WHEN YOU NEED A DIGITAL VERSION OF A PRINTED DOCUMENT TO STORE ON YOUR COMPUTER OR TO USE ONLINE, A SCANNER IS WHAT YOU REQUIRE.
If you have a printed document that you want to keep a copy of in your computer or want to email to your friends, you’re going to fall back on a scanner. It makes a digital copy of the document. A scanner shares some things in common with a photocopier.
A scanner analyses an image and processes it. Image and text capture (optical character recognition or OCR) allow you to save information in a file on your computer. You can then either modify the file or print it according your needs. Scanners have a true hardware resolution of at least 300x300 dots per inch
