Содержание слайда: 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.

Содержание слайда: 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.

Содержание 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.

Содержание слайда: 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.

Содержание слайда: 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.
