Printer and Printing Technology Technology

Printer and Printing Technology Technology

The printer is a hardware output device (hardware) that prints text or illustrations on paper adan other print media are possible. Currently there are different kinds of printers.
Based on the technology used, the printer can fall into the following:
1. Daisy-wheel: Similar to a typewriter that save a plastic or metal (such as hammer), which is printed every letter that will print the letter by pressing a ribbon. Ink-jet printers can print only letters and no graphics.
2. Dot-matrix: Creates characters by striking pins against an ink ribbon. Each pin makes a dot, and combinations of dots form characters and illustrations.
3. Ink-jet: Sprays ink on a sheet of paper. Ink-jet printers can produce text and graphics with high quality.
4. Laser: This printer uses the same technology as copy machines. These printers can produce text and graphics with a very high quality.
5. LCD & LED: This printer is similar to a laser printer, but uses liquid crystals (liquid crystals) or light emitting diodes (light-emitting diodes).
6. Line printer: Contains a chain of characters or pins that print an entire line at a time. This printer is very fast but with low quality.
7. Thermal printers: These printers use heated pins which are pressed with heat sensitive paper. These printers are widely used in calculators and fax machines.
The printer can also be classified based on the following characteristics.
1. The quality of mold or mold that is the output generated by the printer.
2. Print speed is measured in characters per second, or pages per minute.
3. Impact or non-impact related to the working system printers. Printer technology with a daisy-wheel, dot-matrix, and line printers are impact printers, but printers with laser technology and ink-jet is non-impact printers. The second important difference is the type of printer kegaduhannya. Impact printer is more noisy than the non-impact printers.
4. Print capabilities associated with text and graphics. Some printers can print only text and others can print text and graphics.
5. Font or typeface that can be printed. For example, dot-matrix printers can print only a few fonts. In contrast, laser printers and ink-jet printers capable of printing fonts are almost unlimited.


