  Actually, I'd be interested in the same thing.  With a simple SCSI -> parallel
interface converter, I would think the speed would be slow.

  The application I have in mind is: dumb laser printer, with SCSI interface, 
uses peer->peer communications to grab a bitmap (large) file directly off
a disk, and sends it directly to the laser in the printer.

  That way, I get high speed printing, from a previously spooled bitmap file,
without CPU intervention to get it off disk, and send it to the laser printer.
I also believe this makes the interface cheaper, since little to no intelligence
is required in the interface.  And it's hell-for-fast!

  Does the Apple Laserwriter (dumb version) do it this way?
