Appellate Practice Attorney serving New York, NY
The question is not whether it is legal (I know of no reason why it wouldn't be), but the more practical one of whether the recipients of the documents will accept photocopies or will require originals. To ensure that this problem doesn't arise, it is standard practice to include a clause in stipulations or other agreements that copies or printouts from electronic files are treated the same way as originals.
