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.
In the 1980s were daisy wheel systems similar to typewriters, line printers that produced similar output but at much higher speed, and dot matrix systems that could mix text and graphics but produced relatively low-quality output.
Solid ink printers, also known as phase-change printers, are a type of thermal transfer printer.
The paper then passes over the print drum, at which time the image is immediately transferred, or transfixed, to the page.Solid ink printers are most commonly used as colour office printers, and are excellent at printing on transparencies and other non-porous media.
Drawbacks of the technology include high energy consumption and long warm-up times from a cold state.Also, some users complain that the resulting prints are difficult to write on, as the wax tends to repel inks from pens, and are difficult to feed through automatic document feeders, but these traits have been significantly reduced in later models.
In addition, this type of printer is only available from one manufacturer, Xerox, manufactured as part of their Xerox Phaser office printer line.
Laser printing is an electrostatic digital printing process.
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.Źródło: https://en.wikipedia.org/wiki/Laser_printing.
