AFAIK, depends on the country and legislation. In Ireland (and Spain) I've had to produce originals where the signature was clearly hand-written (they looked for pen pressure points, for example).

I've even had kafkaesque situations where I was asked for the original of a document that was only available online. In those cases I had to present a printed copy of the document and a signed document (from the bank in this case) saying that they didn't send hard copies/originals.
