All,
Sorry if this has been covered, I couldn't find the exact answer I was searching for. I've filled out some fingerprint cards for a Form 4 for a suppressor, filing as an individual. I rolled my own fingerprints.

What do I put in the block for "Signature of Official Taking Fingerprints"? Is it just my name, or "self", or get any other person to sign it as a witness? Trying to not have to do this more than once. Thanks everyone for your input.
