The Types Of Computer Printers

Do you have a printer at home? Or you often work using a printer? But do you know what kind of printer do you use? If you do not know, let me invite you to get to know the types of printers to be known well what the pros and cons. So you can choose the type of printer to suit your needs

The printer is a hardware device that is connected to the computer that is used to produce high mold either writing or pictures from your computer on media paper or the like. There are many kinds of printer types, namely Dot Matrix Printer, Ink jet printers and laser jet printers. Currently, several types of printers are able to print your data contained in Smartphone without having to connect it with a cable (wireless) using wi-fi technology.

At the moment there are 3 types of printers are easy to come across the dot matrix printers, inkjet and laser jet printers. In addition to the two printers under apparently there are many types of printers that have different functions. Here's the explanation of the types of printers that I know of:

This follows a thorough discussion of the types of printers.

Types of Printer
1. Dot Matrix Printer
Dot Metrics kind of printer is the printer printing method using the beat of the needle on the tape. The resulting prints look like the points each connecting to one another, so that the printout is less smooth and less good. By using this printer, can print directly concurrently with carbon. Because its printing systems still use the system beats. Since using the tape as a source of color, the color can be produced was not varied. Only black, blue, and red only. And rarely are able to use these three colors at once. Print resolution is very low, because the printed image will look like dots interconnected. historically this type of printer Dot Matrix 9 Pin initially using the mean in one letter will be printed with a combination of 9 points, then increasingly evolved into a 24-pin and of course with so prints will be much smoother. type of dot metrix printer manufacturers are quite famous is Epson, the Epson LX products Epson LX-300, Epson LX-800 and other.



Dot Matrix Printer How it Works
Dot matrix printer first known in 1964, in 1970, most of the dot matrix printer industry is owned by the company Digital and Centronics, and Centronics prefer the low-end market than Digital. LA30, LA36, and Centronics 101 is a dot matrix printer in the early development of the dot matrix printer. 1970-1990 in dot matrix printers are the most reliable printers in terms of results and cost. In 1990 began to emerge dot matrix printer that supports connection to a computer using a USB port.

Dot-Matrix printers are printers that print is still very low resolution. Additionally, when is printing, the printer of this type tend to be loud and sound quality is not good for printing images because the images are printed to look like the points that are interconnected.

Head of printer's type, consisting of 7 or 9 or 24 needles are arranged in vertical and form a column. When working, the needle will form the character of existing images through friction and needle on carbon paper. This type of printer is also a character printer. Speed ​​varies, but for Epson LX-80, is 80 character per second.

At the time of the head-printer moves from left to right, touching the paper, the letters that have been patterned in an array of needles will soon appear. Letter patterns is then received by a ribbon of carbon paper behind there, and there was a printing letter by letter.

Each character is formed will lead to a unique pattern that consists of various points within the dimensions of a matrix. Types of dot-matrix printers vary greatly, there are manifold color and some are non-color. Generally, dot-matrix printer type also has only one color, which is black. For color printers, used tape (carbon / ribbon) that have a special 4 colors, namely black, blue, red and yellow.
This printer is still widely used because it is well known 'stubborn' (durable). Another plus, dot-matrix printer ribbon is much cheaper than the toner (ink) for inkjet and laser jet printer types.

Function Dot Matrix Printer
Dot matrix printer can be used to print a copy of the document, which is usually used to create receipts, receipts, and other financial documents.

2. Ink Jet Printer
The first printer developed extensively since 1950 and an inkjet printer that can produce images of the new computer was developed in 1970 and controlled by Epson, Hewlett-Packard and Canon.



Ink jet printer type is the type of printer uses liquid ink printing method. printout generated by the type of Ink jet printer is better and smoother than the type of dot matrix printers, ink jet type printers can also produce high color printouts

How it Works Ink Jet Printer
At Ink jet printers use a type of technology dor on demand, ie by spraying tiny dots of ink on paper through a nozzle or a very small hole in the pipe. Other technologies developed by manufacturers such as Canon and HP printer using heat. The heat can make bubbles of ink so if the heat will further depress the nozzle to the specified ink and printed on paper.

Because it uses liquid ink prints to wait a few seconds in order to dry. This type of ink jet printer ink placement and replenishment can be modified by the infusion technique, ie by adding a special ink tubes on the outside of the printer and connected with a small hose to be connected on the printer in the printer engine.

