a NE sends data out over its ASCII printer interface, the data is first spooled by the IP-
SPOOL application for a user-defined capture interval. The spooled data is then forwarded
to the shared printer. Similarly, to allow the 3270 clients to continue to print via the IP-
B2APRT application, the latter now has a connection to its own virtual printer – a different
IP-SPOOL instance. This IP-SPOOL application instance forwards data to the same
shared printer.

The IP-SPOOL application takes advantage of the DT-6XXX redundancy infrastructure (an
optional 1+1 spare arrangement) to enhance its reliability. Should a DT-6XXX fail, the
spare immediately takes over automatically, and assumes the public IP address of the set.
It should be noted that applications do not need to change, or even be made aware of
whether the DT-6XXX is operating in duplex or simplex mode. Refer to the
DT-6061
Platform User’s Manual
for more information.
