Digital BW, The Print

I've just taken my first step into B&W printing after absorbing much 
of the info in this newsgroup. Thanks everyone. I'm using Jeff 
Randalls workflow with the curves for the 740 provided in the file 
library. I'm using EAM paper. The only step in the workflow i can't 
replicate is the selection of "Matt Paper - Heavyweight" - it is 
simply not an option in my printer driver (XP). I choose "Photo 
Quality Ink Jet Paper". Is this limiting my results? If so how do I 
change my driver to get this paper option?

Thanks
