Hi Alan,

I have no idea what 240DPI "limiting figure" you are talking about...since
that is certainly not printer imposed...but probably dither pattern imposed.
The Epson dither pattern may in fact have a cap at 240DPI, I don't know and
haven't run any experiments (and really have no need to)...but when using
the Epson driver in grayscale, it only uses ONE ink, the black ink...and the
dither pattern would be pretty large (look like TMax 3200, coarse and chunky
;-).  I do know, for a fact, that when using the Piezo driver, I can see
differences in prints up to over 480DPI...so that "limit" isn't part of
Piezo (or the physical printer).

Regards,

Austin
