DEFINE the port on the LAT to ACCESS REMOTE, AUTOBAUD DIS, AUTOPROMPT DIS,
AUTOCONNECT DIS. Set the speed correctly for the printer. Define the server
name to match it's DECnet node name. Make sure to use the DEFINE command to
load the changes permanantly. LOGOUT the port.

In LTLOAD or whatever command file you use to set up LT stuff, enter the
following on ALL systems to use the printer: 

CREATE PORT LTA100
SET PORT LTA100/NODE=node/PORT=PORT_n

This will create the port to the printer. This assumes you have not renamed
the port. Node is the nodename for the terminal server.

Then set the lines (LTAx) just as you would if the printer was directly
connected to a local port. (E.G. $ SET TERM/DEV=LN03 LTA100:)

Spool the device ($ SET DEV/SPOOL=ASDF LTA100:)

Initialize the queue ($ INIT/QUE/PROC=LATSYM/START/ON=LTA100/... ASDF

(I imagine you will not use ASDF for the queue name. That's just for the
example.)

On a cluster the /ON qualifier should include the cluster node name.

Notes:

Be sure to specify /PROC=LATSYM or the first system to access the printer will
never release it. 

When using the CREATE PORT command in LATCP, it is suggested that do not use
low numbered ports. We always start at 100. The reason is that if low numbers
(e.g. 1) are used, a race condition can occure that could cause the queue to
fail.
