The stock Epson driver resamples everything to 720ppi for the desktop
models, 360ppi for the wide format models, and then dithers to the higher
dpi value. If you want complete control over the resampling, and don't want
to trust the Epson driver not to introduce aliasing, use an integral
subdivision of those numbers.

The old drivers used "nearest neighbor" for resampling, which was asking for
trouble. However, the most recent drivers include an edge smoothing option,
to eliminate aliasing when it upsamples. I haven't tested it to see how it
compares to other manual resampling techniques.
