A printer is a peripheral which makes a persistent human readable representation of graphics or text on paper or similar physical media. Traditional printers are being used more for special purposes, like printing photographs or artwork, and are no longer a must-have peripheral; 3D printing has become an area of intense interest, allowing the creation of physical objects. An image scanner is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image. Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications.
