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 A.
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. 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.)
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 Jetdirect print server using the default IP address. The default IP address takes effect two minutes after 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.

Table 3.2 describes parameters that may be included in the TFTP configuration file.
Table 3.2 ews-config: TFTP Configuration File Parameters (1 of 3) Enables or disables the embedded web server on the HP Jetdirect print server. To enable, set to 1. To disable, set to 0. 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 90 seconds. Provides an entry into the host access list stored on the HP Jetdirect print server. Each entry specifies a host or network of hosts that are allowed to connect to the printer. The format is allow: netnum [mask] where netnum is a network number or host IP address, and mask is an address mask of bits applied to the network number and host address to verify access. Up to 10 access list entries are allowed. If there are no entries, all hosts are permitted access. For example: allow: 192.0.0.0 255.0.0.0 allows hosts on network 192. allow: 192.168.10.1 allows a single host. In this case, the default mask 255.255.255.255 is assumed and is not required. tcp-mss: Specifies the maximum segment size (MSS) that the HP Jetdirect print server will advertise for use when communicating with local subnets (MSS=1460 bytes or more) or remote subnets (MSS=536 bytes): 0 (default) All networks are assumed to be local (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. location: Identifies the physical location of the printer (SNMP sysLocation object). Only printable ASCII characters are allowed. The maximum length is 64 characters. The default location is undefined. (Example: 1st floor, south wall)

Using Telnet to Erase the Existing IP Address
To erase the IP address during a Telnet session: 1. Type cold-reset, then press Enter. 2. Type quit, then press Enter to exit Telnet. Note This procedure resets all TCP/IP parameters, but only affects the TCP/IP subsystem. After this has been done the print server should be power cycled. Parameters for other subsystems such as IPX/SPX (Novell NetWare) or AppleTalk are not affected.
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 Appendix B.

TCP/IP Configuration 39

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 after you are installed on the new network. Cold reset the print server (see Chapter 6, Troubleshooting the HP Jetdirect Print Server, for instructions). If the current BOOTP server is not reachable, you may need to locate a different BOOTP server and configure the printer to this server. 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, Telnet), reconfigure IP parameters as described in this chapter.

An IP address configured on the HP Jetdirect print server.

LPD Setup Overview

The following steps are necessary to configure the HP Jetdirect print server for LPD printing: 1. Setting up IP parameters. 2. Setting up print queues. 3. Printing a test file. The following sections provide detailed descriptions for each step.
Step 1. Setting Up IP Parameters
To set up IP parameters on the HP Jetdirect print server, refer to chapter 3. For more information on TCP/IP networks, refer to appendix A.
Step 2. Setting Up Print Queues
You must set up a print queue for each printer or printer personality (PCL or PostScript) you use on your system. Also, different queues are required for formatted and unformatted files. The queue names text and raw in the following examples (see rp tag) have special meanings.
Table 4.2 Supported Queue Names no processing carriage return added automatic
raw, raw1, raw2, raw3 text, text1, text2, text3 auto, auto1, auto2, auto3
Configuring for LPD Printing 43
The line printer daemon on the HP Jetdirect print server treats data in the text queue as unformatted text or ASCII, and adds a carriage return to each line before sending it to the printer. (Note that the actual observed behavior is that a PCL line termination command (value of 2) is issued at the beginning of the job.) The line printer daemon treats data in the raw queue as formatted files in PCL, PostScript, or HP-GL/2 languages and sends the data without change to the printer. Data in the auto queue will be automatically processed as text or raw, as appropriate. If the queue name is not one of the above, the HP Jetdirect print server assumes it to be raw1.
Step 3. Printing a Test File
Print a test file using the LPD commands. For instructions, see the information provided for your system.
44 Configuring for LPD Printing

LPD on UNIX Systems

Configuring Print Queues for BSD-based Systems Edit the /etc/printcap file to include the following entries: printer_name|short_printer_name:\ :lp=:\ :rm=node_name:\ :rp=remote_printer_name_argument:\ (this should be text, raw, or auto) :lf=/usr/spool/lpd/error_log_filename:\ :sd=/usr/spool/lpd/printer_name: where printer_name identifies the printer to the user, node_name identifies the printer on the network, and remote_printer_name_argument is the print queue designation. For more information on printcap see the printcap man page. Example 1 (suggested name for an ASCII or text printer): lj1_text|text1:\ :lp=:\ :rm=laserjet1:\ :rp=text:\ :lf=/usr/spool/lpd/lj1_text.log:\ :sd=/usr/spool/lpd/lj1_text: Example 2 (suggested name for PostScript, PCL, or HP-GL/2 printers): lj1_raw|raw1:\ :lp=:\ :rm=laserjet1:\ :rp=raw:\ :lf=/usr/spool/lpd/lj1_raw.log:\ :sd=/usr/spool/lpd/lj1_raw:

