Saving Scanned Documents as a Searchable PDF Using Epson Scan 2
You can scan a document and save the text in a searchable PDF. In a searchable PDF, text is
recognized using Optical Character Recognition (OCR) and then embedded in the scanned original.
Note:
The required Epson Scan 2 OCR Component is installed automatically when you install your
