Security
As with other networks, security for wireless networks focuses on access control and privacy. 
Traditional wireless network security includes the use of Service Set Identifiers (SSIDs), open or 
shared-key authentication, static Wired Equivalent Privacy (WEP) keys, and optional Media 
Access Control (MAC) authentication. This combination offers a basic level of access control and 
privacy.
More advanced levels of security (such as Wi-Fi protected access [WPA] and Pre-shared key) are 
available through the printer’s embedded Web server. For introductory information about the 
embedded Web server, see Embedded Web server
. For detailed information about using the 
features, see the embedded Web server online help.
NoteIt is highly recommended that you implement a wireless security scheme (either WEP or WPA) prior 
to setup. In addition, use an antivirus program to protect against computer viruses, and follow basic 
security rules such as setting strong passwords and not opening unknown attachments. Other 
network components, including firewalls, intrusion-detection systems, and segmented networks, 
should also be considered as part of your network design. 
Authentication and encryption are two different approaches to network security. Authentication 
verifies the identity of a user or device before granting access to the network, making it more 
difficult for unauthorized users to access network resources. Encryption encodes the data being 
sent across the network, making the data unintelligible to unauthorized users. Both of these 
security methods are common on wireless networks.
Authentication
The HP installation software supports Open System authentication. More advanced forms of 
authentication are available through the embedded Web server.
A network with Open System authentication does not screen network users based on their 
identities and usually involves supplying the correct SSID. Such a network might use WEP 
encryption to provide a first level of security.
NoteShared key and server-based authentication protocols are implemented through the embedded Web 
server. For introductory information about the embedded Web server, see Embedded Web server
. 
For detailed information about using the features, see the embedded Web server online help.
Network name (SSID)
Wireless devices are configured with the name of the network to which they will connect. The 
network name is also called the SSID and identifies the ESS (Extended Service Set) that is 
normally associated with larger infrastructure networks.
The SSID should not be considered a security feature because it can be easily identified. 
However, as a network administration or management feature, it does provide basic network 
access control.
HP Jetdirect print servers support a broadcast SSID, sometimes call a zero-length or blank SSID. 
If a blank SSID is configured in infrastructure mode, the print server will attempt to associate with 
the network SSIDs detected, starting with the strongest signal. Successful association will be 
based on encryption and authentication settings.

Encryption
To reduce your network exposure to eavesdropping, establish a wireless security key for your 
network. The printer installation software supports the WEP security scheme, which hinders 
unauthorized users from accessing data transmitted over the radio waves. It is based on the use of 
a single WEP key, in which case each computer or device is configured with the same key to 
communicate on that network. 
NoteUp to four WEP keys might be used on a wireless network for transmission of data. For example, if 
you have three computers and an access point, each might be assigned a distinct key for transmitting 
data. However, the remaining keys must also be entered on each device so they can communicate 
with each other. The installation software for the HP LaserJet 1320nw printer provides the option to 
type one WEP key. If you want to use more than one WEP key, those keys must be entered into the 
printer’s embedded Web server prior to installing the software. For introductory information about 
the embedded Web server, see Embedded Web server
. For detailed information about using the 
features, see the embedded Web server online help.
Media access control address authentication
Some WLAN vendors support authentication based on the physical address, or MAC address, of 
the client Network Interface Card (NIC). In this scenario, an access point allows association by a 
client only if that client’s MAC address matches an address in an authentication table used by the 
access point. This is not configurable through the printer.
Wireless profiles
A wireless profile is a set of network settings unique to a given wireless network. Many wireless 
devices have configuration utilities that allow the device to have wireless profiles for several 
wireless networks. In order to use the printer, the printers wireless settings must match the 
computers network settings for that wireless network.
For example, a person uses the same wireless-enabled laptop at work and at home. Each network 
has a unique set of wireless settings. The person creates the following wireless profiles on the 
laptop:
●at_work: Contains the network settings for the office wireless network
●at_home: Contains the network settings for the home wireless network 
When the laptop is being used at work, the person must set the wireless profile to at_work in order 
to connect to the office network. Conversely, the laptop must be set to the at_home wireless profile 
when the person is at home and wants to connect the laptop to the home network.
NoteThe HP LaserJet 1320nw printer cannot be connected to a wired and wireless network at the same 
time.

Chapter overview
This chapter contains information that will be useful if you are installing the printer to a wireless 
network, or if you are changing printer or network settings after you have installed the printer. 
Specifically, this chapter contains a description of the printer Wireless light and the network 
configuration page, and an overview of the embedded Web server (EWS) and the HP toolbox. In 
addition, this chapter contains procedures for resetting the printer network setting and for 
switching between wireless and wired communications.
The procedure you follow for installing the printer to a wireless network depends on whether the 
network communicates through an infrastructure mode or through an ad-hoc mode. You can find 
procedures for installing the printer to a wireless network in the HPLaserJet 1320nw printer 
Wireless Start guide that was packaged with the printer. For more information about infrastructure 
and ad-hoc networks, see Wireless networking basics
. 
NoteFor maximum efficiency, HP recommends the printer be connected to a network that uses the 
infrastructure communication mode. 
NoteThe printer cannot be connected to a wired and wireless network at the same time. 
Printer Wireless light
The HP LaserJet 1320nw printer has an internal networking component that provides wireless 
connectivity. To view the status of the wireless communications, the printer contains a Wireless 
light.
●If the light is on, the printer is connected to a wireless network.
●If the light flashes, the printer is scanning for a wireless network.
●If the light is off, wireless networking is disabled.

