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.

2
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.

3
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.

4
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
r
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.

6
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.
