Glossary
Bonjour
Bonjour is a networking protocol that uses IP but requires no configuration. You can use Bonjour to connect
your printer to a network if you are running Mac OS.
Gateway
A gateway is a device that is used to provide connectivity between networks; for example, to connect two
physically different networks, to manage the subnets inside of a network or to connect a network to the Internet.
If there are no such devices on the network, the gateway field in the network configuration should be set to the
same value as the IP address, then the Jetdirect card can act as its own gateway.
Hardware address
Every hardware component that is to be connected to a network (network card, Jetdirect print server, and so on)
has a fixed hardware address, which is set during the manufacturing process; it cannot be changed and it
distinguishes all network devices from one another. It is a number of 12 hexadecimal digits.
IP address
An IP address identifies a device in a TCP/IP network. It is composed of four bytes that can each take a value of
between 0 and 255 (inclusive).
Example: 15.180.32.45
IP addresses can be changed, so it is possible to have two devices with the same IP address. If two devices in
the same network have the same IP address, there will be conflicts, so special care must be taken when
configuring the IP parameters for the network devices. Jetdirect cards come supplied with the IP address
unconfigured, to avoid conflicts with other devices in the network. When the network card is first connected, it
takes the IP address value 0.0.0.0. After a few minutes of being connected, the IP address changes to the
default and non-valid value 192.0.0.192.
Subnet mask
The IP address of your printer contains sections that identify the network, the subnet, and the host within the
subnet.
The subnet mask is used to separate and identify the bits of the IP address that are used for every section. Two
devices that use different subnet masks won’t see each other even if they are physically connected to the same
network. So the subnet mask has to be configured carefully and by following the instructions of your network
administrator.
Example: 255.255.248.0
Syslog server
A syslog server is a device in the network that can receive and process status and error messages from the rest
of network devices. If there is no syslog server on the network, it is recommended to set this value to 0.0.0.0 in
order not to generate unnecessary traffic on the network.
