A local area network (or
LAN) provides
connections that tie the
computers together and
allow them to
communicate. (The most
common type of local
area network may also be
referred to as an Ethernet
LAN or an Ethernet.)
Local area networks can
be either wired (as shown
here) or wireless. We will
look at the different types
in the next few pages.
As the name implies, a
wired LAN connects
computers (and other
network devices)
physically, using wires. A
typical LAN uses twistedpair wiring (similar to
telephone wiring) to
connect each computer to
a central hub. The hub
transmits network
communications between
computers.
Wired LANs offer highspeed communication, as
well as reasonable
security and reliability. In
general, however, they are
not as flexible as wireless
LANs.
Most wired LANs
conform to the IEEE
802.3 standard. The most
common wiring schemes
use twisted-pair wiring or
thin coaxial wiring.

Wiring: twistedpair
The most common wiring
used for LANs is twistedpair wiring, similar to the
wiring used for
telephones. This wiring
connects the computers or
other network devices to a
central hub. The use of
telephone-type wiring
makes it easy for the
persons who administer
your telephone wiring to
administer the network
wiring as well.
RJ-45 connectors are used
to connect the twistedpair wiring to the
computer and to the hub.
The wire for a network
can be graded in a number
of categories; Category 5
wiring is the most popular
grade. Category 5 wiring
has superior electrical
characteristics, and we
strongly recommend it for
all twisted-pair
networking applications.
The wire grade is usually
marked on the cable
jacket.

twisted-pair LAN

Network Basics
commonly operates at a
data rate of either 10
Mbps (megabits per
second) or 100 Mbps.
Category 5 wiring is
required for 100-Mbps
operation. A 10-Mbps
LAN can run on either
Category 3 or Category 5
wiring (though we
strongly recommend
Category 5). At either data
rate, cables may extend up
to 100 meters (328 feet)
from the hub to the
computer.
A twisted-pair network
running at 10 Mbps is
called a type 10Base-T
network. A twisted-pair
network running at 100
Mbps is called a type
100Base-T network.

Wiring: thin
coax
An alternative to twistedpair wiring is thin coaxial
cabling, often called thin
coax. This cabling is
known as RG-58A or RG58U cable, and has an
impedance of 50 ohms.
(It looks similar to the 75ohm thin coaxial cable
used in television
installations, but the
television cable will not
work in a network.)
The connectors used with
thin coax are BNC
connectors. The cable is a
continuous cable, up to
185 meters (606 feet)
long, made up of shorter
segments with BNC
connectors at each end. It
connects to computers
and other devices along
its length using BNC "T"
connectors, and there is a
50-ohm terminator at
each end of the cable.
This cabling scheme does
not use a hub.

Computer
connections
For twisted-pair
LANs: A desktop
computer connects to a
twisted-pair LAN through
a network interface card
(NIC) that resides in a
slot in the computer, or
through a similar
interface built in to the
computer itself. The RJ45 plug of the network
cable plugs into an RJ-45
jack on the card or in the
computer. A portable
computer may have a
built-in connection using
an RJ-45 jack, or it may
use a PC card that inserts
into a PC card slot in the
computer. (Some PC
cards take up two slots
and have room for an RJ45 jack that is integral
with the card; others take
up only a single slot but
require a short cable that
provides the RJ-45 jack.)

LANs: A desktop
computer typically
connects to a thin coaxial
LAN through a network
interface card (NIC) ;

are uncommon. Portable
computers connecting to
thin coaxial LANs use a
PC card with a short cable
that provides a BNC
connection. In all cases,
the LAN cable connects to
the computer through a
BNC "T" connector.
Hidden network
cables and
equipment: In many
network installations, the
hubs are kept in
equipment closets and the
cables are hidden in the
walls. In these
installations, wall outlets
with RJ-45 jacks are the
only visible components
of the network wiring. For
such a network, you use a
short length of network
cable to connect from the
computer to the wall jack.

Wireless LANs
In a wireless LAN,
information travels
through the air in radiofrequency signals instead
of through wires. This
makes wireless LANs very
flexible, and setup and
reconfiguration are very
easy. Communication
speeds on wireless LANs,
however, tend to be
slower than on wired
LANs, and it generally
takes more work to make
a wireless LAN as secure
as a wired LAN.
Most wireless LANs
conform to one of the
subsets of the IEEE
802.11 standard; the most
common subset is
currently 802.11b. Data
rates for 802.11b LANs
can be as high as 11 Mbps
(megabits per second).
Typically a wireless device
in an 802.11b LAN can
transmit signals across a
distance of about 30
meters (100 feet) in a
semi-open office (no
walls) and still maintain a
data rate of 11 Mbps. It is
possible to extend the
range to about 100 meters
(300 feet), but at such a

distance the data rate
drops off to 1 Mbps.
802.11b wireless LANs
operate in the 2.4 GHz
frequency band. There are
several channels
(frequencies) that
wireless LANs can use in
this range. Government
regulations prescribe
which channels may be
used in various parts of
the world.
There are two basic
wireless networking
topologies -infrastructure mode and
ad hoc mode; these are
described in the detail

Infrastructure
mode
Terminology:
Infrastructure mode is
referred to as a "basic
service set" (BSS). It's
topology is sometimes
called a "star topology",
and it may also be called
"enterprise mode"
because it is the preferred
topology for large
networks. On a network
of Apple Macintosh
computers, it may be
called an "Airport
network".
Topology: In
infrastructure mode, all
signals travel through an
access point. Like the hub
in a wired LAN, the access
point re-sends the
incoming signals out to
the computers and other
devices on the network.
(The access point
performs additional
functions when a wireless
LAN is connected to a
wired LAN.)
Infrastructure mode is
suitable for wireless LANs
of all sizes.

In infrastructure mode
the access point sets the
channel for all device that
communicate through it.
A wireless LAN can have
multiple access points.
This can expand the
capacity of the network
and extend its range,
allowing users to roam
with their portable
computers and still stay
connected to the network.

