Hello!
I found some information on a project for making a driver for the
portable mp3 player made by Diamond (Rio PMP300) which uses a parallel
port for transferring music files. The interesting fact is that it is a
proprietary protocol interface so the programmers had to guess
the protocol in a unusual way.
I am including some of the documentation of the Rio driver for Linux.
I wonder if the Sane developers are using a similar approach when they
are facing a proprietary parallel port Scanner and the manufacturers
refuse to disclose information about the protocol. :-)

bye,
