  No, you don't need more hardware than the scanner and the computer
  (except a lot of patience...). You should read the documentation about
  the SANE-Standard (available at www.mostang.com/sane) and you should
  have a look at the pnm-backend. That is a kind of example-backend which
  reads a pnm image instead of driving a scanner. If you understand how
  it works, you know the basics about backends.
  Try to find out what hardware is built into your scanner and if there
  are similar devices that probably already have a backend.
  Getting information about the protocol of the scanner is mostly the
  biggest problem. If you are lucky the manufacturer releases some
  information. Otherwise you have to snoop the windows driver.

  Best wishes
