'From' memory, the SCSI-2 standard (somewhat stupidly) only specifies
how to get data from scanners, and says nothing about the format of
the data itself.  (There is a field for describing the format, but
it's vendor specific).

So every scanner does things differently.  To `solve' this problem,
each scanner comes with a driver which understands the data format
(I think the name `TWAIN' has something to do with this).
