Adhoc network (Device to Device Network)
A Device to Device Network is 2 or more wireless devices connecting without the
use of a centralized base station or Wireless Access Point (WAP).
Performance on these types
of networks can degrade if more than six devices are on the network.
ARP
Address Resolution Protocol. An ARP is a TCP/IP protocol used to convert an IP address
into a physical address (called a DLC address), such as an Ethernet address. A
host wishing to obtain a physical address broadcasts an ARP request onto the
TCP/IP network. The host on the network that has the IP address in the request
then replies with its physical hardware address.
Authentication
Authentication is a wireless network security strategy. On a network with
authentication, devices use a shared key as a password and communicate only
with devices that know the key. Unlike WEP, authentication does not encrypt the
data sent between wireless devices. However, authentication can be used in
conjunction with WEP. Authentication keys and WEP keys can be identical.
BootP
A bootstrap protocol used to automatically download an IP address and other
TCP/IP parameters from a network server. When the printer (or All-in-One
device) is turned on, the HP Jetdirect print server broadcasts a boot request.
If a BootP server has been properly set up, it
transmits the parameters to the Jetdirect print server over the network. See
also DHCP.
CAB file
Cabinet file. A
CAB file has an extension of .cab and is a single file created to hold a number
of compressed files.
Client-Server Printing
Client computers send print jobs to dedicated server computers that control the
use of each printer (or All-in-One device).
Cold reset
Before a cold reset, it is recommended that you print
a test page for your printer and Jetdirect print server.
To reset HP Jetdirect external print servers to factory default settings,
disconnect the power cord, and then press the Test button on the print server
while reconnecting its power cord. Wait for the print server to re-initialize.
To reset HP Jetdirect internal print servers, perform a cold reset of your
printer (or All-in-One device) and wait for the print server to re-initialize.
(For most HP LaserJet printer models, press the Go button on the printer's
control panel while you turn on power. For other printers, see your printer
manuals.)
CAUTION: Resetting your printer might erase all printer settings.
Communication Mode
The communication mode describes the type of network and protocol (TCP/IP) that
will be used to print to this printer.
Default Gateway
See Gateway.
Device
to Device Network (Adhoc)
A Device to Device Network is 2 or more wireless devices connecting without the
use of a centralized base station or Wireless Access Point (WAP).
DHCP
Dynamic Host Configuration Protocol. Similar to BootP
in that it automatically downloads an IP address from a network server.
However, a DHCP server maintains a pool of IP addresses that it assigns
dynamically to requesting devices and lends only an IP address to the print
server. Whenever the printer (or All-in-One device) is turned off and back on
again, there is no guarantee that a Jetdirect print server will be assigned the
same IP address over time, although the DHCP server will attempt to do so.
Drivers
See Printer Driver, PCL
or PostScript.

See Cold Reset.
Gateway
A gateway is a router or computer that connects two
dissimilar networks (for example, different communication protocols, data
formatting, structures, or architectures). When networks are divided into
subnets, gateways are often used to isolate one subnet from another to control
network traffic.
On TCP/IP networks, each network device is often configured with the IP address
of the nearest gateway. If there are no gateways on the network, the IP address
of your computer is typically used.

HP Jetdirect Print Server
HP Jetdirect print servers are Hewlett-Packard network accessories that connect
printers directly to a network. Direct network connections allow location
flexibility and maximum printer (or All-in-One device) performance.
HP Jetdirect internal printer server cards are used with HP printers
that have input/output slots. Some HP Jetdirect external print servers
can be used with almost any printer that has a parallel port, while other HP
Jetdirect print servers can be used with almost any printer with a USB port.
Both types of print servers support all popular network topologies and
protocols.
INF file
An INF file has an extension of .inf and holds
information about a device. It tells the installation program what the name of
the device is, and which files need to be copied and where.
IP
address
Internet Protocol address. An IP address uniquely
identifies each device on a TCP/IP network and is typically managed by a
network administrator. Recent HP Jetdirect print servers support both
IPv4 and IPv6 addresses.
When a Jetdirect print server is powered
on, it normally tries to configure itself with a valid IP address
from a network server. If a valid IP address cannot be assigned, then
a default address will be automatically assigned. If multiple devices are
configured with the same default address, check the LAN
Hardware (MAC) Address to identify the correct device.
