Do any of the SANE Pixma devs (I guess primarily Rolf) have any
documentation of the BJNP protocol so far as scanning is concerned?
If so, could I get a hold of a copy?
I guess I could figure it out with a code read but if someone had
something written down, then that would save me a lot of work.
No there is no documentation. reverse engineered the protocol based on
the traces of the Ip-packets.
So reading the code (especially pixma_bjnp_private.h) is the way to go.
Most communication happens using UDP, but the transfer of the scanned
data happens over TCP.
