Let's be real, if they are going to be hiring you, they will have your SSN, full name and address etc. All of this data is much more useful to wrongdoers and surely stored is a less secure way. In addition, for most purposes other than a full backround check, your SSN, address and full name are all you need to dig up all sorts of information. I have used a fingerprint scanner for a college job once, and it was nothing fancy, just matched some fingerprints to what we trained it on. Furhtermore, if someone were able to lift a digital copy of your fingerprint from the device, whta could they do with it? Most places that use fingerprint encoding for access will require you to scan on the spot with a real finger. I would think they would notice if someone was trying to use a print-out or someone else's finger. Save your breath for bigger issues.
