When I print in Gwenview, I can select "grayscale" instead of "color". However, this doesn't do anything; images are always printed in colour. In contrast, I can print in greyscale in Firefox by selecting `Print Color as Gray` =`On` using its print dialogue, which works fine. Is there a way to print in greyscale in Gwenview?

Bump. This is the print box that I'm talking about. "Grayscale" is not respected.

Third and final bump.