Ad hoc mode
Terminology:
Infrastructure mode is
referred to as an
"independent basic service
set" (IBSS). It is
sometimes called "peer-topeer mode". On a network
of Apple Macintosh
computers, it may be
called "computer-tocomputer mode".
Topology: In ad hoc mode
the wireless devices on a
network communicate
directly with each other,
and access points are not
used. Ad hoc mode is used
for very small networks.
Performance in an ad hoc
network degrades as you
add more devices to the
network; typically, ad hoc
networks connect no more
than six devices.
In ad hoc mode you can
select the channel. Make
sure that all devices on the
network are set to the
same channel.
Not all wireless
connections are network
connections. Though the
distinctions may often be
somewhat blurry, some
wireless technologies -such as the Bluetooth
technology that is
becoming popular in
mobile phones and
handheld computers -are more about
connecting a computing
device to a peripheral,
rather than connecting
computers and other
devices in a network.
For instance, when a
handheld computer
connects with a walk-up
wireless printer, or when
a mobile phone connects
with a vending machine,
the interactions between
them are typical of a
standalone computer
talking to a peripheral
device. In essence, the
wireless connection
replaces the cable in a
standard peripheral
connection. Compared to
network connections,

Computer
connections
Connections at the
computer for wireless
networking connections
are simpler than wired
ones just because there
are no wires to connect.
Wireless connections are
most common in portable
computers. Increasingly,
notebook computers
come with built-in
wireless networking. For
notebook computers that
don't have built-in
networking, you can plug
a wireless networking
card into the computer's
PC card (PCMCIA) slot.
(Wireless networking is
based on radio
technology, and in many
add-on cards the antenna
protrudes slightly from
the PC card slot.)
Desktop PCs can have
wireless networking, too.
A typical arrangement is
for an adapter in a
desktop PC to contain a
PC card slot, into which
you plug the same kind of

Mixed LANs
Mixed LANs combine
wired and wireless LANs,
taking advantage of the
strong points of each. For
example, a mixed LAN
can provide the flexible
connections of wireless
with the high overall
throughput of a wired
LAN. Such an
arrangement makes it
particularly easy for
mobile workers to
connect their notebook
computers to the
network.
You create a mixed LAN
by plugging the network
cable from a wired LAN
into a port on a wireless
access point. In addition
to acting as a hub for the
wireless portion of the
network, the access point
acts as a bridge to the
wired portion. In a typical
case, when a computer
with a wireless LAN card
comes within range of the
access point, it connects
through the access point
to the LAN (both the
wired and wireless
portions) and to all the
computers and other
resources on the LAN.

L is for Local
The "local" in "local area
network" means that the
network is in a single
location. A LAN can be
small enough to serve a
home office or a small
business, or it can be
large enough to serve a
school, a hospital, or a
substantial business or
public office. It can cover
several buildings, as long
as they can all be
connected into a single
network. Several types of
LAN equipment are
available to expand a LAN
beyond the workgroupsized unit typically served
by a single hub.
Note that the definition of
a local area network does
not include broader
networks such as the
Internet or a corporate
network with locations in
many cities or countries.
These broader networks
are often called WANs, or
wide area networks. It is
possible for a LAN to
connect to such a network
through a gateway -- a
device that connects
different types of
networks. The gateway

Addresses
Each device on the
network has a unique
address. This allows you
to communicate with a
specific computer (or
other device, such as a
printer). That way, your email doesn't go to
everybody, and your print
job doesn't get printed
simultaneously on all
printers on the network.
There are several
addressing schemes for
networks. Of these, the
most popular is that of the
Internet Protocol (IP). In
addition to being used on
the Internet, IP
addressing can also be
used for standalone
networks that don't
connect to the Internet.
The network addresses
shown in the illustration
are sample IP addresses.
Other network addressing
schemes you may
encounter include IPX
(used with Novell
NetWare networks), DLC,
and AppleTalk. In this
tutorial, we limit our
discussion of network
addressing to IP

addressing, as it is the
most popular.
The number of possible IP
addresses is huge. So is
the number of Internet
users, and the possibility
of conflicts is a real one. If
you use IP addresses on
your LAN and that LAN
connects to the Internet,
you must be careful to use
addresses that have come
from a reliable source,
such as your Internet
service provider (ISP).

Wireless
security
Wireless networks are
inherently less secure than
wired ones. In a wired
environment an intruder
needs to gain physical
access to your network
wiring to break into your
network; in a wireless
environment, he just needs
to be in range of the radio
waves that carry the
network traffic. Since these
waves penetrate building
walls and easily carry for
tens of meters, an intruder
sitting in a car in your
parking lot could monitor
the traffic on the wireless
LAN in your building.
To frustrate intruders, a
number of standards have
been developed to make
security for a wireless
network more-or-less
equivalent to that of wired
networks. These standards
work in three areas:
Network name (SSID):
A network name, or service
set identifier (SSID) is an
alphanumeric character
string that provides basic
access control on a wireless
network. To transmit onto

the network, the network
name of a computer or
other device must match
the name configured into
the access point.
Authentication:
Authentication verifies the
identity of a user or device
before the user or device is
allowed to transmit onto
the network. There are
several different schemes of
authentication that you
might encounter when
installing an HP Jetdirect
print server:
●Open system: No
authentication.
●Shared key: Each
device uses the same
shared key (a shared
password value) for
network access.
●Server-based
authentication: A
server on the
network
authenticates each
client that requests a
connection to the
network. There are
several protocols
available, all based
on the Extensible
Authentication
Protocol (EAP).
Briefly described,
they are:
❍LEAP
(Lightweight
Extensible

Protocol) -- a
proprietary
protocol from
Cisco Systems
that uses
passwords for
mutual

certificates for

unintelligible to an intruder
who is monitoring it. WEP
(wired equivalency privacy)
is an IEEE 802.11
encryption scheme that
provides basic access
control and data privacy on
your wireless network.
Under WEP, you supply
encryption keys that are
used to encrypt the data
stream.
In addition, some of the
authentication protocols,
such as LEAP and EAPTLS, can manage
encryption keys for the
network administrator.

sharing printers among
several users, you reduce
the number of printers

Why use a print
server?
A print server provides
your printer with
connection to the
network. You could get
the same connection
using a computer -- your
network server -- but it
would cost more and be
more complex. Using a
print server saves you
money and frees up your
network server for other
tasks, such as file storage.
You might want to use a
network server for
management of print
jobs, a function that may
be useful for larger
networks. In such an
application you will still
probably want to use a
print server, because its
small size gives you
location flexibility. Using
a print server, you can
easily place your printers
near your users, while
keeping the network
server out of the way in a
central computer area.

