Reverse LAT Printer woes with Ultrix 3.0 (RISC)

[todd at narnia.ecs.rpi.edu]

I have been struggling to get an Imagen laser printer to properly talk with
a DECstation 3100 through a DEC terminal server.  The printer software came
with the printer and worked fine with a VAX 780 running 4.3BSD and a serial
line.

The symptoms: A single short file prints fine.  A long file starts out OK,
then gets garbled.  If several short files are in the queue, the first one
will print fine; the latter ones are garbled (assuming anything comes out at
all).  (Note: The Imagen using the IMpress printer language, rather than raw
ascii...)  Several of us think that perhaps some sort of flow control problem
is at work.  I have set the terminal server port to use flow control, disable
flow control, etc., only to get the same results.  (Only XON/XOFF flow control
makes sense in our configuration).  I have also tried various settings of the
flags in the printcap entry.

Any ideas about what I might be doing wrong?
