A brainstorm on laptop scanners
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. Some document scanners are even used solely for scanning 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. For most uses that don't require too much detail, this resolution is generally more than enough. For more demanding applications however, you may want to look into a higher resolution document scanner.