Hardware
connections
Print servers can be
internal or external
devices. Which one you
choose depends on your
printer.
Internal print servers
-- These are special-
purpose cards or modules

input/output slot in the
back of some printers.
The slot provides the data

for the print server, and
the network cable plugs

and connects to the
printer's USB or parallel
port using a standard

network connector on the
print server, and a power
cord connects to a wall
outlet to provide the print
server's power. (We

cord in the illustration,
just to keep the drawing
simpler.)
External print servers
come in several different
configurations to match

NETWORK PRINTING
Peer-to-peer
topology
There are two standard
layouts for network
printing using a print
server. The first is the peerto-peer topology, in which
a computer sends print
jobs directly to the printer.
In peer-to-peer printing,
each computer manages
the print jobs that it
generates. It checks to see
whether the printer is
ready to accept the print
job, and sends the job if
the printer is free. If the
printer is not free, the
computer stores the job
and keeps checking the
printer until it is ready to
accept the job. If several
computers send jobs to a
printer at the same time,
printing for some of the
computers may slow down
as they spend time
checking the printer and
waiting for it to be
available.
Peer-to-peer printing
works well on networks
with few users. It is
appropriate for small and

have heavy printing
requirements.
(Note: To clarify the use
of similar terminology,
please note the distinction
between wireless peer-topeer mode (usually known
as "ad hoc mode") and HP
Jetdirect peer-to-peer
printing. Wireless peer-topeer mode refers to a
topology where wireless
devices communicate
directly without going
through an access point,
while HP Jetdirect peer-topeer printing refers to a
computer's direct print
path to a printer that does
not go through a network
server. HP Jetdirect peerto-peer printing can be
used on both
infrastructure and ad hoc
(peer-to-peer) wireless
topologies.)

NETWORK PRINTING
Client/server
topology
The second standard
layout for network
printing is the
client/server topology. In
this topology, a computer
sends its print jobs to a
network server, and the
server sends the print jobs
to the printer.
In client/server printing,
the network server
manages the print jobs
from several computers
(the clients). As soon as a
client computer has sent a
print job to the server, it is
finished with that print
job. The server keeps
track of all print jobs from
there on -- figuring out
the print order for the
various jobs that have
been submitted to it,
checking the printer's
availability, and sending
the next job to the printer
when it is free.
Client/server printing
works well on networks
with heavy printing
traffic. It is typically used
in large offices that have
extensive networking

facilities.
Choosing a topology --
If you don't know whether
to use a peer-to-peer or a
client/server topology,
you may want to start
with peer-to-peer
printing. It generally takes
a substantial amount of
printing traffic, or large
print jobs, to slow down
printing significantly. If
your print jobs start to
take noticeably longer to
complete, you may want
to try using multiple
printers, dividing your
network into
subnetworks, or switching
your office to client/server
printing (in that order).

NETWORK PRINTING
Printer drivers
The printer driver is the
last major component to
consider in network
printing. This driver is
system software that
converts a document in
your computer to a form
that makes sense for the
printer.
When you print from an
application on your
computer, it is the printer
driver that converts the
layout on your screen to
the ones and zeros that
the printer takes as input.
When the printer receives
this information, it
converts the ones and
zeros into a correctly
printed page.
The installer program for
network printing needs to
have the printer driver to
complete the installation.
It usually turns out that
the trickiest thing about
the installation is
knowing where to find the
driver. You may be able to
find the driver on the CD
that came with your
printer, on the Web, or on
your operating system
CD. If you previously had
file:///C|/Bottlecap_Structure_26--TestMerge/DOCS/EN/NETBASIC/FNP0060.HTM (1 of 2) [5/20/2003 3:45:15 PM]
Network Basics
the same printer
connected directly to your
computer, the right driver
may already be on your
system. (We will provide
more information on
finding and using printer
drivers in the next
section, "Installing a
Network Printer".)
file:///C|/Bottlecap_Structure_26--TestMerge/DOCS/EN/NETBASIC/FNP0060.HTM (2 of 2) [5/20/2003 3:45:15 PM]
The first stage of
installing a network
printer is setting up the
hardware. There are two
steps to this: setting up
the printer hardware and
connecting the print
server.
Set up the printer
hardware -- Remove
any shipping materials.
Install the paper trays
and ink or toner
cartridges (as
appropriate). Add paper.
Plug in the power cord
and switch on the power.
Print a test page. Do not
connect the printer to
your computer. (For
detailed instructions,
check your printer
manual or setup poster.)
Connect the print
server -- There are a
couple of different cases
to consider:
●If you use an
external print
server: Switch off
the printer's power.
file:///C|/Bottlecap_Structure_26--TestMerge/DOCS/EN/NETBASIC/FIP0010.HTM (1 of 4) [5/20/2003 3:45:29 PM]
Network Basics
Connect the printer
cable (USB or
parallel, as
appropriate)
between the printer
and the print
server. Connect the
network cable to
the print server.
Switch on the
printer's power.
Plug in the print
server's power
cord. Push the Test
button on the print
server to print a
configuration page
on the printer; this
tests the
connection
between the print
server and the
printer. (For
detailed
instructions, check
your print server
manual or setup
poster.)
Note: For a
wireless print
server the
connection
sequence is the
same, except that
there is no network
cable to connect.
●If you use an
internal print
server: Note that
many printers
come with the print
server module
file:///C|/Bottlecap_Structure_26--TestMerge/DOCS/EN/NETBASIC/FIP0010.HTM (2 of 4) [5/20/2003 3:45:29 PM]
Network Basics
already installed in
the printer. If your
print server
module is not
already installed:
Unplug the
printer's power
cord. Plug the print
server into its slot
in the printer.
Connect the
network cable to
the network
connector on the
print server. Plug
in the printer's
power cord. (For
detailed
instructions, check
your print server
manual or setup
poster.)
Note: For a
wireless print
server the
connection
sequence is the
same, except that
there is no network
cable to connect.
Note: If your network
wiring is hidden -- In
many network
installations, the network
components (hubs,
switches, &c) are stored
in a wiring closet and the
network wiring is hidden
in the walls. The only sign
of a network that you see
in such an installation is a
file:///C|/Bottlecap_Structure_26--TestMerge/DOCS/EN/NETBASIC/FIP0010.HTM (3 of 4) [5/20/2003 3:45:29 PM]
Network Basics
wall outlet that has one or
two network connectors.
In this case, make your
network connection by
connecting a network
cable between the print
server and the wall outlet.
(If you have any questions
about such an
installation, check with
your network
administrator.)
Note that the illustration
shows only the data
connections (network
cables and printer cable);
we have omitted power
cords from the
illustration to keep the
drawings simple.

