Difference between Efile EAD and paper file EAD

Hi, my friends, I'm thinking of renewing my EAD card these days, but don't know the difference between EFiling and paper file. I've got an impression from this forum that you don't need to have a finger print for paper file, but for e-file, the USCIS will send you notice for finger print. Just called the USCIS, but they told me you still need to have your finger print for paper file and the only difference between them is when you got your receipt number. I'm moving in one month, and really don't want to miss the finger print notice. Can anyone help to confirm that whether paper file EAD will need a finger print? Thanks so much.
