Subnet Mask
With the help of the subnet mask, large networks can be split up
into subnetworks. In this case, the user IDs of the IP addresses are
assigned to the various subnetworks.
The print server is configured not to use subnetworks by default. If
you wish to use a subnetwork, you can configure the relevant
parameter via the PRINTSERVER Homepage or the
PRINTSERVER-NetTool.
TCP/IP Port
During the transfer of files between two computers, addressing with
the IP address alone is generally not sufficient. In addition to the IP
address, a port number (TCP/IP port) is used. This number defines the
computer memory area that is reserved for a specific
communications connection. The combination of an IP address and a
port number is unique for every communications connection and is
defined as a socket.
TCP/IP Ports with LPD Protocol
If the LPD protocol is used for transferring print data, the
corresponding data packet contains the pre-configured TCP/IP port
515. The transferred print data is saved to the memory area
corresponding to the port number and then processed.
TCP/IP Ports Without LPD Protocol
If the LPD protocol is not available, as in the case of Windows 98
networks, you must configure the TCP/IP port yourself. To do this,
you must install a printer port and enter the port number. In this
case, such a port may also be called a direct printer port.