IP hostname
An IP hostname is a friendly (or easy-to-identify) name that can be used in
place of the printer's IP address. It can be used when a name
server on
the network has been set up to map hostnames to their corresponding IP
addresses. If a hostname has been assigned and configured on the printer (for
example, printer1.marketing.com), you can specify the hostname to
identify the printer.
IPv4
IPv4 is version 4 of
the Internet Protocol. IPv4 addresses consist of 32 bits specified in
dotted decimal notation, for example 192.168.100.250. If
a valid IPv4 address is not assigned by a network server, then the
Jetdirect print server will assign itself with either a link-local/Auto-IP
address (169.254.x.x) or a default legacy address (192.0.0.192), depending on
the network.
IPv6
IPv6 is an enhanced version of the Internet
Protocol that may eventually replace IPv4, but can coexist with IPv4.
IPv6 addresses are 128 bits long and values are specified
in colon hexadecimal notation, for example
2001:0DB8:0000:0000:0000:0000:1428:57AB. Thus, IPv6 addresses will be able
to sustain the growth of devices attaching to networks for some time. Unlike
IPv4, multiple IPv6 addresses may be assigned to the print server. While a
default link-local IPv6 address is automatically
assigned, router-based, server-based and manual IPv6 addresses can
also be assigned.
Jetdirect Password
A Jetdirect password is assigned by a network
administrator to restrict access to configuration parameters on the HP
Jetdirect print server. Jetdirect passwords are assigned using a network
management application (such as HP Web Jetadmin) or other
tools.
Jetdirect print server
See HP Jetdirect print server.
LAN Hardware, MAC, or Station Address
A hardware address, also known as a Media
Access Control (MAC) or station address, is a link-level address
that uniquely identifies each node or device on a network. As defined by the
IEEE 802.3 network standards, it consists of a 12-digit hexadecimal number (for
example, 001083123ABC). The hardware address is assigned by the device vendor.
HP assigns each HP Jetdirect print server with a unique hardware address. You
can determine the hardware address of your HP Jetdirect print server by
printing an HP Jetdirect test page. For HP Jetdirect external print servers,
the address is also included on a label attached to the print server.
Local Network
A local network is a network that does not extend
beyond routers or gateways. If your computer and printer
(or All-in-One device) are connected to a local network, then they are
connected to the same network cable segment.
NDS
Novell Directory Services. NDS is a relational database that logically organizes
network resources as objects in a hierarchical tree structure. Assuming you
have the appropriate rights, you can access these network resources regardless
of their physical location. NDS was designed to replace the Novell bindery.
Name Server
A name server is a computer on the network that is used to map (or resolve)
host names (computer or print server names) with IP addresses. A Domain Name
System (DNS) server and a Windows Internet Name Service (WINS) server are
examples of name servers.
Naming Conventions, Printer
When naming a printer (or All-in-One device), follow these guidelines:
Naming Conventions, Share Name
Based on Microsoft recommendations, names are restricted to 7-bit ASCII (the
first 127) characters. Spaces are not allowed. Follow these guidelines:
Network Name
A network name is an alphanumeric, case-sensitive
character string that provides basic access control to a wireless network. A
network name is also known as a “service set identifier,” or “SSID.”
Pass Phrase
A series of characters used for creating a Wi-Fi Protected Access (WPA) Network.
PCL Printer Driver
Good for general purpose printing. Best for most word processing,
spreadsheet, and presentations applications, such as Word, Excel, and PowerPoint.
Peer-to-peer
network
See Device to Device Network.
PING
Packet Internet Groper.
Port Name
The Port Name dialog appears only in Windows NT and Windows 2000. This dialog
only appears if "Use default port name" is not checked on the Set
Network Communication Mode dialog, and if IP communication mode is selected.
You can specify the name of
the network port to be created for the printer being installed. The port name
is used to identify the port in the printer properties.
Valid port names are up to
63 characters long and consist of any characters. The port name must be unique
on your PC. The port name is displayed on the summary screen and on the test
page.
PostScript Printer Driver
Good for specialized printing. Best for desktop publishing and graphics
intensive applications, such as Photoshop, PageMaker, and FrameMaker.
