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