Introducing the HP Jetdirect Print

Introduction

HP Jetdirect print servers allow you to connect printers and other devices directly to a network. By attaching directly to a network, devices can be conveniently located near users. In addition, a network connection allows data transfers to or from the device at network speeds.

HP Jetdirect external print servers connect printers to the network by adapting the printer’s parallel port to a network port. Depending on the model, HP Jetdirect external print servers can connect up to three printers to a network.

Note Unless otherwise specified, the term print server in

HP Install Network Printer Wizard (Windows)

The HP install Network Printer Wizard is a utility for printer discovery, setup and installation on a TCP/IP network. Once your printers have a network connection, the wizard installs the printer on your systems or servers that will send print jobs directly to the printer. This is called “direct-mode”, or “peer-to-peer” printing.

If your system is a server, you can share the printer so that network clients can use the printer through the server, also known as “client-server” printing.

A version that runs from your system disk can be downloaded from HP online support at:

http://www.hp.com/go/inpw_sw

Requirements

● Microsoft Windows XP, Windows 2000, Server 2003 on TCP/IP

TCP/IP Configuration

Introduction

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. Depending on your printer and system, this can be done in the following ways:

Note When shipped from the factory, the HP Jetdirect

print server has no IP address. If the HP Jetdirect print server is not configured with a valid IP address within two minutes after power up, a factory default value of 192.0.0.192 will be automatically assigned. This address must be reconfigured with a valid address for use on your TCP/IP network. For more information on TCP/IP networks, see appendix

● By downloading the data from a network-based UNIX server

using BOOTP (Bootstrap Protocol) and TFTP (Trivial File Transfer Protocol) each time the print server is turned on.

Note The BOOTP daemon, bootpd, must be running on a

BOOTP server that is accessible by the print server.

● By using Dynamic Host Configuration Protocol (DHCP). This

protocol is supported in HP-UX, Solaris, Linux, Windows and Mac OS systems. (Refer to your network operating system manuals to verify that your operating system supports DHCP.)

ENWW 17

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 loaded in the /etc directory.

If your HP-UX system 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 available.

● By a network-based server using RARP (Reverse Address

Resolution Protocol) answering 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.

● By using the arp and ping commands from your system.

● By setting configuration parameters using Telnet. In order to set

configuration parameters, set up a Telnet connection from your system to the HP IP

address. The default IP address takes effect two minutes after

Jetdirect print server using the default

the printer is turned on (if none of the other configuration methods have been used). (Older products may take longer for the IP address to take effect.) The default IP address is

192.0.0.192. If Telnet is used, the print server saves the configuration even if the printer or print server is turned off.

● By browsing to the embedded Web server on the HP Jetdirect

print server and setting the configuration parameters.

18 TCP/IP Configuration ENWW

Using BOOTP/TFTP

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.

Note On supported Windows server systems, use the

Microsoft DHCP utilities to set up HP Jetdirect configuration via BOOTP. For more information, see “

Using DHCP”.

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).

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.

The factory-default state of the HP Jetdirect print server is to operate through BOOTP/TFTP.

ENWW TCP/IP Configuration 19

Systems That Use Network Information Service (NIS)

If your sys t e m uses NIS, y o u ma y n e ed to rebu i l d the N I S 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 “ parameters retrieved via TFTP are optional.

CAUTION Community names (passwords) for your printer are

not secure. If you specify a community name for your printer, select a name that is different from passwords used for other systems on your network.

Using DHCP

Dynamic Host Configuration Protocol (DHCP, RFC 2131/2132) is one of several auto configuration mechanisms that the HP 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.

Note DHCP services must be available on the server.

Refer to your system documentation or online help to install or enable DHCP services.

10. You have successfully set up the DHCP scope on this server. Click Finish to close the wizard.

11. Configure your printer with a reserved IP address within the DHCP scope:

a. In the DHCP tree, open the folder for your scope and select

Reservations.

b. Click the Action menu and select New Reservation.

c. Enter the appropriate information in each field, including

the reserved IP address for your printer. (Note: the MAC address for your HP Jetdirect-connected printer is available on the HP Jetdirect configuration page.)

d. Under “Supported types”, select DHCP only, then click

Add. (Note: Selecting Both or BOOTP only will result in a BOOTP configuration 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.

ENWW TCP/IP Configuration 29

Enabling or Disabling DHCP

If you do not want your HP Jetdirect print server configured via DHCP, you must disable DHCP configuration. There are three methods for enabling or disabling DHCP:

1. You can use Telnet to enable or disable DHCP operation on the HP Jetdirect print server. When you disable a DHCP configuration via Telnet, the print server automatically releases any names and IP addresses associated with the DHCP server and re-initializes the TCP/IP protocol for the print server. At this point, the print server is unconfigured and begins to send BOOTP and RARP requests to acquire new (non-DHCP) configuration information.

2. You can modify the TCP/IP parameters via HP Web Jetadmin.

If you manually provide an IP address when disabling DHCP via Telnet, the print server still releases its DHCP-provided IP address but does not send BOOTP and RARP configuration requests. Instead, it uses the configuration information you have provided.

Therefore, if you provide the IP address you should also manually set all of the configuration parameters, such as subnet mask, default gateway, and idle timeout.

Note If the DHCP configuration state is changed from

disabled to enabled, the print server assumes it should acquire its configuration information from a DHCP server. This means that when the Telnet session is completed, 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 via Telnet, refer to “Using Telnet” in this chapter.
