   Piezography does know something....

   We actually are printing an uninterpolated 2160 x 2160.  EPSON doesn't
   attempt that yet!  For probably very good reasons!!

Well, that's quite interesting.  Clearly it's possible to specify
units like that with the extended ESC(U and ESC(D commands, and I know
full well that Epson manuals tend to be quite incomplete about what
parameters are accepted (I certainly don't believe that you *must* use
a base resolution of 1/1440" with the extended ESC(U, or that you
*must* use 1/14400" with ESC(D ).  I have to admit that playing with
that is awfully tempting, although I really have to push the release
along.  It needs to be done to support 2880x720 (or the much preferred
2880x1440) printers, anyway, and it would definitely improve the Epson
code to not have 1440 hard coded everywhere.

One thing I would have to wonder about, though, is whether the the
carriage positioning is really accurate enough to make that
meaningful.  If it is, then it's entirely possible that we could make
our virtual 1440x2880 mode into a real 1440x2880 mode.
