introduction

hp wireless print server

overview

The print server is a printer accessory

that supports the IEEE 802.11b

standard for wireless LAN (WLAN)

communications. When the print server

is attached to a printer, appropriately

configured computers can send print

jobs to the printer over the WLAN.

When a computer sends a file to the

printer, a radio signal is transmitted.

When the print server receives the

incoming signal, either directly from the

computer (ad hoc/computer to computer

mode) or from an access point

(infrastructure/AirPort Network mode),

the printer prints the file.

With the wireless print server, users can

roam without losing printing capability

and network administrators have greater

flexibility in network design.

whom this guide is written

for

This guide is for network users and

administrators who have a working

knowledge of the following:

•wirelessLANtechnology

• print server technology

• the operating system(s) running on the

computer(s) being configured to use

the print server

terms and conventions

terms

This guide uses ad hoc mode and

infrastructure mode to refer to the two

operating modes in which the print

server can function in Windows.

Macintosh uses the terms computer to

computer and AirPort Network for the

two operating modes.

Terms you may find associated with ad

hoc mode are peer-to-peer or

independent basic service set (IBSS).

Terms associated with infrastructure

mode are networking, enterprise, or star

topology.

The HP Wireless Print Server wp110 is

referred to as the print server.

definitions

The Configuration Guide also uses the

following terms:

•access point — a bridge that links the

wireless LAN to the wired LAN.

•DHCP — dynamic host configuration

protocol. A protocol that provides

dynamic IP address allocation.

•passphrase — a string of characters

or words used to generate the WEP

key.

•SSID —service set identifier. A

wireless LAN naming convention that

provides access control by logically

segmenting the LAN; also known as

Electronic System Identifier (ESSID)

and WLAN Service Area ID.

•WEP — Wired Equivalent Privacy. A

security protocol for WLANs defined

in the IEEE 802.11b standard,

provides security by encrypting data

over radio waves.

•WEP key —a shared key algorithm for

encrypting data.

•WLAN — wireless local area network.

WLAN concepts: the

802.11b standard

The print server supports the IEEE

802.11b standard to provide standards-

based compatibility with a wide range

of products.

IEEE 802.11b standardizes wireless

communications on layers one and two

of the ISO OSI model (the physical layer

and data link layer).

An 802.11b WLAN:

• communicates using radio waves that

penetrate many indoor structures and

can reflect around obstacles.

Throughput depends on several

factors including the number of users,

microcell range, interference,

multipath propagation, standards

support, and hardware type.

• operates within the 2.4 GHz ISM

band

• divides the 2.4 GHz band into 14

channels using direct-sequence

spread spectrum (DSSS)

• uses Carrier Sense Multiple Access

with Collision Avoidance (CSMA/

CA) to avoid packet collisions

The Wireless Ethernet Compatibility

Alliance (WECA) tests 802.11b systems

for compliance and interoperability.

WECA certified products carry the Wi-Fi

(Wireless / Fidelity) logo. Hewlett-

Packard is a member of WECA.

operating modes

The print server can be configured for ad hoc/computer to computer or infrastructure/

AirPort Network operating mode.

print server management

The print server can be accessed and

monitored using:

• the embedded Web server (Windows

only)

• the wp110 utility (Macintosh only)

•telnet

• HP Web JetAdmin, HP's premiere

printer management software. Go to

www.hp.com/go/webjetadmin for

information on HP Web JetAdmin.

security: wired equivalent

privacy

Improve the security of your wireless

network in infrastructure mode by using

the Wired Equivalent Privacy (WEP)

features of the print server. WEP

supports data encryption and access

control. For WEP to work, the encryption

key on the print server must be set to the

same value as the access point.

Note Wireless transmission speed is

reduced when WEP is enabled due to the

time required for encryption and

decryption.

ad hoc/computer to computer mode infrastructure mode/AirPort network

Allows the devices to communicate directly

without being wired to a network. This is the

default operating mode for the print server.

Allows both wireless and wired computers to

send files to the printer through an access

point.

encryption

The server uses an optional 40- or 128-bit

encryption key. While the computer and

access point are associated, data

transmissions can be encrypted using this

key. Only users with the correct key can

decrypt the data.

When encryption is in use, the access

point issues an encrypted challenge

packet to any device attempting to

associate with it. The device must use its

key to encrypt the correct response in

order to authenticate its transmissions and

gain network access.

SSID

SSID is a naming convention that

provides basic access control to the

network. Each wireless network is

assigned an SSID. This information is

equired for any wireless computer to

associate with another computer or any

access point on the wireless network.

passphrase

A passphrase is a string of characters or

words that are used by a WEP algorithm

to generate the WEP key.

Note Implementation of WEP algorithms

may vary from one vendor to another.

signal range

The range in which devices can

communicate with the print server

depends upon the environment in which

the print server is installed. Typical

usage in an office is up to a maximum of

100 feet (30 meters).

Note Performance speed of the wireless

transmission reduces as the distance

between devices increases.

configuring the print server for Windows

This section describes how to configure the print server in Windows (if configuring multiple

print servers, only one print server can be configured at a time). Before you begin, verify

that:

• the computer uses Windows 98, NT 4.0, Me, or 2000.

• the print server is properly connected and a Print Server Configuration Page was

printed and saved for reference (see page 17 for printing instructions).

• the WLAN network interface card is properly installed and working correctly on the

computer.

• each computer using the print server has the HP Network or Corporate User driver

(also known as the Add Printer driver) to install the printer. Printer drivers are

available at www.hp.com/support/printers. You may also install the driver using the

printer's CD-ROM.

• the WLAN access point is working correctly (infrastructure mode only).

Follow these steps to configure the print server for Windows:

1. Using the computer’s wireless

configuration software, ensure the

computer is set to ad hoc mode.

2. Set the computer’s SSID to hp and

ensure that the WEP security feature is

disabled.

3. Verify the computer’s IP address. At

the DOS command prompt, type

ipconfig to display the IP address.

4. Establish a path from the computer to

the print server. The print server’s

default IP address is 192.0.0.192,

using 255.255.255.255 for the

Subnet and Gateway.

At the DOS command prompt, enter

route ADD, followed by the IP address

of the print server, then a space,

followed by the computer address.

For example, with a computer IP

address of 192.124.11.11, enter

route ADD 192.0.0.192

192.124.11.11. If DHCP is enabled on

the computer, allow two minutes for an

IP address to be assigned.

5. Enter 192.0.0.192 as the URL in a

browser to open the print server’s

Embedded Web Server.

Note Disable the web proxy if one is

being used on the computer.

6. In the Embedded Web Server, select

the Wireless Settings option from the

Configuration menu. Then:

a. Set the print server to the desired

mode (ad hoc or infrastructure).

b. Set the print server SSID to match

the SSID of the WLAN.

c. If using WEP security, enable the

WEP Request and enter the

appropriate WEP key as specified

by your network administrator.

7. Click Apply to apply changes. Reset

the print server by either selecting the

Reset option from the Configuration

menu or following the screen prompts.

8. Reconfigure the computer to match the

mode of the print server, if necessary.
