When using Print&Share, you can perform Optical Character Recognition (OCR). This could for example allow you to use recognition features on scanned document. One of the options you can choose in the General Configuration is Windows OCR.
After selecting the Windows OCR option in the General Configuration, General settings nothing happens and no text is found when printing documents in Print&Share.
A possible reason could be that there are no OCR-language packs installed on your computer.
Please see our general article Windows OCR does not work describing several methods that could help you to resolve your issue.
