Before you try any resampling, just specify the inches and let the driver do
the resampling automatically . That almost always works fine. Explicit
resampling is occasionally useful if you have an unusual image that produces
moire, but the solution is to resample to some integral subdivision of the
printer's natural resolution, which for Epson is 720. Resampling is also
useful if you just don't have enough pixels--certain algorithms can reduce
pixelation--but that's not going to be a problem if you sample at 4000ppi.
