when I bought a Pixma MP750 more than one year ago, nobody published any
open source device driver -- not even protocol specific information. So
I decided to sniff the Windows driver's communication and analyse it.
It didn't took very long to write a dumb image acquisition tool fitting
my needs. Annoyingly my semester at the university reached its "final
stage" the same time and so the project got suspended abruptly. Shame
on me, I didn't contact sane-devel before to publish my work. I'm
really sorry for that.
When I recall correctly, the tool supported
- all resolutions: 75/150/300/600/... dpi
- user defined image offsets and sizes
- ADF and flatbed
- reset / recovery on errors
- basic status handling and
- things I might have forgotten :)
The code misses a licence (okay, that's pretty simple: GPL), credits, a
big cleanup and some comments so far. I will finalize these things on
the weekend and put the code on the net or setup public access to my
subversion repository. Maybe I will write a sane-backend some day.
If you have a Pixma scanner other than 7x0, you should consider
publishing some sniffing logs. It is pretty simple then to check if
your scanner uses a similar protocol.
