## -A-

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.

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.
For more information see Adding Printers on Large IP Networks.
For a wireless network, see Wireless Access Point (WAP).

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.

## -I-

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.

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:

- No more than 31 characters long
- Letters A through Z, uppercase
- Letters a through z, lowercase
- Numbers 0 through 9
- Avoid characters with ASCII values less than 32 or more than 127
- Do not use commas (,)

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:

- Letters A through Z, uppercase
- Letters a through z, lowercase
- Numbers 0 through 9
- Limited special characters: $ % ' - _ @ ~ ` ! ( ) { } . ^ # & + , ; = [ ]

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.”

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. PING is a utility to determine whether a specific IP address is accessible. It works by sending a packet to the specified address and waiting for a reply. PING is used primarily to troubleshoot Internet connections. There are many freeware and shareware PING utilities available for personal computers.

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:

- Not Shared: Select this option to set up this computer for peer-to-peer printing if you do not want other network users to access the printer through this computer.
- Share as:: Select this option to set up this computer as a server for client-server printing. Network clients will be allowed to send print jobs to the printer through this computer.

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.

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.

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:

Type | Bits | Enter a string of...
alphanumeric | 64 | Five alphanumeric characters
128 | Thirteen alphanumeric characters
hexadecimal | 64 | Ten hexadecimal digits
128 | Twenty-six hexadecimal digits

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.
