AFAIK, OCR is only available in OneNote 2016 (i.e. through a licence or Office 365), but not in the OneNote UWP app, which you get for free in the Windows Store.
Edit:
Though, if you imported the Image/Print in OneNote 2016 you can search the OCR result in OneNote UWP and access it using Right-Click -> Picture -> Alt Text
Any chance you can tell me the steps you've used in the past to get OCR out of it? I just took like 30 photos of a book to test this idea out and can't OCR it.
