Scanning Photos For Printing - Photographs are nice especially if you are a professional photographer, but you could use the photos for websites to display your latest DIY project. The images could be used for desktop wallpaper or sending to friends and family through email. Because they are digitized you can use computer software to edit them, and make interesting images on top of the first.
Here is something else you could do with a scanner and software. Using the edit feature you can enlarge your projects in on the computer screen and then print out only that part. This allows you to make a full sized pattern of anything you wish, turn around and use it to trace the object on plywood. Once you are done, cut out life size reindeer, cows, antique cars, you name it.
Copying Documents - You can turn a good flatbed scanner into a copying machine by scanning in those receipts and other important documents and then use your printer to have a copy. The best thing about this is that you could use software to improve the documents, if you need to take out a grease smudge.
Other things a scanner can do is copy a quick recipe out of Grandmas old recipe book, or a page from a magazine that shows the instructions for a new at home project you have been wanting to do. Maybe there are some old documents in the family that you would like to have a copy of for yourself, those can be added to the computer files just as any other document.
Faxing Documents - You can Fax a document that is already in your computer, but if that document on a sheet of paper, you have a problem. A scanner can scan it in, then you can send it out by using the fax driver. When you have long distance relatives, and you find something in a magazines that they need to see, put the magazine in the scanner and then from the computer send them the information.
OCR - Optical Character Recognition (OCR) software is used to convert images to readable text. Once they are converted you can use word processor to make the changes that are required. When working with a group event and they brought you a printed copy you easily change it. OCR software usually comes with the scanner.
