Scanning images into your computer allows you to keep an electronic copy of them for archive purposes or to be sent to other people instantly through email, making this a useful practice for the small businessman. Many Canon printers are all-in-one printers that come with a built-in scanner and can be used for these scanning tasks. If you have a Canon all-in-one printer installed on your computer, you can use it to scan a document using the native Windows "Fax and Scan" program.
