WHAT IS PRINTER? A printer is an output device that produces text and graphics on paper. Many printers are primarily used as local peripherals, and are attached by a printer cable or, in most newer printers, a USB cable to a computer which serves as a document source. In addition, a few modern printers can directly interface to electronic media such as memory card, or to image capture devices such as digital camera.

TYPE OF PRINTER Printers can be divided into two main groups, impact printer and non-impact printer. Impact printer produces text and images when tiny wire pins on print head strike the ink ribbon by physically contacting the paper. Non-impact printer produces text and graphics on paper without actually striking the paper. Printers can also be categorized based on the print method or print technology.

Описание слайда:

DOT MATRIX PRINTER The term dot matrix printer is specifically used for impact printers that use a matrix of small pins to create precise dots Each dot is produced by a tiny metal rod, also called a "wire" or "pin", which is driven forward by the power of a tiny electromagnet, either directly or through small levers. Such printers would have either 7 or 9 or 18 or 24 pins on the print head. 24-pin print heads were able to print at a higher quality.

INKJET PRINTER An inkjet printer is a type of computer printer that reproduces a digital image by propelling variably-sized droplets of liquid material (ink) onto a page. Desktop inkjet printers, as used in offices or at home, tend to use aqueous inks based on a mixture of water, glycol and dyes or pigments. A typical ink-jet printer provides a resolution of 300 dots per inch, although some newer models offer higher resolutions.

LASER PRINTER Laser printers are non-impact printers which can print text and images in high speed and high quality resolution, ranging from 600 to 1200 dpi. A laser beam projects an image of the page to be printed onto an electrically charged rotating drum coated with selenium. Laser printers produce very high-quality print and are capable of printing an almost unlimited variety of fonts.
