Hi Jonathan,

Attached patch should fix the 1200 and 2400 dpi issue. This file patches
backend/pixma_mp150.c.

Please copy attached file into the folder backend/ and process from
inside backend/ this command: patch pixma_mp150.c pixma_mp150.c.patch1

Then 'cd ..' and 'make && sudo make install'.

Please report your results again.

If this patch is working, I'll update Sane's development sources.

Cheers,
Rolf
