Scanner software concepts
While any document scanner performs the same basic function, there are some that are designed for a specific document formats while others can accommodate a wider variety of formats. There are even document scanners that are intended primarily for business cards. An important factor to take into consideration when shopping for a document scanner is its image resolution, If you plan to use your document scanner mainly for filing text or less sensitive graphic documents, you can make do with a document scanner that has a resolution of 600 dpi or less. This resolution should be sufficient for most basic uses. In some cases, you will need a document scanner with a much higher resolution.