Function Inkjet Printer
Inkjet printers have the ability to print up very large paper sizes, and with excellent quality are commonly used to print images, papers etc..

3. Laser Jet Printer
The first laser printer invented by Gary Starkweather at Xerox in 1969. LaserJet printer is a kind of most excellent quality in the appeal before the two types of printers. Print tool does not use ink but instead uses powdered toner and printing using infra red.



This printer also offers high-speed printing. Even machines that belong to lower class of lasers even this group still has a high speed compared to the Ink Jet printer or Dot Matrix. At least two times faster than inkjet printers. Working similar to a laser printer copier, which uses photographic drum. Quality of the prints produced both fast and sharp. Laser printer is ideal to use for those who print very high frequency. Usually the office is office. However, it is also the user's home using a laser printer. It's just for color laser printers are similar to inkjet quality, the price can be two times larger than the inkjet printer itself.
How it Works Laser Jet Printer

Principle used in laser printers is static electrical principles, beginning is the photoreceptor drum (OPC Drum) was given a positive charge by the Primary Charging Roller (PCR), to provide electrical current to it.

Then shining a laser printer is very small across the surface of the photoreceptor drum to form a writing or drawing images according to the data sent by the computer, one horizontal line at a time. The laser beam of light on the right highlight the photoreceptor drum to form a point and turn off the light for the space per page. Laser beam does not move by itself but the laser beam was reflected through a mirror that can move on its own. The laser beam is definitely a stop at the point in the photoreceptor drum and electrostatic image forming (that turns the drum surface becomes negatively charged).

Once the pattern is complete image, toner stored in the toner hopper (inside the cartridge) is taken by the Developer Unit (magnetic sleeve). Positively charged toner attached to the photoreceptor drum area who have formed an electrostatic image but not the positively charged areas (areas that are not exposed to the laser beam).

Sheet of paper (with a strong negative charge) move along the belt and above the drum roll that has been spiked with toner powder pattern. Paper pushing the toner powder from the drum to switch attached to the paper so that the pattern image with toner powder and paper ready to move on to finishing the fuser.

Loose toner on paper and still attached to the OPC drum is removed by Wiper Blade and then into the Waste Bin.

4. Printer LED / LCD



Basically the type of printer LED / LCD is almost the same as a laser printer but do not use the laser to create patterns on the drums but using light. People often equate Laser printer with printer LED / LCD. Printing process is almost the same printer but the printer LED / LCD uses light-emitting diodes. This printer produces very high quality prints both text and graphics.

5. Solid Ink Printer



These printers use a type of ink that has been waxing. The way it works is printer wax melt ink is then stored in a place which is then transferred to a type of drum which then will cool the new printing ink to paper. Solid Ink printers. When compared with the kind - other types of printers, types of printers have fewer components in. Temperature and humidity affect the printer's paper.

6. Dye Sublimation Printer



This type of printer is a professional tool that is widely used in the graphic arts and photography for printing on mugs and other objects with a hard surface. These printers work by heating the ink so that the change from solid to gas.

7. Portable printers



Portable printers are usually quite mild and sometimes use batteries. The printer usually has a print resolution suitable for printing plain text. You can find several types of portable printers namely: Thermal Printer, Thermal Transfer Printer and Inkjet Printer. The main advantage of Printer Thermal Transfer and Thermal Printer is smaller and lighter than the Inkjet Printer. Average thermal transfer printers and thermal printers have a weight as heavy as a pound. Inkjet printers are usually more portable weighing 2 kilograms of Thermal Printer. Thermal printers require special paper for printing.

8. Plotter printer



This type of printer is very accurate in the printing process. These printers are large and are usually used to print images arsitrk or engineer. There are 2 types of the flatbed plotter printer plotter and drum plotter.

9. Digital Photo Printers



Although most types of inkjet and laserjet printers are able to print photos, photographer still want a printer with a higher print results. Usually there are some extra ink light cyan and the light magenta.

10. Printer CD/DVD



This printer works by printing the cover on CD and DVD.

11. ID Card Printer



These printers are usually used to print ID card quickly and in large numbers.

12. Printer POS (Point Of Sale)



This type of printer is very easy to find in a store gauze. This printer is also connected with the existing cash drawers underneath.

13. Label printer



Label printers are used to print a label with a lot of amount and easier. Some Label Printer has many functions at once that the supermarket can also be used to print barcode. Some label printers can also print labels with a variety of forms.
