Digital BW, The Print

Hi Roy,

Maybe it is a driver issue between those two. Are you set up to do a 
QTR UT print on the 2200? That would settle it I guess.

Also, what do you think it is about the 1160/VM combination that 
makes it so smooth? VM only has black and three grey shades, same as 
UT, right?
