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