printer history

What is a Computer Printer?
Printer or printer is a tool that displays the data in printed form, either text or images / graphics, on paper. Printers are usually divided into several parts, the picker as a pick up paper from the tray. Is a place to put the paper tray. Ink or toner printer is a tool actually, because there is something called ink or toner used for writing / printing on paper. The difference is the difference in toner and ink system; toner or laser heating needs, while inkjet ink or do not need heating, just cleaning or cleaning the print-head printer.

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

History of Computer Printers
Printing techniques have been implemented in a simple print in China in the 14th century. Innovation of Chinese people have succeeded in creating and block printing ink that will greatly affect the tradition of writing. But the development of printing techniques in China is not as great as with developments in Europe. This happens because China has thousands of ideograms alphabet specific, 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 1950's, 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 probably the most important discoveries in the last millennium, although their impact on the global economy is not too great. The invention allows the printing of the first book Bible be mass-produced.

History of Inkjet Printer

Inkjet printer is a device that already prints using ink to print and print quality for color images is pretty good. Printing speed inkjet printer page count is not the same, depending on the type of printer brands. But the inkjet printer, the print is dry longer when compared to laser printers.

Inkjet printer system introduced in tahun1984. with inkjet printers and printer ink cartridges, document printing job and replacement ink cartridges more frequently used, the more reliable the results cleaner than a ribbon or toner cartridge filling.

In 1984, revenue is not a dependency system as it is today. Replacing inkjet printer dot matrix printer system, 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 90's, such methods are widespread. Currently cartridge method is needed to print both black and white or color images and pictures. Developments ink cartridge proud of, because of its ability to produce prints on paper of different types and sizes, factory, film and others. This printer is also used for schools, homes, and millions of people around the world.

History of Laser Printers

Some of the laser printer looks like a copier. Power print is also pretty much could reach more than 10 pieces per minute. Print quality is very good laser printer, so similar to the original. Besides prints dry quickly. But the price of this printer is quite expensive.

In 1953, high-speed printer was first developed by Remington-Rand UNIVAC used on the computer. In 1938, Chester Carlson introduced a printing process called electrophotography wet was later named Xerox, which later developed into the discovery of laser printer technology. The laser printer called EARS actually developed at Xerox Palo Alto Research Center, started in 1969 and completed in November 1971. Xerox experts, Gary Starkweather Xerox copy adopting a laser printer. Xerox 9700 is the first product Xerox laser printer with laser xerographic technology in realase 1977. IBM itself started with IBM technology was first installed in 3800 the headquarters accounting 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 species distinguished by:

- 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 a patch on a sticker on the back of the printer.

- Speed

Printer speed expressed in PPM (pages per minute). The faster and sharper display is produced, prices rose more expensive printers. (Ditto)

Speed ​​of a printer depends on the memory available in the mainboard and pencetaknya media types.

Media Printer

- Ribbon

The tape is used as a medium for the printer dot matrix printer. Ink-jet printers typically use the head with the system work shed needles in accordance with the view to be printed. Head type is called dot matrix, because the matrix needle shape in the form of a point following the results to be printed. Head consists of 9 pin and 24 pin. Pin is available in the needle head. The more needles there (24 pin) is getting good prints.

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

- Ink

Ink-jet printers use ink as a medium pencetaknya. Head is the type of head used discharge ink set according to the results of the mold. Head of this type usually called cartridges.

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

- Toner

This type of printer uses toner as print media. Toner is a powder used as a printer by way of the "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..

Technique Print

Based on printing techniques, there are two kinds of printers are impact and non-impact. Impact printer is printing techniques by tapping (hitting) the needle head to the tape, while the non impact printer is printing techniques by way of spraying, including this type is an inkjet printer and toner.

Type of connectivity

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 ports consist of ports that have a 25 pin (DB25). Each pin has a different function. 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 the type of port that is used for various purposes, as the name suggests. With USB, the printer connection can be done with better speed. The disadvantage with this connection, connectivity can only be done when the operating system is running, not biased done in MS-DOS, for a new USB port bias on the detection in the operating system such as Windows.

3. Other

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

Print Media

By Type Print Media

- Paper

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

Almost all types of printer paper condition as print media.

- Photo paper

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

For better results, a photo printing, inks typically use 5 pieces, namely, Black, Cyan, Magenta, Light Cyan, Magenta and light.

- Fabrics & Media outdoor space

This technology is known as digital printing. Usually used by advertising companies or advertising as a medium outer space, including the use for 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. Generally, the printer uses folio-size paper, A4, and the most used is double folio or A3.

- Plotter

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

Plotter in TI dictionary devinisi (Ilmukomputer.com, IT Dictionary, Abu Sahl) are: drawing 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 its function as a cutting, the cutting of paper, especially for cutting stickers, etc..