INSTALLING A NETWORK PRINTER
Running the Install Network
Printer Wizard ("the installer")
But first, are you installing a wireless
print server?
If you are installing a wireless print server, you will
need to run the HP Jetdirect Wireless Setup Wizard
before running the HP Install Network Printer
Wizard. Running the Wireless Setup Wizard is an
option that appears when you insert the HP Jetdirect
CD into your Windows computer.
The Wireless Setup Wizard guides you through:
●setting your computer to connect to the print
server in wireless ad hoc (peer-to-peer) mode
●discovering your wireless printer on the
network
●setting a few wireless parameters
(communication mode, authentication, and
encryption) on the print server
Then you set your computer back to its normal
connection to your network, and continue with
installing the printer on your computer, using the
Install Network Printer Wizard.
The Install Network Printer Wizard
The next (and last) stage of installing a network
printer is using the network printing software to
install the printer on your computer.
●If you're setting up peer-to-peer
printing, you need to run the software and
install the network printer on each computer
that will print to the target printer.
●If you're setting up client/server
printing, you need to run the software and
install the network printer on the network
server and set it up for printer sharing. Then
each client computer must install the printer
driver and connect to the shared printer on the
network server. An easy way to do this is to use
the Microsoft Windows Point and Print
function. (See your operating system
documentation for details on Point and Print.)
file:///C|/Bottlecap_Structure_26--TestMerge/DOCS/EN/NETBASIC/FIP0020.HTM (1 of 4) [5/20/2003 3:45:36 PM]
Network Basics
The installer program performs several major
functions:
● detects available printers on the network
● helps set up an address for the printer you
choose
● installs the printer driver
● optionally sets up printer sharing (only
available if running on a Windows NT/2000
network server)
Operation
Note: The next few paragraphs describe the operation
of the installer software that resides on the HP Jetdirect CD. If you are using the network printer
installer that resides on the printer's CD, the
operation may be slightly different from what we
describe here. In particular, some printer CDs do not
offer you the option of "Autoconfigure network
settings for me". In such a case, the installation will
proceed as though you chose the "Let me configure
my own network settings" option described below. (If
you are trying to decide whether to use the Jetdirect
CD or the printer CD, the discussion of
Which CD do I
use? may be helpful.)
To run the installer program, insert the CD into your
computer's CD-ROM drive. On most systems the CD
browser application will start automatically. If it
doesn't start automatically on your system, doubleclick on SETUP.EXE in the root directory of the CD to
start it. Once the browser has initialized, it will give
you a choice of actions -- choose Install by clicking on
the top button.
When the installer starts, it lets you choose how it
operates:
●Auto-configure network settings for me.
This is the easy option -- the installer
automatically assigns network settings, such as
IP addresses. This is probably the right option
to choose, unless you are a network
administrator and need to assign specific
network settings.
●Let me configure my own network
settings. This is the option for advanced
users. It gives you control over the IP or
NetWare parameters and other network
settings that are assigned to the network
printer. If you are a network administrator,
this may be the right choice for you.
file:///C|/Bottlecap_Structure_26--TestMerge/DOCS/EN/NETBASIC/FIP0020.HTM (2 of 4) [5/20/2003 3:45:36 PM]
Network Basics
Once you have made this choice, the installer
proceeds with its tasks, asking you for the
information it needs at each point. If you chose "Autoconfigure . . ." it will ask only a few questions; if you
chose "Let me configure . . ." it will ask some detailed
questions about the setup of network addressing.
Printer drivers
At some point late in the installation, the installer
needs to have the printer driver to complete the
installation. So at that point the installer may ask you
where to find the driver. Knowing where to find the
driver is usually the trickiest part of the installation.
Technically speaking, what you need is a driver that
installs using a .INF information file (rather than
installing by running a .EXE file) There are several
alternatives for finding this driver and its .INF file:
●In many cases this is the same driver that is
used for a direct (non-networked) printer
connection, and you can probably find the
driver on the CD that came with the printer.
(In fact, some printers come with the network
installer program on the printer CD. If your
printer is one of these, the simplest way to
install your network printer is to run the
installer from the printer CD instead of from
the HP Jetdirect CD, since the installer knows
where to find the driver on the printer CD. For
a list of these printers, click on this button:
.)
●If you want to make sure of having the latest
driver for your printer, you can download it
from the Web. If your printer is an HP printer
and you are running the installer in the
"Autoconfigure network settings for me" mode,
you can select the option to download a driver
automatically from the Internet. The installer
will search the HP support site for a driver for
your printer and, if it finds one, will
automatically download it and install it for you.
If you don't select the option to download a
driver automatically from the Internet, you can
download one manually before you run the
installer. The HP support site at
http://www.hp.com/cposupport/software.html
has current drivers for most HP printers.
●You may be able to find the driver on your
operating system disc. If the operating system
is more recent than the printer, it probably
includes a driver for that printer.
file:///C|/Bottlecap_Structure_26--TestMerge/DOCS/EN/NETBASIC/FIP0020.HTM (3 of 4) [5/20/2003 3:45:36 PM]
Network Basics
●If you previously had a direct connection from
your computer to the same printer, or a
network connection to another printer of the
same model, the network printer installer may
be able to use the driver that is already on your
computer.
The installer software takes the driver location you
specify, finds the driver, and installs it in your system.
Once the installer has finished, you are ready for
network printing from your computer.
The End
When installing the network printing software, some
users are unsure when the installation is complete.
When the network printer is installed on your
computer and you can print to it, the installation is
complete.
Confusion sometimes arises in the situation when you
have two CDs -- a printer CD and the HP Jetdirect CD
-- and you have just finished the installation from the
printer CD. It is common to wonder whether you
should run the installer on the Jetdirect CD as well.
You don't need to. Once your network printer prints
successfully, you're done with the installation on that
computer. (Of course, if you are installing the
network printer software for peer-to-peer printing
from several computers, you will need to run the
installer from each computer.)

