Oh, it is very simple: I can't justify the expense. I have the original
paper map, and the person that wanted the copy will not complain: what
he had was a black an white photocopy. What I gave him was better than that.
Perfection is not required, but the defects took me by surprise.
In case I need a better result, I will do a photocopy at some paying
place that does A3 size at least. Or, if do it myself, take a photo with
a camera.

I will try, redoing the scans at half the resolution (300 dpi) and
keeping the orientation somehow, if possible.
