Digital BW, The Print

Thanks so far, yes hopefully someone will be able to give us some 
ballpark numbers. I would really like to have a sense for what ink and 
paper costs are for a given picture. I was inspired to wonder this 
after reading Brooks Jensen's article in Lenswork on lower pricing for 
prints which I must admit was an amazing read. But, when one is selling 
at such a low price, the material costs do become a larger percentage 
of the selling price. I am just curious as to what this might be. Paper 
cost is easy to figure out. My ink usage on EPSG paper with the R2400 
is not so easy to figure.

Thanks if someone has a handle on these costs or quantity of ink used 
figures.
