No. Normally the output is a plaintext file. You have to add markup or
formatting manually.

Some more sophisticated OCR software may be able to guess some markup,
but IMHE it's usually wrong.

No, you just get the image.

This is unfeasibly difficult to do reliably, and I have never seen
anything that does it. As Joe says, there are some applications which
claim to do this, but I have never tried them.
