Electrostatic Printer ।। Printer is a peripheral device

Download to read offline

Printers are one of the most used peripherals on computers and are commonly used to print text, images, and photos. Some printers can print documents stored on memory cards or from digital cameras and scanners.
A printer is a peripheral device which makes a representation of an electronic document on physical media. It is an external hardware device which is responsible for taking computer data and generating a hard copy of that data.
Electrostatic printer - a printer that uses an electric charge to deposit toner on paper Example:
(1)ink cartridge - a cartridge that contains ink and can be replaced. (2)Laser printer - electrostatic printer that focuses a laser beam to form images that are transferred to paper electrostatically

  3. 3. Introduction Printers are one of the most used peripherals on computers and are commonly used to print text, images, and photos. Some printers can print documents stored on memory cards or from digital cameras and scanners. A printer is a peripheral device which makes a representation of an electronic document on physical media. It is an external hardware device which is responsible for taking computer data and generating a hard copy of that data. Page: 03
  4. 4. What printers should I look at? 1. Home use 2. Professional Use / Small Office 3. Business use Four printer qualities of most interest: 1. Color 2. Regulation 3. Speed 4. Memory Page: 04
  5. 5. Definition of Electrostatic Printer Electrostatic printer - a printer that uses an electric charge to deposit toner on paper Example: (1)ink cartridge - a cartridge that contains ink and can be replaced. (2)Laser printer - electrostatic printer that focuses a laser beam to form images that are transferred to paper electrostatically Figure: Electrostatic printer Page: 05

  7. 7. Electrostatic Printer Methods Page: 07 The electrostatic printing process is one of the most important non impact printing methods because of its versatility and the possibility of high resolution at high printing speeds. The dielectric coated paper (DEC-paper) necessary for this process looks like plain paper and is not expensive. The principle of an electrostatic printer is shown in the first figure. The DEC-paper has to pass two or three stages, the first being the charging process by an electrode system, which generates a gas discharge from selected electrodes. In a second step the latent charge image has to be made visible by a dry or wet developing process, where fine toner particles are forced to adhere to the charged areas. The final step serves to fix the toner image, e.g. by melting of dry toner particles by application of heat.
  8. 8. Electrostatic Printing Process Page: 08 Electrostatic printing is a printing technique done without any plate, ink or type form. The paper is coated with a thin layer of zinc oxide, making it an insulator in the dark and simultaneously a conductor of electricity when exposed to light. These machines are used for printing of geographic maps. With the advancement in technology and higher speed, the machines are also being used to print small books. Electrostatic printers are used for short run printing as they are faster and also do not cost much. Figure: Electrostatic printer
  9. 9. Electrostatic Printing Process Page: 09 Electrostatic printing use a positively charged toner/inks that is attracted to paper which in turn is negatively charged. The paper is moved through a digital ink bath; positively charged particles in ink stick to the negative charge on the paper. The printers print in black and white or color as the case may be, and some handle paper up to six feet wide.
  10. 10. Electrostatic Printing Process Page: 10 Application of Electrostatic Printing: Electrostatic printers are widely used in different industries for short run printing. They are popular for photocopying jobs both black & white and colored. These printers are faster than inkjet printers
  11. 11. Advantages Electrostatic Printer Page: 11 Reliable Lowest-cost price per page Ability to print multi-page documents Print up to 5000 lines per minute
  12. 12. Disadvantages Electrostatic Printer Page: 12 Create noise when the pins or typeface strike the ribbon to the paper. Doing it manually is time consuming. Their color performance is low. Their speeds are limited by waiting for the next input.
  13. 13. Conclusion Page: 13 Printers are very important hardware devices used to output information on papers. The study or knowledge of the various types is very essential so as to select the best or most suitable one at a particular point of need or for a particular purpose.