INSTALLING A NETWORK PRINTER
DETAIL
Printers that include the network installer
Many newer HP printers (January 2000 or later), including multifunction peripherals (MFPs)
and All-in-One devices, include network installation software on the printer CD. If your
printer is in the list below, use the printer CD for installation.
HP LaserJet 1200
HP LaserJet 1220
HP LaserJet 2200
HP LaserJet 3300 series
HP LaserJet 4100 series
HP LaserJet 9000
HP LaserJet 9000MFP
HP Business Inkjet 2280
HP Color Inkjet cp1160
HP Deskjet 5550
HP Officejet D series
If your printer is not identified above, or you cannot locate your printer’s CD, you should:
●First, locate your printer's driver. (The summary on the preceding page should help
you.)
●Then, run the installer from the HP Jetdirect CD.
Note that if you use the HP Jetdirect CD for MFP or All-in-One devices, some features other
than printing (such as scanning and faxing) may not be accessible. Use the printer CD to get
all features.
Note: An HP Web Jetadmin CD-ROM may also be included with selected HP JetDirect
products. HP Web Jetadmin is a feature-rich printer management tool. However, it is not
required for network printer installation.
Installing a network printer is quite straightforward:
●First, you set up your hardware. This involves setting up your printer, and
then setting up a print server to connect the printer to your network.
●Then, you run the network printing software to install the printer on your
computer.
If you have purchased your printer and print server separately, you probably have
two sets of documentation and two installation CDs -- which do you use? The
section below on
Which CD do I use? should help you get started in the right place.
In addition, sometimes it's not immediately apparent where to find the printer
driver that the installer needs. The section below on
Where do I find the printer
driver? provides some useful pointers.
Finally, the section below on
When do I stop? answers questions about when the
installation process is complete and whether, if you have two CDs, you need to use
both of them.
If you would like a brief overview of what networks and network printing are
about, along with some additional detail on the installation process, click here for
The Network Basics Tutorial.
Which CD do I use?
If you have both a printer CD and the Jetdirect CD, the steps below will help you

decide which one to use.
Step 1: Is the print server's network connection wireless or wired?
● Wireless: Go to step 4.
● Wired:Go to step 2.
Step 2: Is the printer on the following list?
HP LaserJet 1200
HP LaserJet 1220
HP LaserJet 2200
HP LaserJet 3300 series
HP LaserJet 4100 series
HP LaserJet 9000

HP Officejet D series
● No: Go to step 3.
● Yes: Use the printer CD. (It knows where to find the printer driver.) When
prompted, select the network connection option.
Step 3: Is the printer an MFP (multifunction printer) or an Officejet Allin-One printer?
● No: Go to step 4.
● Yes: Use the printer CD to install the printer as if it were connected directly
to your computer; this will install the printer driver on your computer. (You
don't need to make any physical connection with a printer cable; just specify
"parallel" when asked for the port.) Then use the Jetdirect CD to install the
printer as a network printer. (This will use the printer driver that you just
installed on the computer, and will set up the print path to the printer via
the network.)
Note: Only the printing function will be available over the network. Other
functions, such as scanning and faxing, will not be available over the
network.
file:///C|/Bottlecap_Structure_26--TestMerge/DOCS/EN/NETBASIC/START.HTM (2 of 5) [5/20/2003 3:46:12 PM]
Network Basics
Step 4: For other HP printers or non-HP printers:
Use the Jetdirect CD to install the printer on your network. (You will need to know
where your printer driver is located. See
Where do I find the printer driver? for
more information.)
Note: An HP Web Jetadmin CD-ROM may also be included with selected HP
Jetdirect products. HP Web Jetadmin is a feature-rich printer management tool.
However, it is not required for network printer installation.
Where do I find the printer driver?
At some point late in the installation, the installer software needs to have the
printer driver to complete the installation. So at that point the installer may ask
you where to find the driver. Knowing where to find the driver is usually the most
subtle part of the installation.
If you are running the installer from your printer CD, the installer generally knows
right where to look for the driver -- on the CD. If you are running the installer from
the Jetdirect CD, the installer will probably need you to tell it where the driver is.
Here are a few places you can look:
●The best source of a driver for your printer is the Web, because that gives
you the latest driver. (The drawback of getting your driver from the Web is
that some drivers are quite large, and may take several minutes to download
at modem speeds. We think it's worth spending the time.) The HP support
site at
http://www.hp.com/go/get_software has current drivers for most HP
printers.
If your printer is an HP printer and you are running the installer from the
HP Jetdirect CD in the Autoconfigure network settings for me mode, you
can select the option to download a driver automatically from the Internet.
The installer will search the HP support site for a driver for your printer and,
if it finds one, will automatically download it and install it for you. If you
don't select the option to download a driver automatically from the Internet,
you can download one manually before you run the installer.
file:///C|/Bottlecap_Structure_26--TestMerge/DOCS/EN/NETBASIC/START.HTM (3 of 5) [5/20/2003 3:46:12 PM]
Network Basics
●In many cases the driver is the same one that is used for a direct (non-
networked) printer connection, and you can probably find the driver on the
CD that came with the printer.
In technical terms, what you need is a driver that installs using a .INF
information file (rather than installing by running a .EXE file). Make sure
that your driver files include the .INF file. (If you can't find the printer's .INF
file, you may have to download the driver from the Web.)
●You may be able to find the driver on your operating system disc. If the
operating system is more recent than the printer, it probably includes a
driver for that printer.
●If you previously had a direct connection from your computer to the same
printer, or a network connection to another printer of the same model, the
network printer installer may be able to use the driver that is already on your
computer.
The installer software takes the driver location you specify, finds the driver, and
installs it in your system.
When do I stop?
Essentially, you are finished with the installation process when you have a network
printer installed on your computer and you can print to it. That's usually when the
test page prints successfully.
If you have two CDs -- a printer CD and the HP Jetdirect CD -- and you have just
run the installer from the printer CD, it's common to wonder whether you should
be running the installer on the Jetdirect CD as well. ("After all, that second CD
must be there for a reason. Maybe I should run that installer, too, just to be sure. . .
.") You don't need to do that. Once your network printer prints successfully, you're
done. (We put the installer on the Jetdirect CD for situations where you can't find
your printer CD, or where the printer CD's installer doesn't deal with network
printers. If your printer CD does handle network printers, just run that installer
and stop when it's done.)

