Digital BW, The Print

In his comparison of prints made using the Piezo system with those 
made using Epson drives and color inks, Michael Reichmann states 
that "what's also much more obvious when looking directly at the 
prints is that the Piezo prints show more detail. The Epson driver 
can not take an input file of more than 360 DPI. Feed it a higher 
resolution file and the data is discarded by the driver. A Piezo 
driven printer can take a much higher resolution file, and make use 
of it." Assuming that this is the case, then wouldn't the same 
condition and result apply (perhaps to differing degrees) to all 
inksets, including the various quadtone sets available, when used 
with the Epson driver rather than the Piezo driver? I guess what I'm 
wondering is just how much of a difference there is. And, yes, I'm 
sitting on the fence, Epson 1160 in hand, trying to decide whether I 
should fork over big bucks for Piezo software -- and run the risk of 
my now out-of-production printer breaking down and then having to buy 
_new_ software for the replacement printer, etc. -- or go with the 
MIS VM inkset, sweat out the paper-profile limitations...
