ARP
(Address Resolution Protocol) 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.

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
A CAB (cabinet) 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). For more information, refer to Network Printing Configurations.

Cold reset
Before a cold reset, it is recommended to 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, then press the Test button on the print server while reconnecting its power cord and 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 may erase all printer settings.

Communication Mode
The communication mode describes the type of network and protocols (TCP/IP) that will be used to print to this printer.

Default Gateway
See Gateway.

DHCP
(Dynamic Host Configuration Protocol ) Similar to BootP in that it automatically downloads an IP address from a network server. However, DHCP servers maintain a pool of IP addresses that it assigns dynamically to requesting devices and only lend 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.

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.

For HP Jetdirect print servers using direct mode (peer-to-peer) printing, different frame types on the network can be used as long as the HP Jetdirect print server has FRAME TYPE = AUTO set, and has not reconfigured itself for a specific Novell NetWare frame type on the same network.

IPsec
Short for IP Security, a set of protocols developed to support secure exchange of packets at the IP layer. IPsec supports two modes: Transport and Tunnel. Transport secures only the data portion (payload) of each packet, but leaves the IP header untouched. Tunnel mode secures both the IP header and the payload.

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 MAC (Media Access Control) address 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.

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:

PCL Printer Driver
Good for general purpose printing. You can normally select either PCL 5 or PCL 6:

PING
(Packet Internet Groper) 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 or IPX 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
Recommended for printing with Adobe or other highly graphics-intensive applications.

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, then select Settings, and 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 a test page for HP Jetdirect internal print servers, 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 Queue Object
A print queue stores print jobs until a print server transfers the job to a printer. Print queue objects are logical representations of print queues and are used to maintain information on the properties of the print queue (such as the print servers and printers assigned to service the queue).

Print Server
See HP Jetdirect Print Server.

Print Server Object
Print servers are computers or devices (such as HP Jetdirect print servers) whose function is to retrieve spooled print jobs from print queues and transfer them to printers. Print server objects are logical representations of print servers and are used to maintain information on the properties of the print server (such as the printers to be served).

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 only be prompted 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.

Wired Equivalent Privacy (WEP)
A security protocol for wireless local area networks (WLANs) defined in the 802.11b standard. WEP is designed to provide the same level of security as that of a wired LAN.

Wireless Fidelity (Wi-Fi)
Meant to be used generically when referring of any type of 802.11 network, whether 802.11b, 802.11a, dual-band, etc.

Wi-Fi Protected Access (WPA)
Improves upon the security features of WEP through the use of authentication and the scrambling of encryption keys.
