Exactly!!!

Yeah, and that is THE image...anything that varies from that, is simply not
the image...the driver doesn't go "making up" tones that weren't there!

I understand what you are trying to say, but I claim it's simply wrong.  The
original Piezo driver doesn't print 1000 tones, period.  It simply
can't...there isn't enough discernment in the ability to print separate and
distinguishable tones anyway...  Print a 100 step step wedge, and see how
many of the tones you can separate out.  There is no way you can do that
with 1000.

Anyway, if I have a file with 256 tones, I want the printer to print 256
tones...and to discern the tones the way I want them discerned...not adding
some MORE tones where none originally existed.  So even if it could print
1000 tones, I don't want it to.

Austin
