    HP LaserJet 5 printer Game Boy Pocket Printer, a thermal printer released as a peripheral for the Nintendo Game Boy This is an example of a wide-carriage dot matrix printer, designed for wide paper, shown with legal paper. Wide carriage printers were often used in the field of businesses, to print accounting records on tractor-feed paper. They were also called "132-column printers". inkjet printer while printing a page. In computing, a printer is a peripheral device which makes a persistent human-readable representation of graphics or text on paper. The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000. The first electronic printer was the EP-101, invented by Japanese company Epson and released in 1968. The first commercial printers generally used mechanisms from electric typewriters and Teletype machines. The demand for higher speed led to the development of new systems specifically for computer use.

  • Kodak Picture Kiosk


    Kodak Picture Kiosk (previously known as Kodak Picture Maker) is a line of self service photo printing kiosks manufactured by the Eastman Kodak company. ImageWorks|thumb|right|200px The units typically consist of an order station connected to one or more dye-sublimation printer(s) in a single unit. These stations are typically installed in a retail location such as Kodak Express stores, supermarkets and drugstores offering both instant print and behind the counter services. The kiosks allow printing digital photos from digital media (such as a CD or a digital memory card), as well as the ability to scan existing photos and perform simple edits and photo-enhancements via the touch screen interface. Some systems are set up as "order stations" that print to a digital minilab in addition to (or instead of) printing the pictures instantly. The first Kiosk, named the Kodak Picture Maker was introduced in the late 1990s, followed by second, third (G3) and fourth generation (G4) picture kiosks. The most recent model is the Kodak Picture Kiosk G4XE, introduced in 2009.

  • Laser printing


    HP LaserJet 4200 series printer, installed atop high-capacity paper feeder Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated in order to permanently fuse the text, imagery, or both. As with digital photocopiers, laser printers employ a xerographic printing process. However, laser printing differs from analog photocopiers in that the image is produced by the direct scanning of the medium across the printer's photoreceptor. This enables laser printing to copy images more quickly than most photocopiers. Invented at Xerox PARC in the 1970s, laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, quality and speed have increased as price has fallen, and the once cutting-edge printing devices are now ubiquitous.
