Digital BW, The Print

I am sure that my epson driver is sabatoging my ptring since I am 
not using thier ink. I am folliwing all the instructions for 
printing and changing the curves that I know of but my print still 
looks like crap. Do I need a new driver? The new inks from MIS say 
they are to be used with epsons drivers. I am Using the UT-FSN ink.
