The main reason for interest in SCSI is for its speed.  If you want to print
full page raster images, if you use a centronics interface, you can count on 
a transfer rate of about 5K bytes/second, or about 3 minutes per page.  (This
is 8 by 10.5 inches at 300 dpi).  If you try this with a serial connection,
well, let's not talk about it.

Now, clearly, if you eliminate white space, in favor of cursor control
commands, there is a way to reduce the overall amount of data to transfer.
But, unfortunately, what we want to print doesn't have alot of white
space always.

So that's why I'm not interested in your SCSI to serial/parallel interface.
Thanks, anyway.
