Socket

Network socket is a software structure within a network node of a computer network that serves as an endpoint for sending and receiving data over the network. A socket is composed of the IP address and the port number. For sending print data, the port number 9100 is used by default. However, other port numbers, such as 9101, 9102 etc. can also be used. The BENS server can receive as well as send print data via a socket connection. The socket connection is established in Windows systems via the definition of a so-called Row protocol, where the value specified for the Row protocol corresponds to the port for the socket connection. The socket connection with at least one port (9100) is currently supported by all known network printers.
