As a kind of visual artist, the graphic designer usually works from a relatively technical standpoint. Unlike visual artists who sell expressive art works to private buyers, a graphic designer will sell visuals that work in a commercial or other presentation context, often using a combination of drawn or painted and computer-generated visuals. A graphic designer may work for a larger graphic design firm, or he or she may freelance as an independent contractor for multiple clients. Graphic design services are valuable to any business or organization using visuals in any medium, from print to Internet, television or other new media.
An image scanner is a digital device used to scan images, pictures, printed text and objects and then convert them to digital images. Image scanners are used in a variety of domestic and industrial applications like design, reverse engineering, orthotics, gaming and testing. The most widely used type of scanner in offices or homes is a flatbed scanner, also known as a Xerox machine. This modern image scanner is a descendant of early fax input devices and telegraphy equipment.
The image scanner was
introduced in 1957 by a team led by Russell Kirsch at the U.S. National Bureau

based on the array characteristics. Image resolution is measured in pixels per
inch.
There are various types of scanners:
