You can use
the ABBYY FineReader OCR program to convert scanned documents to
editable text.
In Mac OS X 10.6/10.7/10.8, you can use ABBYY FineReader to
convert scanned documents to editable text by first using an
application such as Image Capture. Scan and save your document in
Image Capture, then open ABBYY FineReader, open the Get Images From pop-up menu, and select
File. Select the conversion option
you want to use, then select your scanned file and follow the
instructions on the screen.
Note: With Mac OS
X 10.6, 10.7, or 10.8, in addition to scanning with Image Capture,
you can download and install Epson Scan scanning software. Epson
Scan provides additional image adjustment and photo correction
features for enhancing scanned images, and provides an interface
for TWAIN-compliant OCR scanning software, such as ABBYY
FineReader.
To download Epson Scan, visit Epson's driver
download site (U.S. downloads or Canadian
downloads).
