Printer is actually a Hardware (hardware) connected to the computer, which has a function as a tool to menghasilan / display data in the form of print, either in the form of images or writing from computer to paper or the like .. The printer itself is divided into several parts of the tool paper pickers from the trays often called picker triggers. The tray is a place to put paper. There are two types of ink used are liquid ink and powder ink. Of course the ink is not the same Because each has a difference. Powder or laser ink needs warming, while ink or spray ink does not require heating, just a cleaning on the print head. On the back of the printer there are parallel or USB plugs to connect to the computer.
For those of you who do not know the origin of the printer, this time we share a brief article about the history of the printer that started from the 14th century. Here's the explanation.
A Brief History of Printers
The development of printing or printing techniques has been started since the 14th century which started simply in China. At that time the Chinese had succeeded in creating ink and block printing that had a profound effect on writing traditions through the innovations it developed. But the development of print techniques in China like that lost and not as good as the development that occurred in the plains of Europe. This can happen because the Chinese alphabet has thousands of very specific ideograms, which are very difficult and rare for when applied to typewriters at the time. This has resulted in almost no significant change in terms of production efficiency in China as it did in Europe which has a rapid growth.In the early 1950s, in Europe there was a very rapid cultural development that made the need for the production process of fast and cheap writing documents. Johannes Guternberg is a goldsmith and businessman from Germany, who has successfully developed a printing press technology that has transformed revolutionary printing techniques. Printing is also the most important invention of the millennium, although the impact it has on the global economy is not so great. The discovery of this printing press made the Bible the first book mass produced at the time.
In the 1450s a German metal smith called Johannes Gensfleisch zur Laden zum Gutenberg (ca. 1398 - 3 February 1468) had gained notoriety thanks to some of his inventions at that time in the field of printing technology, his contributions included metal letters aloy (type metal) and also oil-based stints, and prints to print letters appropriately.
The printer has several sections and consists of several types.
Parts of the Printer:
Picker as tool takes paper from Tray.
Tray where to put paper.
Toner or ink is a printer tool, used for writing on paper.
Toner and Ink have different systems;
Toner or Laser is a printer that requires heating
Ink or Inkjet is a printer that does not need heating, this tool is just a cleaning on the print-head printer.
Types of Printers
The printer consists of four types. Here's a complete explanation of the types of printers:Dot
1. Matrix Printer
The Dot Matrix printer is a printer that uses ribbons as its printing tool. Because using the ribbon as the source of color, then the colors that can be generated on this printer does not vary. The resulting colors are only black, blue, and red only. And also very rarely can use all three colors at once.
Some of these printers have a speed of 500 cps. Print resolution on this printer is still very low, the printed image will look like the points are interconnected. Although the current printer technology is increasingly berkemnang and sophisticated, dot matrix printer of this type is still produced. Because this printer can still be used to print a copy document, which is used to make receipts, bills, and other financial documents.
Advantages :
Can print on a wide paper size
The cost of printer and ink (Ribbon) is cheap
Can print multiple copies at once
Weaknesses:
The motion is very slow
Dpi and low ppm
The resulting colors do not vary
His voice is noisy while working
2 . Ink Jet Printer - Desk Jet - Buble Jet
Inkjet Printer is a printing tool that already uses ink to print text or images. This type of printer has the ability to print up to a very large paper size, and with excellent quality.
At present Resolution owned inkjet printer can reach the number 5760 × 1440 dpi. This type of printer has been using dor on demand technology, which is how to spray a small dot of ink on paper through a nozzle or a very small pipe hole.
Placement and replenishment of ink on this type of printer can be modified with infusion techniques, jaadi has made it easier for users. The infusion technique is to add a special ink tube to the outside of the printer and to be attached with a small tube to connect to the printer in the printer.
Can print on a wide piece of paper with good quality
Easier to print images and colors
Dpi & ppm is higher
Weakness
Unable to print order
Operational costs are more expensive
The printing time becomes longer
3. Jet Laser Printer
LaserJet is a type of printer that is arguably the best printer in quality compared to the two types of printers on the previous. The tool used to print on this printer is not using ink but using toner powder and printing system is already using infrared.
This printer also offers a very high printing speed. Even machines belonging to the lower class of this class of lasers still have a high speed compared to Ink Jet printers or Dot Matrix.
Advantages :
Dpi, ppm is very high
Efficient for black and white printing
Has more color capacity
Very fast printing capability
Weaknesses:
High operational costs
Can not be used continuously.
4. Thermal Printer
This thermal printer uses heat to print text or images on paper, not by using ink cartridges like those commonly used by other types of printers. With this technology, making the printer noisy even there are some types of yag does not make a sound at all.
This printer can print very quickly because it does not use pins like the one on the dot matrix printer. Surely this printer has a much more expensive price than the previous one.
