Digital BW, The Print

I am having problems printing black and white with my epson 2200. When
I set the printer to color ink, the print comes out bluish and set to
only black ink, the print comes out brownish. I was told to always set
the paper to bright white watercolor, this helps a little, but then
the print is slightly bluish-greenish???? It's imperative that I print
black an white without these others tones. Please help! Any advice is
greatly appreciated.
Thank You
