Ehm...sorry everybody, been out of town a few weeks, couldn't get my hands on
the mail....I'm back to the testing board.
I just read your posts, and wanted to sum up the steps to take. Do please,
correct me if I'm wrong:
1. Change backends/pixma_common.h around line 57 from "#ifdef NDEBUG" to
"#ifdef NDEBUGBLAAAA".
2. Same thing for backends/pixma.c line 70.
3. compile, install and test.
@Nicolas: if I understood your post below, you're suggesting I use "#ifdef
NDEBUGPIXMA", instead of the above....am I right?
