Printer

  1. 1. ANKIT S. CHITNAVIS
  2. 2. Introduction  In 1938, Chester Carlson invented a dry printing process called electrophotography commonly called a Xerox.  In 1953, the first high-speed printer was developed by Remington-Rand for use on the Univac computer.  In 1976, the inkjet printer was invented, but it took until 1988 for the inkjet to become a home consumer item with Hewlett-Parkard's release of the DeskJet inkjet printer, priced at a whopping $1000.  In 1992, Hewlett-Packard released the popular LaserJet 4, the first 600 by 600 dots per inch resolution laser printer.
  3. 3. What is Printer ?  An external hardware device responsible for taking computer data and generating a hard copy of that data.  Printers are one of the most commonly used peripherals and they print text and still images on the paper.
  4. 4. Printer Impact Daisy Wheel Matrix Non-Impact Inkjet Thermal Laser
  5. 5. Impact Printer  These printers have a mechanism that touches the paper to create an image.  printers work by banging a print head containing a number of metal pins which strike an inked ribbon placed between the print head and the paper
  6. 6. An impact printer showing details of print head
  7. 7. Non-Impact Printer  These printers create an image on the print medium without the use of force.  They don’t touch the paper while creating an image.  Non-impact printers are much quieter than impact printers as they don’t strike the paper.
  8. 8. A non-impact printer
  9. 9. Dot Matrix Printer  The term dot matrix refers to the process of placing dots to form an image.  Its speed is usually 30 to 550 characters per second (cps).  This is the cheapest and the most noisy printer and has a low print quality.  Dot Matrix were 1st introduced by Centronics in 1970. The dot matrix forms images one character at a time as the print head moves across the paper. Uses tiny pins to hit an ink ribbon and the paper much as a typewriter does.
  10. 10. “A typical dot matrix output”
  11. 11. Daisy Wheel Printer  A daisy wheel printer is basically an impact printer consisting of a wheel and attached extensions on which molded metal characters are mounted.  A daisy wheel printer produces letter quality print and it can’t produce graphics output.  In a daisy wheel printer, a hammer presses the wheel against a ribbon which in turn makes an ink stain on the paper in the form of a character mounted on the wheel extensions.  Its printing speed is also very slow ,i.e. less than 90cps.
  12. 12. Daisy Wheel Printer
  13. 13. Ink-Jet Printer  It is a non-impact printer producing a high quality print.  A standard Inkjet printer has a resolution of 300dpi.  Inkjet printers were introduced in the later half of 1980s and are very popular owing to their extra-ordinary performance.  Print head having four ink cartridges moves .  Software instructs where to apply dots of ink, which color and what quantity to use.  Electrical pulses are sent to the resistors behind each nozzle.  Vapor bubbles of ink are formed by resistors and the ink is forced to the paper through nozzles.  A matrix of dots forms characters and pictures.

  15. 15. Thermal Printer  Thermal printers are in-expensive printers mostly used in       fax machines. The Thermal printers are further classified into two types. (1) Electro thermal printers: (2) Thermal Wax printers: Thermal printers use heated pins and ribbons with different color bands. These printers contain a stick of wax like ink. The ribbon passes infront of a print head that has a series of tiny heated pins. The pins cause the wax to melt and adhere to the paper and when temperature reaches to a certain level, it is hardened.

  17. 17. Multi-function printer  A multi function printer abbreviated as MFP is an all purpose device that prints, faxes, copies and scans.  A single multi function printer can replace several bulky devices.  A multi function printer is also known as AIO.  These printers use inkjet technology and provide high quality print but at slow speed.
  18. 18. Plotter  A large scale printer which is very accurate in producing engineering drawings and architectural blueprints.  Two types of plotters are flatbed and drum.  Flatbed plotters are horizontally aligned while drum plotters are vertically positioned
  19. 19. LG Pocket Printer  LG introduce new type of printer i.e. LG Pocket Photo. It is one type of printer with a metallic finish on its edges.  Measuring :-4.76-inches tall , 2.83-inches wide, and 0.94- inches thick , the printer is reminiscent of Polaroid’s PoGo Instant Mobile Printer, except in order to transfer photos from a smartphone, it’s also capable of NFC communication in addition to Bluetooth.  To print photos, the device uses Zink, or Zero ink, paper technology.  The printer heats up the dye crystals embedded inside the paper, triggering it to change colors accordingly to the

  21. 21. Planon PrintStik  Planon PrintStik is a small portable printer which prints without ink By Damir Beciri.  The PrintStik is remarkably small, about 2.5 x 5 x 27.5cm (1 x 2 x 11inches), and it has a cartridge with 20 pages of paper inside, making it easy to carry in a coat pocket, laptop bag, or your suitcase or purse.  It is also light and weights just 0.7kg (1.5 pounds). There isn’t much to control on the printer itself.  Buttons on the side are for power on/off and paper feed. Lights indicate if the unit is on, data rate and the battery level.

  23. 23. 3D Printer  3D printing is a process of melting plastic filament and creating solid objects by building them up in very thin layers.  The technology is used in a wide range of industries from construction to aerospace, and is now starting to make its way into the mainstream.
  24. 24. Disadvantage Of 3D Printer  Many of the 3D printers on the market today rely on a process called “heated thermoplastic extrusion and deposition”, which emits ultrafine particles (UFPs) into the air. These particles are less than 100-nanometres in diameter.  In an industrial environment, these particles would normally be removed by a ventilation system, but commercially available printers are currently sold as standalone devices without any exhaust ventilation or filtration accessories.  If these particles are inhaled they can build up in the lungs or be absorbed directly into the bloodstream, potentially resulting in adverse health effects including total and cardio-respiratory mortality, hospital admissions for stroke, and asthma symptoms.
  25. 25. 3D Printer
  26. 26. Conclusion  In fact computer world is incomplete without printers in the modern age of technology.  A printer is one of the basic needs of every computer user and one can not utilize computer resources properly in the absence of a quality printer.
