SimpleOCR engine is perhaps the most advance optical character recognition (ocr) technology in the world, their SDK is widely available for developers. The OCR software itself is free, however, it is not user friendly although it is somewhat accurate. OmniPage is by far the most user friendly OCR I’ve used, but it cost a bomb just to perform an OCR once in a blue moon.
If your documents have multi-column layouts, non-standard fonts, poor IRISPdf Server & IRISCapture for Invoicesquality or color images, you will need one of our commercial OCR applications, other than that, it is always good to use a free software like SimpleOCR, why waste money on something you are probably going to use once or twice a year?
Developers may use the SimpleOCR API to add OCR capabilities to their custom software.

To check how MS Office OCR can be implemented programmatically check:
Simplest code to OCR an image using Microsoft Office’s Imaging functionality (requires MS-Office 2007 or later, imaging components must be installed and MODI must be added to references).
private string OCR ( string fileToOCR)
{
MODI.Document md = new MODI.Document();
md.Create(fileToOCR);
md.OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, true, true);
MODI.Image img = (MODI.Image) md.Images[0];
MODI.Layout layout = img.Layout;
layout = img.Layout;
string result = layout.Text;
md.Close (false);
return result;
}
Calling function can be:
private void button6_Click(object sender, EventArgs e)
{
MessageBox.Show ( OCR (“C:\\temp\\in.tif”));
}
