science Foundation to manage the Internet addresses
and domains. Network addresses are distributed to organizations that are in turn responsible for
making sure all attached devices or hosts on the network are properly numbered. For more
information on the network portion of an IP address, see
Subnets later in this appendix.
IP Address: (Host Portion)
Host addresses numerically identify specific network interfaces on an IP network. Usually a host has
only one network interface; thus, only one IP address. Because no two devices can share the same
number at the same time, administrators typically maintain address tables to assure correct
assignment of addresses in the host network.
IP Address Structure and Class and
IP Address Structure and Class
An IP address is comprised of 32 bits of information and divided into 4 sections containing 1 byte
each section or 4 bytes total: xxx.xxx.xxx.xxx
For efficiency in routing, networks were broken down into three classes, so routing can begin simply
by identifying the leading byte of information in the IP address. The three IP addresses that InterNIC
assigns are class A, B, and C. The network class determines what each of the four IP address
sections identify as shown in
Table A-1 IP Address Class Format
Class First Address Byte
xxx.
A Network. Host. Host. Host
B Network. Network. Host. Host
C Network. Network. Network. Host
As illustrated in Table A-2 Network Class Characteristics, each network class differs by the leading
bit identifier, the address range, the number of each type available, and the maximum number of
hosts each class allows.

Configuring IP Parameters
TCP/IP configuration parameters (such as IP address, subnet mask, default gateway) can be
configured on the HP Jetdirect print server in a variety of ways. These values can be configured
manually (for example, through the printer control panel, Telnet, the embedded Web server, the arp
and ping commands, and HP management software), or they can be automatically downloaded
using DHCP or BOOTP each time the print server is turned on. For configuration methods, see
IP Configuration.
When powered on, a new HP Jetdirect print server that is unable to retrieve a valid IP address from
the network will automatically assign itself a default IP address. The default IP address will depend
on the type of network to which the print server is connected. On a small private network, a
technique called link-local addressing is used to assign a unique IP address in the range of
169.254.1.0 to 169.254.254.255, which should be valid. On a large or enterprise network, a
temporary address of 192.0.0.192 will be assigned until it is properly configured for your network.
The IP address configured on your print server may be determined by inspecting the Jetdirect
configuration page for the print server.

BOOTP is a bootstrap protocol used to download configuration parameters and host information from
a network server. BOOTP uses UDP for its transport. In order for devices to boot and load
configuration information into RAM, they must communicate through the bootstrap protocol BOOTP
as a client with their server.
To configure the device, the client broadcasts a boot request packet containing at least the hardware
address of the device (HP Jetdirect print server hardware address). The server answers with a boot
reply packet containing the information the device needs to configure.
Subnets
When an IP network address for a particular network class is assigned to an organization, no
provision is made for more than one network being present at that location. Local network
administrators use subnets to partition a network into several different subnetworks. Splitting a
ENWW Configuring IP Parameters 87
network into subnets can result in better performance and improved use of limited network address
space.
Subnet Mask
The subnet mask is a mechanism used to divide a single IP network into several different
subnetworks. For a given network class, a portion of an IP address that would normally be used to
identify a node is used, instead, to identify a subnetwork. A subnet mask is applied to each IP
address to specify the portion used for subnetworks, and the portion used to identify the node. For
example, see
Table A-3 Example: Subnet Mask 255.255.0.0 Applied to Class A Network
Class A Network Address 15 xxx xxx xxx
Subnet Mask 255 255 0 0

A IP network address “15” has been assigned to company ABC. To allow additional networks at
company ABC's site, the subnet mask of 255.255.0.0 is used. This subnet mask specifies that the
second byte of the IP address will be used to identify up to 254 subnets. Using this designation, each
device is uniquely identified on its own subnet, but company ABC can incorporate up to 254
subnetworks without violating their assigned address space.
Gateways
Gateways (routers) are used to connect networks together. Gateways are devices that act as
translators between systems that do not use the same communication protocols, data formatting,
structures, languages, or architectures. Gateways repackage the data packets and change the
syntax to match that of the destination system. When networks are divided into subnets, gateways
are required to connect one subnet to another.
Network Subnet Host Host

15 254 64 2
Default Gateway
The Default Gateway is the gateway or router that, if not specified, will be used to move packets
between networks. It is specified by an IP address.
If multiple gateways or routers exist, then the default gateway is typically the address of the first, or
nearest, gateway or router. If no gateways or routers exist, then the default gateway will typically
assume the IP address of the network node (such as the workstation or HP Jetdirect print server).

Syslog Server
A syslog server is a system on the network (typically a UNIX system) that can receive and log syslog
messages from other devices on the network. Syslog messages allow administrators to monitor
status or troubleshoot network devices.
A syslog server requires software that provides syslog capabilities running on the server. UNIX
systems provide a daemon, syslogd, that monitors User Datagram Protocol (UDP) port 514 for
incoming messages. The messages are processed depending on their priority and on how syslogd is
set up to operate.
You can configure the HP Jetdirect print server with the syslog server's IP address. When a syslog
server is configured, both the HP Jetdirect print server and attached device can send syslog
messages using UDP.
The syslog server may not receive all syslog events from the HP Jetdirect print server:
■ UDP does not guarantee delivery of messages.
■ The HP Jetdirect print server attempts to eliminate duplicate messages (to minimize
unnecessary network traffic).
■ The volume of messages sent by the HP Jetdirect print server is configurable.
Methods to configure HP Jetdirect syslog parameters include BOOTP, DHCP, Telnet, the embedded
Web server, and management software. For selected printers, a menu accessed through the printer
control panel provides limited syslog configuration. The syslog configuration command or parameter
entries may vary depending on the method used. For more information, see the applicable sections
in this guide.
Selected syslog parameters on the HP Jetdirect print server are listed in
Table A-4 HP Jetdirect
Syslog Parameters.

Jetdirect print server uses LPR as the source facility code, but local user values

B The HP Jetdirect Control Panel Menu
HP Jetdirect embedded print servers provide a configuration menu that can be accessed from the
printer's control panel. The keystrokes to access this menu from the printer control panel depend on
the printer. Refer to your printer User guide, or print a control panel menu map, for more information.
The printer's graphical control panel is used to access the Jetdirect print server menu items.
Graphical control panels typically display 18 characters on a line, and as many as four lines at a
time. In addition, scrolling may be supported to allow display of additional lines.
