Sane is not an application, it is a library, so I doubt you are using
Sane directly. There are various applications that use Sane to scan.

Part of the Sane or libsane Ubuntu packages are xsane (GUI),
scanimage, scanadf (both command-line) and xscanimage. I have a
personal interest in gscan2pdf, which is a separate package.

gocr is a command-line OCR application. There are various others,
e.g. tesseract or ocropus. None of them have anything to do with Sane,
and therefore are off-topic here.

To get decent OCR results, you need a decent scan - typically 300 or
400dpi. At what resolution are you scanning?
