How It Works
Token Ring network print data is transmitted as packets using a high-speed
protocol very different from the standards used by serial or parallel printers.
Each packet contains information about the sender, the receiver, how to
unpack the packet, and the data itself.
The NPS 650 acts as a station in the Token Ring network, with its own unique
address. It receives the packets addressed to it, unpacks them, and converts the
print data to a format suitable for standard printers.
It is physically attached to the network by either shielded twisted-pair (Media
Type 1/STP) or unshielded twisted-pair (Media Type 3/UTP) Token Ring
cabling. The print data can be directed to two high-speed parallel ports and
one serial port, making it possible to print on three different printers at the
same time.
Where To Use it
The NPS 650 can communicate with
PC, PS/2 and Unix systems. It supports
three different network protocols:
NetWare, Microsoft and IBM
networks, and TCP/IP. Since the NPS
650 can handle these protocols
simultaneously, it’s the ideal printer
server solution for a mixed
environment.
