Electronic Vs Hard Copy Finger Printing

How is Electronic Fingerprinting different than Hard Copy ? Do they provide a copy of Fingerprints in some form when we do Electronic fingerprinting at local Police Station or do they send that to PSI CoE directly ? I have a hard copy of fingerprinting from 2-3 weeks ago but just wondering if I should go for Electronic one.

Cleaner (obviously) and (I’m guessing) more accurate than ink. In my experience they print out hardcopies to send to various agencies.

I’m not sure about more accurate but they can tell right away if they got a ‘good’ print.
