Off hand, there are 2 possbilities.  The first is to get a larg printer buffer,
and the second involves changing the baud rate.  You can indeed set the
printers baud-rate to a higher value.  Don Lancaster runs his at 57Kbaud, over
the serial line, but it is unidirectional only.  I'd suggest that you could
set the baud-rate on the printer to 38.4k and try it.  you can always reset
it back.  Just use the command as it is documented in your suppliment, but
change 9600 to say 19200 or 38400 and try it.  Alternatly you can call Don
at 602-428-4073 and pick his brains.  He's fairly helpful.