Network configuration page
The printer includes an internal component that provides networking capability for both wired and 
wireless connectivity. This section contains a procedure for printing a network configuration page, 
as well as a description of the general network and wireless network fields that display on the 
page.
Printing a network configuration page
When the printer is in the Ready state, press and hold the Go button for 5 seconds.
or
Press the Reset button on the back of the printer. 
General and wireless network settings
NoteAll of the settings on the network configuration page should match the settings of the network with 
which you are trying to connect. If any values are different, you might not be able to connect to the 
network.
The following sections describe the various fields on the network configuration page.
General network settings
Field Description
Status Status of the printer:
●Initializing: the network is initializing.
●Ready: the device is ready to receive or transmit data.
Network 
Connection TypeNetwork mode of the printer:
●Wired: the printer is connected by Ethernet cable to an 
IEEE 802.3 network
●Wireless printer can connect wirelessly to 802.11b or 
802.11g
●Disabled: Both network connection types are disabled.
NoteOnly one connection type can be active at 
a time.
Hardware Address The Media Access Control (MAC) address that uniquely 
identifies the printer. This is a unique 12-digit identification 
number assigned to networking hardware for identification, like 
a digital fingerprint. No two pieces of hardware have the same 
MAC address.
NoteSome ISPs require that you register the 
MAC address of the Network Card or LAN 
Adapter that was connected to your cable 
or DSL modem during installation.
 
						

							10   2 Support information for installing to a wireless networkENWW
Firmware Version The internal networking component and device firmware 
revision code separated by a hyphen.
NoteYou might be asked to provide the firmware 
revision code if you call for support.
Host Name The TCP/IP name assigned by the install software to the 
device. By default, this is the letters NPI followed by the last six 
digits of the MAC address. You can also configure the device 
name through the embedded Web server.
IP Address The printer’s Internet Protocol (IP) address. This address 
uniquely identifies the device on the network.
IP addresses are assigned dynamically through DHCP or 
AutoIP. You can also set up a static IP address, though this is 
not recommended.
Manually assigning an invalid IP address during install will 
cause your network components to not see the device.
Subnet Mask A subnet is an IP address assigned by the install software to 
make an additional network available as part of a larger 
network. Subnets are specified by a subnet mask. This mask 
determines which bits of the printer’s IP address identify the 
network and subnet and which bits identify the device itself.
NoteIt is recommended that the printer and the 
computers that use the subnet mask all 
reside on the same subnet.
Default Gateway A node on a network that serves as an entrance to another 
network. A node in this instance can be a computer or some 
other device.
NoteThe address of the default gateway is 
assigned by the install software.
Config by The protocol used to assign the IP address to the device:
●Automatic (AutoIP): the installation software determines the 
configuration parameters.
●DHCP: the configuration parameters are supplied by a 
dynamic host configuration protocol (DHCP) server on the 
network. On small networks, this could be a router.
●Manual: the configuration parameters are set manually, 
such as a static IP address.
●Not Specified: mode when initializing. Field Description
 
						

							ENWWNetwork configuration page 11 DNS Server The IP address of the network’s domain name server (DNS). 
When you use the Web or send an e-mail message, you use a 
domain name to do it. For example, the URL http://www.hp.com 
contains the domain name hp.com. The Internets DNS 
translates the domain name into an IP address. Devices use 
the IP addresses to refer to one another.
●IP Address: the DNS IP address.
●Not Specified: the IP address is not specified, or the device 
is initializing.
NoteCheck to see if a DNS IP address appears 
on the network configuration page. If no 
address is shown, obtain the DNS IP 
address from your ISP. The DNS IP address 
is required for Instant Share registration, 
and can be entered through the embedded 
Web server.
mDNS Service 
NameMulticast Domain Name Server Service Name. The name used 
by Apple Rendezvous to identify the printer, which consists of 
the device name and the MAC address. 
Rendezvous is used with local and ad-hoc networks that do not 
use central DNS servers. To perform name services, 
Rendezvous uses a DNS alternative called mDNS. 
With mDNS, your computer can find and use any printer 
connected to your local area network. It can also work with any 
other Ethernet-enabled device that appears on the network.
Admin Password Status of the administrators password for the embedded Web 
server:
●Set: password is specified. You must enter the password to 
make changes to the embedded Web server parameters.
●Not Set: no password is set. A password is not required for 
making changes to the embedded Web server parameters.
NoteIf you have questions about the 
administrator password, ask your system 
administrator.
Link Config The speed at which data is transmitted over a network:
●802.11b and 802.11g: for wireless network
●10T-Full: for wired network
●10T-Half: for wired network
●100TX-Full: for wired network
●100TX-Half: for wired network Field Description

