There are lots of OCR things out there.
Some scanner software comes with it, but in my experience (which is limited and not recent) it left alot to be desired. Wasnt easy to use, and was cumbersome.
It can be done, i am sure of that, but easily, I doubt it.
What you are asking is for a machine to look (without the benefit of eyeballs and a brain) at splotches of ink and determine what is an "A", "Z" and everything inbetween.
This is why human brains are always far superior to computers.
You can see the letter "E", in 1000 different fonts and immediately recognize it as the letter "E". You can rotate it 12 degrees, flip it upside down, you still know its an "E".
A computer cant do any of this.