Printer
Driver
A program that controls a printer. Whenever you print a document, the printer driver takes
over, feeding data to the printer with the correct control commands. Most
modern operating systems come with printer drivers for the most common types of
printers, but you must install them before you can use the printer. You can
also download updated drivers from the printer manufacturer's Web site. See PCL or PostScript.
Printer Name
Enter a name for your printer using the appropriate printer naming conventions. This
name will be used to identify the printer icon for this printer in the Printers
folder of your system. To display the Printers folder, click Start on
your Windows Desktop, select Settings, and then click Printers.
Printer Sharing
Printer sharing allows other network users to print to this printer through
this computer. This installation utility supports printer sharing only on
Windows 2000 and Windows NT 4.0. The server service must be enabled on the
system for printer sharing. You must select one of the following options:
Printing an HP Jetdirect
test page
To print an HP Jetdirect test page, see your HP
Jetdirect hardware installation guide or your printer documentation for
instructions. For HP Jetdirect external print servers, press and release the
Test button on the print server.
Print Server
See HP Jetdirect Print Server.
Router
For a wireless network, see Wireless Access Point (WAP).
SNMP Community Name
An SNMP Set Community Name is a password that must be supplied when SNMP is
used to make a change to the printer configuration. If a selected printer (or
All-in-One device) has been protected by an SNMP Community Name or Jetdirect
password, you will be prompted for the community name. Valid community names
are up to 255 characters long.
Note: You will be prompted only when a non-default SNMP Set Community
Name has been assigned. The SNMP Set Community name can be assigned by a
network administrator using a management application (such as HP Web Jetadmin)
or other tools.
Subnet
A portion of a network that shares a common address component. On TCP/IP networks, subnets are
defined as all devices whose IP addresses have the same prefix. For example,
all devices with IP addresses that start with
100.100.100. would be part of the same subnet.
Dividing a network into subnets is useful for both security and performance
reasons. IP networks are divided using a subnet mask.
Subnet Mask
The subnet mask is the mechanism used to divide a TCP/IP network into subnets
(if subnetting is used). Subnetting
allows more efficient use of a large network. The form of a subnet mask is
similar to an IP address: n.n.n.n where n is a number
from 0 to 255. If a subnet mask has not been assigned, the subnet mask assigned
to your computer is typically used.
When applied to an IP address, the subnet mask specifies the portion of the IP
address used to identify the network/subnet, and the portion used to identify
the individual host nodes.
Note: During
printer discovery, significant performance variations can occur depending on the
speed of the system and the size of the network.
USB cable
A Universal Serial Bus (USB) cable is a common direct-connect cable option.
WEP
The original security standard used in Wi-Fi networks to encrypt the wireless network
traffic. WEP provides security by encrypting data sent over radio waves
from one wireless device to another wireless device making the data
unintelligible to eavesdroppers. Only devices that share the same WEP settings
as the printer will be able to communicate with the printer.
WEP key
A WEP key, or “encryption key,” is a sequence of alphanumeric characters or
hexadecimal digits. After creating a WEP key, you must remember it or store it
in a secure location. You may not be able to retrieve the WEP key if you lose
it. A WEP key is either 64 or 128 bits long. The first 24 bits of the key are provided
automatically. When creating the WEP key, the person creating the key provides
the remaining bits (40 bits in the case of a 64-bit key, or 104 bits in the
case of a 128-bit key).
To create a WEP key, enter the following depending on whether the WEP key is
alphanumeric or hexadecimal and how many bits it contains:
|

Wireless
Access Point (WAP)
A Wireless Access Point (WAP) is a device through which devices (for example,
computers and printers) on a Wireless Network communicate with one another. A
WAP is also called a "base station."
Wireless Network
(Infrastructure)
A Wireless Network consists of devices connecting using a centralized base
station or Wireless Access Point (WAP) to utilize commercial or public
services..
WPA-Personal (Wi-Fi Protected Access)
An improved security
standard for Wi-Fi networks that provide strong data
protection and network access control.
Wireless network hub
See Wireless Access Point (WAP).
Wireless profile
A wireless profile is a collection of wireless network
settings that applies to a particular wireless network. For example, a wireless
LAN card can have one profile for a home network and another profile for an
office network. When installing a device on a network, be sure to select the
appropriate profile.
