History of Computer Printers

What is a Computer Printer?
Printer is a tool that displays data in the form of mold, both as text and pictures / graphics, on paper. Printers are usually divided into several parts, the picker as tools take the paper from the tray. Tray is the place to put the paper. Ink or toner printer is a real tool, because there is something called ink or toner used for writing / printing on paper. Differences are differences toner and ink system; toner or laser heating needs, while the inkjet ink or do not need heating, cleaning or just cleaning the print-head printer.

Computer Printer function
Printer is one of the hardware connected to the computer and has the function to print text, images and other display media from computer to paper or similar. The term is known in the resolution of the printer is called dpi (dots per inch). The point is the large number of points in an area of ​​1 inch. The higher the resolution the better the print will be generated. Conversely, if the resolution is lower then the printout will be bad / not good.

History of Computer Printers
Printing technique has been implemented in a simple printing in China in the 14th century. Innovation of Chinese people have succeeded in creating and block printing ink which greatly affect the written tradition. But the development of printing techniques in China are not as good as with the developments taking place in Europe. This happens due to Chinese alphabet has thousands of specific ideograms, which is very difficult if applied at the typewriter. As a result, almost no significant change in terms of production efficiency in China as in Europe.

In the early 1950s, there was a very rapid cultural developments in Europe which raises the need for paper documents the production process faster and cheaper. Johannes is Guternberg, a goldsmith and businessman from Germany, which has developed technology that has changed the printing machine is a revolutionary printing techniques. Printing itself is perhaps the most important invention of the last millennium, although their impact on the global economy is not too big. Invention of the printing press allowed the Bible is the first book to be mass-produced.

History of Inkjet Printer

Inkjet printers are devices that print has been using ink to print and print quality for color images is quite good. Speed ​​print the amount of pages for inkjet printer is not the same, depending on the type of printer brands. But on an inkjet printer, prints dry longer than the laser printer.

Inkjet printer system introduced in tahun1984. with inkjet printers and printer ink cartridges, document printing tasks and replacement ink cartridges more frequently used, the more reliable the results are cleaner than on tape or charging the toner cartridge.

In 1984, revenue is not a dependency system as it is today. Inkjet printer system replaces the dot matrix printer, which resulted in the replacement of the ribbon. Shortly thereafter, the factories began to conceptualize printer inkjet technology, in accordance with the demands of progress. Some companies began to control the progress of inkjet behind. And in the 90s, such methods are widespread. Current methods cartridges needed to print both black and white or color images and pictures. Development of the ink cartridge to be proud, because of its ability to produce prints on different paper types and sizes, factory, films and others. This printer is also used for schools, homes and millions of people around the world.

History of Laser Printers

The majority of shape similar to a laser printer copier. Print is also quite a lot of power can reach more than 10 pieces per minute. Laser printer output quality is very good, so similar to the original. Additionally prints dry quickly. But the price of this printer is quite expensive.

In 1953, high-speed printer was first developed by Remington-Rand UNIVAC computer used. In 1938, Chester Carlson introduced the wet printing process called electrophotography was later named Xerox, which later evolved into the invention of the laser printer technology. Actual laser printer called EARS was developed at the Xerox Palo Alto Research Center, at the start of 1969 and was completed in November 1971. Xerox experts, Gary Starkweather adopt technology into laser printers Xerox copy. Xerox 9700 laser printer is the first Xerox products with laser xerographic technology in realase 1977. IBM itself started with the IBM 3800 technology is first mounted on the central accounting office in FWWoolworth's North American Data Center in Milwaukee, Wisconsin in 1976. IBM 3800 is the industry's first high-speed printer system. Combine laser technology and electrophotography. In 1992, Hewlett-Packard introduced the famous LaseJet 4, using a resolution of 600 x 600 dots per inch (dpi).

Types of Printer

Printer distinguished by its type:

- Print resolution

Understanding the resolution of the printer is the printer's ability to create a number of dots in a square inch. For example, a resolution of 720x 720 dpi (dot per inch) means that the printer can make 720 points per 1 inch vertical and 720 horizontal dots per 1 inch

Details on the print resolution in a printer is usually given in the manual book or patch on a sticker on the back of the printer.

