The result of the handprinted text recognition is the following:

alt text

I have used the following settings: http://cloud.ocrsdk.com/processTextField?language=Digits&letterset=0123456789&textType=handprinted

The result of the printed text recognition contents much more errors:

alt text

I have used the following settings: http://cloud.ocrsdk.com/processTextField?language=Digits&textType=normal&letterset==0123456789+−X=()

You can test it using our C# sample code. Change the URL in the ProcessTextField method in RestServiceCliend.cs file.

Recognition errors occur due to extremely slow image resolution (72 dpi instead of recommended 300 dpi). If you increase the image resolution, probably it will be possible to recognize whole formulas (both printed and handprinted paths) using this URL:
