[IWantOut] 30F US -> Italy

Hi everyone, I’m in the middle of getting stuff together to apply for my Italian Citizenship via Jure Sanguinis (descent). I just contacted the comune in Italy my family is from, and got my great grandfathers birth, death and marriage certificate emailed to me, stamped and signed. Does anybody know if I can just print these? Or do I need them to mail me hard copies?

Thanks a bunch.
