Printers, Plotters, Cameras, Scanners

Printers, Plotters
The two most common types of printers are Ink-Jet and Laser producing different quality of print and costs.
 * Laser printers work by placing an electronic charge on paper which attracts powered ink called toner which sticks to the paper to produce an image, this uses ink more efficiently and produces a high quality print although it is more costly.

Plotters are another type of printer for printing vector graphics, it uses a pen to draw lines onto paper which allows for continuous lines to be drawn instead of tiny dots. They are typically used in engineering applications as they offer greater precision. In most cases plotters have been replaced by other types of printers.
 * Ink-Jet printers work by spraying tiny amounts of ink onto paper to produce an image, they offer better colour and are cheaper to buy but they are slower and use up more ink.

Digital Cameras
A digital camera stores an image as digital information instead of on film like traditional cameras. They take in the light through the lenses and use digitizing mechanism which converts the light into data that is processed and stored. The quality camera can vary depending on the quality and resolution of the digitizing mechanism used whereas traditional cameras don’t have resolution.

Scanners
Scanners allow a user to place a document in the scanner and it will create a digital image of the document. It digitizes the image placed in the scanner dividing it into a grid of pixels with each pixel having colour data.
