Both workstation and mainframe platforms may be connected to
the 4890 through a local area network (LAN).

module
The 4890 supports XNS protocol on an Ethernet LAN. Other
types of networks and network communication protocols are
supported through the addition of a communication module or
front end processor.
It is possible to have more than one type of interface connected
to the printer simultaneously. For example, your facility could
have both an online and an Ethernet connection to the same
printer.
Online jobs use the online (channel) interface and are processed
directly by the input task. All other inputs are processed by the
host interface processor (HIP) task; the Barr/SNA bisynchronous
communication model jobs using the OEM interface, jobs using
the Ethernet interface, and XPAF jobs using the online interface
are all processed by HIP.
HIP can receive jobs only from one input source at a time. For
example, if your facility has both a XPMF-VMS interface and an
Ethernet connection to the same printer, HIP can receive input
from only one of them at any given time. Switching HIP from
one input source to another requires an operator command.
HIP can spool jobs from one of its input sources while input is
processing online jobs. To print these spooled jobs, the
operator must first take the printer offline and then issue a start
command for HIP to begin printing.
For further information on using HIP, refer to the Xerox 4890
HighLight Color LPS Operator Guide.
