问题
I need a library that can extract text from handwritten paper once I scan it. Normal Latin text.
It can be a free solution or even something I have to pay for, as long as it handles handwriting for block letters (not cursive).

There isn't an OCR program capable of recognising hand-written text well; it's not something that can be solved easily.
There are, however, strong commercial systems which are possible to train if the variancy isn't too great. For example, take a look at ABBYY.
