It isn't substantially different at all. One's handwriting is one's handwriting. And the amazing thing is that it is independent of the set of muscles being used.
As a research physicist and professor, I have spent the largest portion of my life writing on blackboards, using my arm and shoulder muscles, rather than my hand and wrist muscles. Yet my large writing on the board is identical to my small writing on paper--and this holds true for all I have seen. The characteristics that define one's handwriting, are, as we physicists would say, invariant.
