[sane-devel] Samsung SCX-4100 support proposal.

[ABC]

Hello Ilya,

I mean someone else can tutor you, but not me. Sorry. I only
participated becasue there was posibility xerox_mfp driver is working
for you. But it isn't.

You can start by [re]reading provided url. Section "Writing a
Backend (Driver)". Try to find out what the MS Windows driver does:
http://www.meier-geinitz.de/sane/misc/develop.html
+ http://www.sane-project.org/backend-writing.txt

Good bye. :)
