Digital BW, The Print

I have bought one of these printers because no C82 porinters were 
available in the u.K. So far I have used it with the original inks
in greyscale and also in Black Only printing. Has anyone else
tried it? I was hoping to use it for quadtones like the 870.
Is there any hope of suitable curves for it? Or would the curves
for the C82 work? The B.O. prints I have made so far on it seem 
very good to me. Thanks for your advice.
Serena.
