With any image that has text on it, sometimes it is desired to convert it to a editable document such as a PDF or .doc (Microsoft Word document.) The term that you are really after is called Optical Character Recognition or OCR for short. While many higher priced scanners come with some sort of OCR software, most small scanners do not. There are many different software bundles out there to do this kind of job with many different price tags. If you only plan on converting typed text to a word document then you will find free versions to under a hundred U.S. dollars. However, if you plan to convert written (by hand) text, then you will be investing a bit.
