NETWORK CONNECTIVITY
Sun workstations
The Sun workstation connects to an LPS through an Ethernet
interface. The equipment needed for connectivity depends upon
the communication protocol and the datastreams used. The
workstations communicate to the LPS through the Xerox
Network System (XNS) using XNS protocols.
Ethernet with XNS protocol
Communication protocols A Sun workstation can be configured to produce XNS protocol
output on Ethernet as shown in figure 4-11. This communication
protocol is acceptable to the LPS without conversion.

Laser Printing System
Sun
Datastreams If the application software you are using on your Sun produces
an Interpress datastream, then conversion is not necessary and a
front end is not required. However, if you are using an
application that produces PostScript datastreams, a front end
processor is required to convert the PostScript data into .IMG
files.
Ethernet with TCP/IP protocol
Communication protocols If a Sun workstation is connected to an Ethernet LAN using a
TCP/IP protocol, as shown in figure 4-12, the TCP/IP must be
converted on the front end processor to XNS protocols before
the data reaches the printer.
