Digital BW, The Print

Are there any other settings you need to adjust to get this to work?
Because printing a BW image in RGB mode here on my 2100 produces an
image with a strong color cast and metamerism. I've tried almost all
possible combinations of printer-setting on BW images in RGB mode in
mye search for the best results, and so far all of them had color-cats
and metamerism.
