My little rant on mac scanner
If you require greater detail from your scanned images, you will have to go for a document scanner that is intended specifically for photographs. These types of scanners usually come with a comprehensive set of features that make it remarkably easy to get your images into the computer. Some of these scanners essentially serve as complete digitizing solutions, and they may come with image editing software. If you want to be able to work with the text from the documents that you scan, you will want to look for a document scanner with OCR or Optical Character Recognition capability. These types of scanners use special software that can read a page of text and convert it into a document that you can open in your word processing software.
