Scanners are relatively inexpensive, yet powerful, imaging devices Perhaps you wonder what’s so great about the capability to scan photos, especially if you can use your office copier for free

be stored and edited on your computer
Why Scanned Images Are Better than Paper Ones
The photos that capture your most precious memories can be made a lot more poignant when you convert them to digital images Business graphics, logos, and visual presentations can work ever so much more effectively if they, too, are captured
