Bunch of places want it to "look like" you've printed the page, then signed it, then scanned it. If it doesn't "look like" that, they won't accept it. Makes no sense, but I've also encountered it a bunch of times myself too.

They're called "wet signatures"

"However, many jurisdictions still require a wet signature. For instance, in the US and Canada, notarized documents require signatures in wet ink. Similarly, documents in areas such as family law, wills, trusts, or banking also require physical signatures. In the UK, tax authorities require a wet signature for any tax documents filed by a British resident."

That's right. This requirement makes a little sense if you don't actually know the signer and could conceivably end up in court with a forensic handwriting analyst testifying whether the signature was a forgery. Anything involving notarization, for example, should pass that analysis.

But for the other 99.99% of signatures in the world, any mark at all is fine, and insisting on more is wasteful bureaucracy.
