Find someone with a Betterlight system. The painting would have to be scanned in ALOT of tiny sections at a high resolution and then stitched together to create an EXTREMELY large file.
Of course, I'm sure she wants it printed in one piece, right?
Someone with an 11880 could print 2 halves of about 45 x 120.
Go on line to the Betterlight site and click on the applications folder and scroll down to the owners gallery and directory. No one is currently listed in Ohio but a couple are in Illinois.
You could also post a question in the Betterlight forum.
