[sane-devel] Canon MP460 - using MP600 experimental patch

[David Nicklay]

Hi,

I was able to successfully get an image off of the Canon MP450 scanner 
using the experimental MP600 patch.  Apparently the only settings for 
the scan command that work are color,75x75 DPI, and no offsets.  If I 
change any of these the scan command fails.

This command works:
./scan -r 75 -m color -1 out.pnm

This command fails when trying to send the scan parameters:
./scan -r 150 -m color -1 out.pnm

So apparently the printer doesn't like the changed parameters for some 
reason.......  Partial output from a debug on the last command:

[pixma-0.12.2] OUT  T=0.459 len=64
[pixma-0.12.2]  00000000:de 20 00 00 00 00 00 00  00 00 00 00 00 00 00 30

I hope that helps!