General information
on the HP Jetdirect 280m print server
General description
The HP Jetdirect 280m is an LIO print server module. That is, it plugs into the LIO
slot of certain HP printers and provides network connections for those printers.
Formally speaking, it is:
J6044A
HP Jetdirect 280m 802.11b internal
wireless print server
This print server connects to 802.11b wireless networks.
The print server includes an embedded Web server that allows remote
management through a Web browser.
Compatibility
This print server connects to wireless networks that are compatible with the IEEE
802.11b standard. It can connect to devices on such networks either directly ("ad
hoc" or "peer-to-peer" mode) or through a wireless access point ("infrastructure
mode"). It can also connect through an access point to wired Ethernet networks.
file:///C|/Bottlecap_Structure_26--TestMerge/DOCS/EN/280M/USER/LWGINFO.HTM (1 of 3) [5/20/2003 3:49:29 PM]
HP Jetdirect 280m user's guide
The 280m print server supports both peer-to-peer and client/server printer
networking under TCP/IP; peer-to-peer printer networking under IPX/SPX (direct
mode), Apple EtherTalk, and lpd printing; client/server IPX/SPX printer
networking under Novell NetWare; and DLC/LLC, FTP and IPP printing. These
protocols are, in various combinations, supported on these operating systems:
Windows (98, 2000, ME, NT 4.0, XP, and XP 64-bit), MacOS, Novell NetWare,
IBM OS/2 Warp, HP-UX, Solaris (on SPARC systems), SCO UNIX, IBM AIX, MPEIX, and Artisoft LANtastic. See the section on Specifications for details of which
operating systems support which protocols.
The Jetdirect 280m print server supports both 40/64-bit and 128-bit WEP
encryption. In addition, it supports several 802.1x authentication protocols: LEAP,
PEAP, EAP-MD5, EAP-TLS, and EAP-TTLS.
The embedded Web server, which allows you to monitor and manage the print
server remotely, requires Microsoft Internet Explorer 5.0 or later, or Netscape
Navigator 4.75 or later.
See the
Specifications section for more details on the print server.
Nomenclature
The main parts of the print server are shown in the illustration:

Installation
There are two parts to installing the print server: hardware installation and
software installation. You should install the hardware first.
Hardware installation
1. Set up the printer hardware. Do not connect the printer to your
computer with a USB or parallel cable.
2. Switch on the printer's power.
3. Plug in the print server. Push it into the LIO slot on the back of the
printer until it clicks into place.
4. Print a configuration page by pushing the Test button ( icon) on the print server. If the page does not print successfully, see the
troubleshooting section.

1. Configure the wireless printer to communicate on your network.
You will use the HP Jetdirect Wireless Setup Wizard for this task. (This step
puts the printer on your wireless network. It is functionally equivalent to
plugging the network cable into a printer on a wired network.)
a. Choose a wireless computer from your wireless network.
During the configuration your computer will be communicating with
the wireless printer in ad hoc mode, which involves direct wireless
communication between the computer and the printer (without going
through a wireless access point).
b. Make a note of your computer's wireless settings. You will
configure these settings onto the wireless printer.
■Mode (network type): Ad hoc (peer-to-peer) or Infrastructure
(using a wireless access point)
■ Network name (SSID)
■ Encryption and authentication settings
c. Insert the HP Jetdirect CD into the wireless computer's CD-
ROM drive. (If the CD does not automatically start, run SETUP.EXE
from your CD-ROM drive.)
You will use the Wireless Setup Wizard on this CD to:
■change the wireless settings on your computer to communicate
with the wireless printer
■download the new network configuration to the printer
d. Run the Wireless Setup Wizard. From the CD's opening screen:
Click "Install".