- Speed

Printer speed expressed in PPM (pages per minute). The faster and sharper the resulting display, printer and even then the more expensive price. (Ditto)

Speed ​​of a printer depends on the memory contained in the mainboard and mint media types.

Media Printer

- Ribbon

Printer ribbon is used as a medium in the dot matrix printer. These printers usually use the head with the system work shed needles in accordance with the view to be printed. Head is called the dot matrix type, because the needle shape in the form of dot matrix following the results to be printed. Head consists of 9 pin and 24 pin. The pin is available in a needle head. The more needles there (24 pin) getting better print results.

Including these types of printers like the Epson LX-800, Epson LQ 2170, etc..

- Ink

This type of printer uses ink as a medium mint. Head used is a type of head that regulate the release of ink according to the printout. Head types are usually called cartridges.

Including these types of printers are inkjet printers, deskjet (HP) and bublejet (Canon Products).

- Toner

This type of printer uses toner as the print media. Toner is a powder used as a printer by means of "sprinkle" in the print media (such as paper) in accordance with the results to be printed, and then heated using light. The principle of this kind of work is also done by a photo copy machine.

Including this type of printer is the HP Laserjet 6L Printer, etc..

Print Technique

Based printing techniques, there are two kinds of printers are impact and non-impact. Impact is a printer that performs printing technique by hitting (hitting) the needle head to tape, while the non impact printer is done printing technique by spraying, including this type of printer inkjet and toner cartridges.

Connectivity Type

Type of printer connectivity consists of:

Parallel Port

Parallel port connectivity is kind of the beginning / first provided by the computer to connect to the printer. Parallel port consists of a port that has a 25 pin (DB25). Each of the pins have different functions. Some of which have voltage, ground, input data and output data.

Including this type of printer is the old generation printers and dot matrix.

2. USB Port

USB or Universal Serial Bus is a type of port that is used for various purposes, as the name suggests. With USB, the printer connection can be done with better speed. Weakness, with this connection, connectivity can only be done when the operating system has been running, not bias carried in the MS-DOS, because the USB port on the new bias in the detection of the operating system such as Windows.

3. Others

Printing technology, as well as other technologies, run in accordance with the changing times. Various forms of connectivity is done, not only for the printer, but also other peripherals, such as mobile phones. And infrared connectivity as with many bloothoot be selected. So it's not impossible, if the current printer technology often use parallel and USB ports as connectivity, a time much better connectivity will be used in printing technology.

Print Media

By Media Type Print

- Paper

Paper is commonly used print media is paper. Paper used almost for all the printing needs of theses, papers and office work.

Almost all types of printer paper as a condition the print media.

- Photo paper

Development of technology, demand developments in printing technology for residential use. With photo printing technology, we do not bother to print from a mobile phone or digital photo. Several types of printers include the latest release of almost all the photo printing features. We live buy photo paper, then we can do photo printing at home.

For better results, a photo printing, typically using 5 pieces of ink, ie, Black, Cyan, Magenta, Light Cyan, and Light Magenta.

- Fabrics & Media Outdoor areas

This technology is known as digital printing. Typically used by advertising companies or advertising as a medium of outer space, including the use of banners, billboards, etc..

Based on the size of the print media

- Printer

Printers that we mean here is we use a common printer and also used in offices and schools. Printers generally use legal-sized paper, A4, and most of which are used are double folio or A3.

- Plotter

Plotter is a printer capable of printing at large sizes, usually biased prints up to A0 size wide with a length much greater. Plotter is often used for the manufacture of banners and media outdoor space (billboards).

Plotter according to IT Dictionary is: draw graphics printer using ink pens, plotter output is also the first device capable of printing images sized images for architectural and engineering drawings.

Plotter usually also joined as a function of cutting, ie cutting the paper, especially for cutting stickers, etc..
