  1. The Printer Caleb Miller Hour 2 PC Networking

  2. The General History of the Printer. • The first printer known to man was invented in China sometime before 220 AD. It was a wood block with etched in images that was dipped in ink and pressed onto a piece of fabric. • In 1454 the printing press was invented. • In 1847 the rotary printing press was invented by Richard March Hoe. • In 1876 the mimeograph was invented. Printing Press This is a Mimeograph

  3. The General History of the Printer. • In 1938 Chester Carlson invented a printing process called electrophotography it is known to us as a Xerox • In 1953 the first high speed printer was produced by Remington-Rand for the Univac computer. • The first laser printer was developed in 1971. It was called EARS. It was developed by Xerox Palo Alto Research Center. • The first IBM 3800 was installed in 1976 at the Central Accounting Office in Milwaukee, Wisconsin. • In 1976 the first Ink-Jet printer was developed. • In 1992, Hewlett-Packard released the popular LaserJet 4, the first 600 by 600 dots per inch resolution laser printer.  This is the LaserJet 4. This is the IBM 3800.

  4. The General History of the Printer. • In 1993 QMS introduces the ColorScript Laser 1000, it was $12,445 new. • In 1995 Apple Computer introduces its first color laser printer. • In 1996 Hewlett-Packard begins shipping the HP LaserJet 5. HP LaserJet 5

  5. Some types of printers are… • Bubble-Jet Printers • Laser Printers • LED/LCD Printers • Impact (Dot-Matrix) Printers • Solid Ink Printers • Dye Sublimation Printers

  6. How bubble-jet printers work. • Bubble-jet printers use ionized drops of ink instead of a laser to print the image. They use magnetized plates to direct the inks path on the paper to form letters and images. Almost all bubble-jets come with the color printing option as a standard setting. Bubble-jet printers are capable of creating an image that is similar in quality to a laser printer’s picture quality. A standard bubble-jet printer has a resolution of 300 ink dots per inch, although newer models have improved resolution.

  7. How laser printers work. • Laser printers operate by shining a laser onto a drum. The drum rolls through a pool of electrically charged ink. Using heat and pressure the ink is transferred from the drum to the piece of paper. Color laser printers use the same printing process as a black and white laser printer except they combine four different toner colors. Color laser printers can be used as black and white printers as well. Laser printers print very fast and the ink cartridges last a relatively long period of time.

  8. How LED/LCD printers work. • They are electro photographic printers that are basically identical to laser printers. Both LCD (liquid crystal display) and LED (light-emitting diode) printers us a light rather than a laser to create an image on a drum. They use the LED lights to charge the drum and LCD printers use liquid crystals. These printers produce high quality graphics and images. This is the difference between a laser printer and an LED printer.

  9. How impact (dot-matirx) printers work. • These printers use a set of closely spaced pins and a ribbon to print letters or other characters onto the page. These printers actually hit the page as an old fashioned typewriter would. Impact printers can vary in printing speed from anywhere from around 50 CPS (characters per second) to 500 CPS. They also vary in the number of pins which could effect the speed of the printer. Most impact printers use from around 9 to 24 pins. Those numbers can vary the quality of the printing job. They are mostly used to print invoices, purchase orders, shipping forms, labels and other multi-part forms.

  10. How solid ink printers work. • These printers use solid wax ink stacks in a phase change process. They liquefy the wax sticks and drain the fluid into a reservoir. It then squirts the liquid wax ink onto a transfer drum. It is then cold fused onto the paper in a single pass. These printers offer better color consistency and they are more reliable because there are less inside components as opposed to a laser printer.

  11. How dye sublimation printers work. • Dye Sublimation Printers are professional devices more used for extremely detailed graphics and images. These printers heat up the solid ink and form it into a gas. The heating temperature in the printer can be changed so you can alter the detail and quality of the image. This means that color is applied as a continuous tone rather than in dots as in an Ink-Jet. One color is laid over the entire sheet at a time starting with yellow and ending with black. These printers require a highly priced paper material. The ink is on large rolls of film which contains each color.

  12. Some Printer Manufactures • Apple, Canon, Hitachi, Fujifilm, Epson, Fujitsu, HP, Mitsubishi, IBM, Kodak, Panasonic, Samsung, Sharp and Toshiba.
