Digital BW, The Print

Greetings,

I am printing with the Epson R2400, both in full color and with the 
ABW. I print regularly but not in sufficient quantity to come up with 
accurate per print costs for ink. I know that several of our board 
members have probably done this. Could you possibly share with me some 
estimate figures to help me with my materials costs analysis? I have 
seen some figure this in cost/sq inch in the past. Thanks in advance 
for any help you can give me.

Scott
