LIOS (Linux Intelligent OCR Solution) is a one-stop OCR solution. It interfaces with a scanner, camera, PDF or image file, runs an OCR using the Tesseract or Cuneiform OCR engines, and saves the text in multiple formats, including reading it aloud in a robot voice. It sounded good, and there's a .deb package (there's also rpm packages), so I installed easily it in my Mint 17.1 by clicking on the downloaded package.

The OCR engine worked fine on whatever I threw at it with few errors, except for a 30 year old dot matrix print. Unfortunately, the program itself tends to be a "work in progress"; I haven't been able to export to PDF or text, except by highlighting text and cut-and-paste. Some of the other buttons will simply crash it.

The version I tried, 1.9.2, was released December 8, 2014, and version 2 will be releaased "soon", so this bears watching because it shows promise.
