Thanks to all those who responded. My problem with setting up the queue for a
plotter concerned how the form was defined.  I was embarassed to learn that
there are instructions in the GCG manual for setting up plotting queues.  If I
had followed these from the start, I would have been fine.

Michael Hogan from GCG gave me the following instructions which as he notes
also appear in the Installation section of the System Support Manual.

You don't say how your form is defined.  It sounds like this may be a "wrap"
problem.  The  form for a queued device should be /nowrap/ttsync/notruncate to
prevent interruption of the stream of graphics commands.
If this queue is sys$print you might try the following;

$ define/form/nowrap/notruncate default 0
$ stop/queue/next sys$print
$ set device/nospooled $printer
$ set terminal/perm/nowrap/ttsync $printer
$ set device/spooled=(sys$print, sys$sysdevice:) $printer
$ start/queue sys$print /on=$printer/form=default
$ assign "|print/queue=sys$print" plotport

Instructions for setting up a queue frm scratch are in the System Support
Manual (page 46 of the installation section).
