Digital BW, The Print

It's easy to prove, with test prints, that Epson desktop models resample to
exactly 720ppi, and large format models resample to 360ppi. Here's a good
test:

	http://www.pbase.com/image/22493977

This has alternating black and white lines at 360 lines per inch (assuming
you leave the resolution set for 720ppi). If you print this on a desktop
machine, you should see gray, because it will correctly render both the
black and the white. If you change the resolution to 1440ppi and print it,
one half will come out white and the other half will come out black. If you
set the resolution to some oddball value, like 1420ppi, you'll see black and
white aliasing bands.

Some drivers have an option for "smooting edges". I believe this does some
filtering on the image to avoid aliasing, so turn this off.
