Sigh.  Having designed a few halftone system, and the associated algorithms
(and hardware), I am actually miffed that a company with the resources and
technology one would think Epson has would do such as is claimed.  In my
book, there is no need (nor is it desirable) to resample to a "fixed"
resolution.  I'm on the fence about whether nearest neighbor is good or bad,
as I seen reasons why it may in fact be good...given what they do.  But,
none the less, I certainly would have done things differently, which is
apparently what the Piezo driver does, and does quite well in my opinion.

And...I'm glad you also understand this.

Regards,

Austin