The Wizard will establish communication with the printer. It will try
to change your computer's wireless configuration so it can talk to the
printer. If it can't do this automatically, it will ask you to do it
manually (using your wireless card's configuration utility or using the
built-in functions of Windows XP).
When the Wizard finds the printer, it will ask you for its new
configuration parameters. You will supply these from the information
you wrote down in step 1b, above. The Wizard will then download the
new configuration to the printer. At this point the printer becomes
part of your wireless network.
Finally, the Wizard will try to change you computer back to its
original wireless configuration, so it can talk on your network. If the
Wizard can't do this automatically, it will ask you to do it manually.
2. Configure the computer to print to the printer. You will use the HP
Jetdirect Install Network Printer Wizard for this task. This step installs the
printer driver on the computer and sets up the print path from the computer
to the printer.
a. Run the Install Network Printer Wizard. When the Wireless
Setup Wizard completes, you will return to this screen.
Since the printer is now configured, this
time choose "Yes", and on the next screen choose

"Step 2 -- Install the printer on this
computer". The Install Network Wizard will start. Follow the
instructions on the screen to configure your computer to print to the
newly installed wireless printer.
You will need to have your printer driver available for installation. If
you don't have the driver, you can get it from the Web at
www.hp.com. If the driver is already on your system (from a directly
connected printer), the installer software can use that driver.
b. Configure other computers on your network. Run the Install
Network Printer Wizard on the other computers on your network to
configure them to print to the new printer. To run the Wizard:
■Insert the HP Jetdirect CD into the computer's CD-ROM drive.
(If the CD does not automatically start, run SETUP.EXE from
your CD-ROM drive.)
■ On the opening screen, click "Install".
■ Select "Wireless", then click "Next".
■ Select "Yes, the wireless settings have been configured . . .",
then click "Next".
■Select "Step 2 -- Install the printer on this computer", then
click "Next". This will start the Install Network Printer Wizard.
Note: If you have a large network and are setting up a client/server
printing environment, set up the wireless printer as you would any
other (wired) network printer.

Quick Checks
Here are a few common problems, and some possible corrections:
●Problems during installation
1. Computer can't communicate with wireless print server during initial configuration. The Wireless Setup Wizard expects
your compter to match the print server's factory default wireless
configuration:
■ Mode: Ad hoc (peer-to-peer)
■ Network name (SSID): hpsetup
■ Encryption: disabled
Make sure you are running the Wizard from a wireless computer, and
that your computer matches these settings. (Use your wireless card's
configuration utility or
Windows XP to check and change these
settings.)
2. Wizard does not discover printer. Print server may not be set to
factory default configuration, so Wireless Setup Wizard will not find
it. Reset print server to factory default configuration (
click here for
procedure).
3. Test page does not print.

■Make sure that you reconfigured your computer at the end of
the Wireless Setup Wizard. When you use the Wizard, you start
by changing your computer's configuration so it can talk to the
unconfigured print server. At the end of the Wizard, you must
change your computer's configuration back to its original
settings, so it can talk on your network. The Wizard tries to
make those configuration changes for you, but it can't make
them in all cases. If you had to make the first set of changes
manually, you will also have to make the second set of changes
manually. (Use your wireless card's configuration utility or
Windows XP to check and change these settings.) If you didn't
reconfigure, your computer is not on the same network as your
printer, so it can't print to it.
■Make sure that you completed both the Wireless Setup Wizard
and the Install Network Printer Wizard. The first puts the
computer on your network, the second sets up the print path
from your computer to the printer.
●Problems during normal operation
1. IP address of printer changed. If your printer gets its IP address
from a DHCP server -- including a residential gateway -- and the print
server's power is removed (print server unplugged or printer power
unplugged), the print server may receive a new IP address from the
DHCP server when its power is applied again. In that case, computers
printing to the printer's old IP address will not be able to find the
printer. Use the Install Network Printer Wizard to re-install the
printer on each of the computer on the network. Also consider
assigning a static IP address to the printer, if possible, to prevent
recurrence of this problem. (If you're going to change to a static IP
address on the printer, do that before you re-install the printer on the
computers.)
2. Network security configuration changed. If your network
administrator changes your network's encryption keys periodically to
increase network security, make sure that you change the printer's
keys when the network's keys change. (If the network access point
and the computers change but the printer does not, the printer is no
longer on the network.)
If these quick checks don't point to your problem, use the full diagnostic
procedure, below.

HP Jetdirect troubleshooting
Check the Status light.
Check the Status light on the print server. In the table below, click on the
description that matches the light's behavior.
The print server is not receiving power. First, make sure that the printer is
operating properly. Check these items:
●Is the printer plugged in and switched on? Make sure that the printer
is plugged in and switched on. If your printer has a front panel display, it
should not be blank. If you have checked these items and the printer still
shows no sign of being on, you may have a defective power cable, power
source, or printer.
●Is the printer online? The ONLINE or POWER light should be lit. If it is
not, press the appropriate key (such as ON LINE or GO) to place the printer
online. If your printer has a front panel display, check that is says "Online"
or "Ready".
●Is the FORM FEED light on? If your printer has a FORM FEED light and
it is on, it may indicate that a print job is waiting to be printed. Take the
printer offline (if necessary), press the FORM FEED key, and then put the
printer back online. If a print job starts (or continues) to print, wait for it to
complete.
After looking through the list above and making any necessary
changes, is your printer on and online now?
The printer appears to be working. Next, check these items:
1. Check that the print server is seated firmly in the printer's LIO slot.
2. If that doesn't cause the Status light to come on, remove and re-insert the print server, as follows:
a. Grasp and press the latch buttons (one on each side of the print
server) and pull the print server out of the printer's LIO slot.
b. Re-insert the print server into the LIO slot, making sure that it seats
firmly in the slot and that the latches click into place.
Note: When you first apply power to a normally operating print server (by
plugging it in to the printer's LIO slot), the Status light will slowly blink green for
several seconds during self-test. When it has completed self-test, it will continue to
blink green until it establishes a valid network connection. Once the print server
connects to a network, the Status light will go ON solid green, or will flicker
intermittently to show network activity; this indicates that the unit is ready for
operation.
After checking the items above and making any necessary changes, is
the Status light now on (any color, any blink pattern)?
If Yes, click on the Yes button to return to the start of the troubleshooting
procedure and evaluate the current state of the Status light.
If No, your print server may be faulty. Fixing such a fault requires assistance from
HP Jetdirect technical support; click on the No button for information on
contacting HP.
There appears to be a printer error. Please refer to your printer manual for further
information on how to correct the error, or for information on how to contact
Hewlett-Packard technical support if you can't correct the error. (Note that your
printer manual may be either printed on paper or stored electronically on a CDROM.)
After you have resolved the printer error, if you still have problems connecting the
printer to the network you can restart this troubleshooting utility. Click on the

