Слайд 2: 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.

Слайд 3: 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.

The most popular ones are : inkjet printer laser printer dot-matrix printer thermal printer Among these, only dot-matrix printer is impact printer and the others are non-impact printers.

Слайд 5: 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.

Слайд 9: 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.

Слайд 11: 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.

Слайд 16: OTHER TYPE OF PRINTER

Thermal printers The heat activates the thermo-sensitive coloring ayer of the thermo-sensitive paper, which manifests a pattern of color change in response Photo printers Are color printers that produce photo lab quality pictures on photo paper. All in one printers It is a machine that includes several functionalities including printer, scanner, copier and fax. Color printer Its new generation color printers which works on the principal of ink-jet printers. Dye sublimation printer Which employs a printing process that uses heat to transfer dye onto a medium such as a plastic card, paper, or fabric
