T here are two worlds out there on the desktop.
The first is the digital world, full of the letters, graphics and spreadsheets that you create on your computer and transmit electronically. Or maybe you'd like to fax a copy of a magazine article to the home office, but your fax-modem will only handle items stored on your computer. With a scanner, the computer world meets the paper world. Scanners digitize printed images. That means they turn documents into patterns of digital 1s and 0s that your computer can store, edit and transmit.