Configuration page does not print, or is
unreadable.
If the configuration page does not print successfully, try the steps below.
1. Make sure that the printer and the print server are powered on.
2. Make sure that the printer is Online or Ready.
3. It may be necessary to re-initialize the connection between the printer and
the print server by cycling power on the print server. (Unplug the print
server from the printer; then plug it back in.) Do this with the printer
switched ON.
Can you now print a Jetdirect configuration page?
If yes, click on the Yes button to continue.
If no, your print server has a problem that requires assistance from HP Jetdirect
technical support; click on the No button for information on contacting HP.
The Status entry near the top of the page gives a good first indication of the state of
the print server. Other entries provide additional detail. Refer to the page on
Interpreting the configuration page for detailed information on the meanings of
the entries.
Are there error messages on the configuration page?
Fix any errors for which solutions are apparent. The page on Interpreting the
configuration page may provide useful information.
If you fix any errors, then cycle power on the printer, as follows:
● Switch off the printer.
● Unplug the printer's power cord.
● Plug the power cord back in again.
● Switch on the printer.
(This prodecure is recommended because many printers maintain power for fast
warm-up even when the power switch is switched off. Unplugging the power cord
ensures that power is removed from the printer.)
Did you make any changes?
If yes, click on the Yes button to go back to the beginning of the troubleshooting
procedure.
If no, your print server has a problem that requires assistance from HP Jetdirect
technical support; click on the No button for information on contacting HP.
Check that the computer (from which you are attempting to print) is on your
wireless network. Can your computer communicate with other computers or
printers on your wireless network?
(If the HP Jetdirect Wireless Setup Wizard did not automatically switch your
computer's wireless configuration when it completed, your computer may still be
configured for the "hpsetup" network. If so, you will need to change the computer's
configuration manually so it can communicate on your wireless network.)
You can check (and change) your computer's wireless configuration using the
setup utility that came with your computer's wireless card, or
using the
configuration utility that is part of Windows XP.
Is your computer communicating on your wireless network?
1. Use the wireless setup utility that came with your computer's wireless card,
or the configuration utility that is part of Windows XP, to change the computer's configuration so that it can communicate on your wireless
network.
2. Then run the Install Network Printer Wizard to configure your
computer to print to the wireless printer. If the computer does not find the
wireless printer, run the Wireless Setup Wizard instead, and then run the
Install Network Printer Wizard.
❍To run the Install Network Printer Wizard, insert the HP Jetdirect CD
into your computer; select "Install"; select "Wireless"; select "Yes, the
wireless settings have been configured . . ."; and select "Step 2 -Install the printer on this computer".
❍To run the Wireless Setup Wizard, insert the HP Jetdirect CD into
your computer; select "Install"; select "Wireless"; select "No, the
wireless settings have not been configured . . ."; and select Step 1 -Configure printer's wireless settings".
Is the printer on the same network as the
computer?
The solid or flickering green Status light on the print server indicates that the
printer is connected to a wireless network, but it doesn't ensure that the printer is
connected to the right wireless network.
Check your printer's wireless configuration by looking at the configuration page
you recently printed (or simply print another one). Compare the printer's wireless
configuration to the wireless configuration of the computer. Check these
parameters:
●Mode of operation: ad hoc (peer-to-peer) or infrastructure (through a
wireless access point)
● Network name (SSID)
● Encryption configuration
● Authentication configuration
(If the computer you are attempting to print from is not a wireless computer but is
on a network that is connected to your wireless network, check that the printer's
configuration matches the configuration of a wireless computer on the wireless
network.)
Note:
If the printer's wireless configuration is:
● Mode: ad hoc (peer-to-peer)
● Network name (SSID): hpsetup
● Encryption/authentication: disabled
then the print server is set to its factory default configuration and needs
to be configured. In that case, exit this troubleshooting procedure and
run the Wireless Setup Wizard and the Install Network Printer Wizard.
(Start by inserting the HP Jetdirect CD into your computer. When the
main screen comes up, select "Install"; then select "Wireless"; then select
"No, the wireless settings have not been configured . . ."; then select
"Step 1 -- Configure printer's wireless settings".)

Reconfigure your printer.
Your wireless printer is not properly configured to communicate on your wireless
network. Exit this troubleshooting procedure and take the following steps:
1. Reset the print server to its factory default configuration. (
Click
here for instructions.)
2. Run the Wireless Setup Wizard and the Install Network Printer Wizard. To start the Wireless Setup Wizard, insert the HP Jetdirect CD
into your computer. When the main screen comes up, select "Install"; then
select "Wireless"; then select "No, the wireless settings have not been
configured . . ."; then select "Step 1 -- Configure printer's wireless settings".
Does your printer get an IP address via DHCP or
BOOTP?
Some printers get a network address dynamically, via DHCP -- including most
residential gateways -- or BOOTP.
Does your printer get its address via DHCP or BOOTP?
If your printer gets its address dynamically, click Yes.
If your printer uses a static address, this troubleshooting procedure has gone as far
as it can go. You will require further assistance from HP technical support to
isolate the problem. Click No for information on contacting HP technical support.
If you have set up your printer to have an IP address (rather than an address from
some other communication protocol, such as IPX or AppleTalk), does that address
actually exist?
Check the TCP/IP section of the Jetdirect configuration page to see whether an
address (other than 0.0.0.0) has been assigned to your printer. Make sure that the
address is a valid address for your network's addressing scheme.
It is possible for the printer's IP address to change if the printer gets its address via
DHCP and its power gets switched off -- when the power comes back on and the
printer requests an address from the DHCP server, the server may give it a
different address from the one it had before.
If the printer's IP address has changed, then a computer that tries to print to the
old address will not be successful.
Check the address of the target printer in the printer control panel of the computer.
Is the IP address for this printer in the computer's printer control
panel different from its address on the printer's Jetdirect
configuration page?