Verifying the Configuration
Print a file from any application. If the file prints correctly, the configuration was successful. If the print job is not successful, try printing directly from DOS using the following syntax: lpr -S<ipaddress> -P<queuename> filename where ipaddress is the IP address of the print server, queuename is the name raw or text and filename is the file you wish to print.If the file prints correctly, the configuration was successful. If the file does not print, or prints incorrectly, see the chapter Troubleshooting the HP Jetdirect Print Server.
Printing from Windows Clients
If the LPD printer on the Windows server is shared, Windows clients can connect to the printer on the server using the Windows Add Printer utility in the Printers folder.
52 Configuring for LPD Printing
FTP Printing Introduction
FTP (File Transfer Protocol) is a basic TCP/IP connectivity utility to transfer data between systems. FTP printing is a way to use FTP to send print files from a client system to an HP Jetdirect-connected printer. In an FTP printing session, the client connects and sends a print file to the HP Jetdirect FTP server which in turn passes the print file to the printer. The HP Jetdirect FTP server can be enabled or disabled through a configuration utility, such as Telnet.
FTP printing requires the following:
HP Jetdirect print servers with firmware version x.08.55 or later. TCP/IP client systems with FTP that complies with RFC 959. For the most recent list of tested systems, visit the HP online support at www.hp.com/support/net_printing.

Print Files

The HP Jetdirect FTP server transfers print files to the printer but does not interpret them. For proper printing, print files must be in a language recognized by the printer (such as PostScript, PCL, or unformatted text). For formatted print jobs, you must first print to a file from your application using the driver for the selected printer, then transfer the print file to the printer through an FTP session. For formatted print files, use binary (image) type transfers.

Using FTP Printing

FTP Connections
Similar to standard FTP file transfers, FTP printing uses two TCP connections: a control connection and a data connection. Once an FTP session is opened, it remains active until either the client closes the connection or the data and control connections are idle for 900 seconds (15 minutes). (This setting cannot be configured.) Control Connection Using standard FTP, a control connection is opened by the client to the FTP server on the HP Jetdirect print server. FTP control connections are used to exchange commands between the client and the FTP server. The HP Jetdirect print server supports up to three control connections (or FTP sessions) simultaneously. If the number of allowed connections is exceeded, a message indicating that service is not available will be displayed. FTP control connections use TCP port 21. Data Connection A second connection, a data connection, is created each time a file is transferred between the client and the FTP server. The client controls the creation of a data connection by issuing the commands that require a data connection (such as FTP ls, dir or put commands).

TCP/IP Overview 89

Subnets
When an IP address 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 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 networks. To subnet the IP address, the administrator must take part of the host area of the address and assign it for subnet numbers. The subnet mask masks out that specific portion of the host IP address along with the entire network section of the address with ones and leaves this portion as zeros, available to host addressing.
Table A.3 Bytes (Sections) Class A Network Subnet Mask Example IP Address 15 xxx xxx xxx Subnet Masks Network Subnet Host Host

255 15

255 254
In the table above, Subnet Masks, the Class A network 15 has been assigned to Hewlett-Packard. To allow additional networks at the HP site, the subnet mask of 255.255.0.0 is used. This address designates the second byte of the IP address as the subnet address. Using this designation, each device is uniquely identified on its own subnet, but HP can incorporate up to 254 subnetworks without violating their assigned address space.

90 TCP/IP Overview

Gateways
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.

Default Gateway

The Default Gateway is the address of the gateway or router that you use to move packets between subnets. If multiple gateways or routers exist, then the default gateway is the address of the first gateway or router that you use to move packets between subnets.

An external print server interfaces with an HP or non-HP printer via its parallel or USB port and requires an external power supply.

Internal print servers

Internal print servers plug into a slot on a printer or MFP and do not require an external power supply or interface cable. HP offers two types of internal print servers: EIO and LIO. With higher throughput speeds, EIO print servers are designed primarily for enterprise customers, while LIO print servers are designed for small and medium businesses. Because EIO and LIO print servers utilize different I/O (input/output) technologies, they are not interchangeable.

Embedded print servers

HP Jetdirect Fast Ethernet print server hardware components are now included on the formatter boards of many HP printers, MFPs, and digital senders. This efficient design allows the embedded print server to share the host devices CPU and memory. Unlike EIO print servers, embedded print servers have fewer components and do not require an EIO interface between the formatter board and the print server. Embedded print servers were developed to allow customers to share their peripherals on a network with a robust set of standard features. In addition, these peripherals feature EIO slots or a USB port for advanced or additional networking solutions, such as Gigabit Ethernet or 802.11b/g wireless. HP peripherals with full-featured embedded networking deliver outstanding performance and reinforce HPs leadership position with fast throughput speeds.