Wireless network settings
Field Description
Wireless Status Status of the wireless network:
●Disabled: the wireless 802.11b/g network is disabled when 
the wired 802.3 network is active. This is the default setting.
●Initializing: the wireless network is initializing.
●Scanning: the printer is scanning for a network name 
(SSID) on all channels.
●Ready: the printer has established an association with a 
wireless network. If the network uses authentication, the 
printer has successfully authenticated.
●Error: a network error has occurred that prevents the printer 
from associating or authenticating with the wireless access 
point. (This applies to infrastructure mode only.)
Additional explanations might include one of the following:
●No signal detected: the printer could not detect a wireless 
signal. The printer will try to recover without user 
intervention.
●Scanning for SSID: the printer is scanning for an SSID 
(network name) on all channels. The problem could be that 
an incorrect network name was entered or that the access 
point is down. The printer will keep trying to find the 
network.
●Authentication in progress: the network is trying to 
authenticate the printer.
●Authentication failed: authentication failed because of an 
incorrect user name or password, or because the 
authentication type was not recognized or accepted by the 
access point. Check the Authentication Type
 parameter to 
see whether link-level authentication or server-based 
authentication failed.
●Encryption required: encryption is required on this network, 
but is not enabled on the printer.
Communication 
ModeAn IEEE 802.11 networking framework in which devices or 
stations communicate with each other:
●Infrastructure: the printer communicates with other network 
devices through a wireless access point, such as a wireless 
router or base station.
●Ad-hoc: the printer communicates directly with each device 
on the network. No wireless access point is used. This is 
also called a peer-to-peer network. On Macintosh 
networks, ad-hoc mode is called computer-to-computer 
mode.
Network Name 
(SSID)Service Set Identifier. A unique identifier (up to 32 characters) 
that differentiates one wireless local area network (WLAN) 
from another. The SSID is also referred to as the Network 
Name—the name of the network to which the printer is 
connected. 
 
						

							ENWWNetwork configuration page 13 Signal Strength 
(1-5)The transmitting or return signal graded on a scale of 1 to 5:
●5 — Excellent
●4 — Good
●3 — Fair
●2 — Poor
●1 — Marginal
●No signal: no signal detected on the network
●: signal strength is left blank when the printer is 
scanning for an SSID.
●Not applicable: this parameter does not apply to ad-hoc 
networks.
Access Point HW 
AddressThe hardware address of the access point on the network to 
which the printer is connected:
●: the unique MAC (media access control) 
hardware address of the access point.
●Not applicable: this parameter does not apply to ad-hoc 
networks.
Channel The channel number currently being used for wireless 
communication. This depends on the network in use, and might 
differ from the requested channel number. The value is from 1 
to 14; countries/regions might limit the range of approved 
channels.
●: value ranging from 1 to 14, depending on 
country/region.
●None: no channel is in use.
●Not Applicable: the WLAN is disabled.
NoteIn ad-hoc mode, if you are not able to 
receive or transmit data between your 
computer and the printer, make sure that 
you are using the same communication 
channel on your computer and the printer. 
In infrastructure mode, the channel is 
dictated by the access point. Field Description

Authentication 
Ty p eType of authentication in use:
●Open System (ad-hoc and infrastructure): no 
authentication.
●Shared Key (infrastructure only): WEP key is required.
●WPA-PSK (infrastructure only): WPA with Pre-Shared Key.
Authentication verifies the identity of a user or device before 
granting access to the network, making it more difficult for 
unauthorized users to access network resources. This security 
method is common on wireless networks.
A network using Open System authentication does not screen 
network users based on their identities. Any wireless user can 
have access from the network. However, such a network might 
use WEP (Wired Equivalent Privacy) encryption to provide a 
first level of security against unauthorized users.
A network using Shared Key authentication provides increased 
security by requiring users or devices to identify themselves 
with a static key, which is a hexidecimal or alphanumeric string. 
This key is shared by all users of the network—that is, every 
user or device uses the same key. WEP encryption is used 
along with shared key authentication, using the same key for 
both authentication and encryption.
A network using WPA-PSK authentication provides significantly 
stronger security. It uses dynamically changing encryption keys 
through WPA (TKIP). 
NoteOpen systems shared key or WPA/PSK 
authentication is entered using the 
embedded Web server. 
Encryption Type The type of encryption in use on the network:
●None: no encryption is in use.
●64-bit WEP: a 5-character or 10-hex-digit WEP key is in 
use.
●128-bit WEP: a 13-character or 26-hex-digit WEP key is in 
use.
●Dynamic: dynamic encryption is being used with WEP, 
TKIP, or both.
WEP aims to provide security by encrypting data over radio 
waves so that it is protected as it is transmitted from one end 
point to another. This security method is common on wireless 
networks. Field Description
