The on-line service I used advised to print two copies, and to keep the second copy for when you exit Cambodia. Was not asked to produce it when I flew out; apparently they only checked for the entry stamp in my passport.
One of the previous poster was trying to fill up as much space in their passport as possible, which is why I mentioned a VOA offers a full page sticker whereas the e-visa only gives a regular-size stamp. And while it's true that the e-visa has you print out a piece of paper that is the size of a passport page, it doesn't get attached to your passport, they just collect it when you go through customs.
