I just tried printing this on an Epson 1400 with QTR and the Epson driver.
It's very sharp with either.  The text actually looks a little larger than
the "1 point" text I had printed earlier.

I'm not sure what QTR does with a 1080 dpi file.  I think the Epson driver
downsizes it to 720.  That might actually be a source of difference that
could affect the K3 example.  I've experimented with very high resolution
files in the past and noticed that the information thrown out by the Epson
driver (I forget what printer model) made the very high resolution file
print less well than one that was "only" 720.  That is, there may be a
difference in how the approaches treat very high res files.

At any rate, while high resolution scans are wonderful, I can't imagine
anyone wanting to deal with or needing a file in excess of 720 ppi at the
print size.  The 20,000 pixel wide panorama file I just printed was such a
nuisance to deal with and print at its full resolution that I downsized to
240 ppi for the 51 inch print.
