Digital BW, The Print

Hi to everybody.

I just received my R220 but I'm not able to find the "black only"
option in the driver dialog!
I have only a "grayscale" option that seems to use the color inks to
produce grayscale prints.
Does anyone can help me? Can you tell me the correct driver version? I
use the 5.5 that was in the box.

Thanks for your help and best regards.
