Typed document? As in a document that has been written in word, printed and then you want to type on it?
Why you doing that?
There are some OCR products out there, but it's a bit of a hit and miss to be honest.
What is it you are trying to achieve, there might be an alternative?
It is a manual you wrote? Or a manual from a product? Ah no, you're a estate agent aren't you.
If it's a generic one, I am sure you can find that document online, if not, Adobe pro or similar has OCR, but the quality won't be great.
Its a training manual that I "found"
