The only way I know of changing a font through scanning is by using Adobe Acrobat (full version) with character recognition, but documents done this way look really bad and it's only done to allow rapid text search.
Otherwise scanning the document is the same as copying except for resolution usually being much better on a scan.
Right, well obviously by "scan" he didn't mean scan with a "scanner", he meant some character-reading.
But that would make the signature at the bottom highly suspicious, like I said ;-)