. History of Printers and Printing Technology
Printing technique has been implemented in a simple print in China in the 14th century. Innovation Chinese people have succeeded in creating and block printing inks which have great impact on the tradition of writing. But the development of printing techniques in China is not as good as with the developments taking place in Europe. This occurs because the Chinese alphabet has thousands of ideograms 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 1950s, the cultural development occurred very rapidly in Europe that raises the need for paper document production process is quick and cheap. Johannes is Guternberg, a goldsmith and businessman from Germany, which succeeded in developing printing technology that has changed in a revolutionary printing techniques. Printing itself is probably the most important discoveries in the last millennium, although its impact on the global economy is not too large. This allows the invention of printing the Bible to be the first book produced in bulk.
History of Inkjet Printers
Inkjet printer system introduced in tahun1984. with inkjet printers and printer ink cartridges, the task of printing the document and replacement ink cartridges more often used, more reliable with results that are cleaner than on tape or charging the toner cartridge.
In 1984, the acceptance of this system has not become dependent as it is today. Inkjet printers replacing dot matrix printer system, which resulted in the replacement ribbon. Shortly thereafter, the factories began to conceptualize the technology of inkjet printers, according to the demands of progress. Some companies are starting to control the progress of inkjet behind. And in the 90's, these methods are widespread. Current methods of cartridges needed to print both black and white or color images and photos. Development of the ink cartridges should be proud of, because of its ability to produce prints on paper of different types and sizes, factory, film and others. These printers are also used for schools, homes and millions of people around the world.
History of Laser Printers
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 discovery of laser printer technology. Laser printer called EARS actually developed at the Xerox Palo Alto Research Center, at the beginning of 1969 and completed in November 1971. Xerox experts, Gary Starkweather Xerox copy of adopting the technology into a laser printer. Xerox 9700 is the first Xerox laser printer products with laser xerographic technology in realase 1977. IBM's own launch this technology with the IBM 3800 is installed first 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. Combines laser technology and electrophotography. In 1992, Hewlett-Packard introduced the famous LaseJet 4, using a resolution of 600 x 600 dot per inch (dpi).
Printer Types
The printer type is distinguished by:
1. Print resolution
2. Speed
3. Printer media
4. Engineering Print
5. Connection type
6. Print media
Print resolution
Understanding the resolution of the printer is the printer's capabilities in creating a number of points in one square inch. For example, a resolution of 720x 720 dpi (dot per inch) means that the printer can make 720 dots per 1 inch vertical and 720 horizontal dots per 1 inch
Information on the print resolution in a printer is usually given in the manual book or a patch on a sticker on the back of a printer.
Speed
Printer speed is expressed in PPM (pages per minute). The faster and sharper view of the output, price and even then the more expensive printers. (Ditto)
Depends on the speed of a printer memory contained in the mainboard and media types pencetaknya.
Printer Media
- Ribbon
Tape used as media to the printer dot matrix printer. The printer of this type usually use the head with a system of work shed needles in accordance with the view to be printed. Head of this type is called dot matrix, because the needles that form a matrix of dots to be printed following the results. Head composed of 9 pin and 24 pin. Pin is available in the needle head. The more needles that exist (24 pin), the better the print.
Including this type of printer like the Epson LX-800, Epson LQ 2170, etc..
- Ink
Ink-jet printers use ink as a medium pencetaknya. Head that is used is the type of head that regulates the release of ink according to the printout. Head of this type usually called cartridges.
Including this type of printer is an inkjet printer, deskjet (HP) and bublejet (Canon Products).
- Toner
Ink-jet printers use toner as print media. Toner is a powder that is used as a printer by way of the "sprinkle" in the print media (like paper) in accordance with the results to be printed, then heated using light. The principle of such work is also done by a photo copy machine.
Including this type of printer is the HP LaserJet 6L printer, etc..
Engineering Print
Based on printing techniques, there are two kinds of printers are impact and non impact. Impact is a printer that does printing techniques by tapping (hitting) the needle head to the ribbon, while the non-impact printer is done printing techniques by way of spraying, including this type of inkjet printers and toner.
This type of connectivity
This type of printer connectivity consists of:
1. Parallel Port
Parallel port is a type of connectivity of the initial / first provided by the computer to connect to the printer. Parallel port consists of a port that has a 25 pin (DB25). Each pin has a different function. Among them there is a voltage, ground, output data and input data.
Including the type of printer this is the old generation printers and dot matrix.
2. USB Port
USB or Universal Serial Bus is a type of port used for various purposes, in accordance with its name. With USB, a printer connection can be done with better speed. The disadvantage, with this connection, connectivity can be done only when the operating system has been running, not biased to do in MS-DOS, because the USB port in detection bias in the new operating system like Windows.
3. Other
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. Such 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 will be used in printing technology.
Print Media
Based on Type of Print Media
- Paper
Paper is commonly used print media is paper. Paper used for virtually all printing needs theses, papers and office work.
Almost all types of printer paper as a condition the print media.
- Photo paper
Development of technology, demanding developments in printing technology for residential use. With photo printing technology, we do not bother to do a print from a mobile phone or digital photo. Several types of printers latest release almost all of the features include photo printing. We live to buy photo paper, then we can do photo printing at home.
For better results, a photo printing, usually using 5 pieces of ink, namely, Black, Cyan, Magenta, Light Cyan and Light Magenta.
- Fabrics & Media outer space
This technology is known as digital printing. Typically used by advertising companies or advertising as a medium of outer space, including 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 paper with the size of the folio, A4, and the most used are double folio or A3.
- Plotter
Plotter is a printer capable of printing with a large size, usually biased prints up to A0 width with a length much greater. Plotters are often used for the manufacture of banners and outer space media (billboards).
Plotter according to the dictionary devinisi IT (Ilmukomputer.com, IT Dictionary, Abu Sahl) are: drawing graphics printer using ink pens, plotter is also the first output device capable of printing images for image-sized architectural and engineering drawings.
Plotters are usually also joined its function as a cutting, ie cutting the paper, especially for cutting stickers, etc..
