What are the Different Types of Modern Printers?

A printer is a device designed to print information from a computer to paper. They differ by the principle of operation, the number of colors, the type of ink, and the printed material. And each of these types has its own characteristics and additional functions.

Matrix printer
The image is created with a printing head consisting of a set of needles (matrix), which are driven by electromagnets. The head moves line by line along the sheet of paper, and the needles strike it through the ink ribbon, leaving an imprint — a dotted image.

However, low quality does not allow using matrix devices in many areas. In addition, these printers have a low printing speed and make much noise.
Although there are some advantages. For example, such a printer can work in almost any conditions and with any paper formats, and prints are not only resistant to friction and moisture, but also significantly complicate the documents forgery.

Inkjet printer
Such printers use a printing head that prints with liquid inks. It can be embedded in a cartridge or fixed in the device itself. Inkjet printers are classified by many features.

By the type of ink used:

  • water;
  • oil;
  • pigmented;
  • solvent;
  • thermotransfer.

By what is used for:

  • office;
  • broadsheet;
  • interior;
  • marking;
  • photo printers;
  • souvenir for printing on small items;
  • manicure.

The printing speed is not very high. In this case, prints are exposed to water, light and mechanical impact. The device will give high-quality images only when you regularly print with all print cartridges. If you do not print for a long, the ink quickly dries.

The main disadvantage is the high maintenance cost. The ink is over very quickly, and the user has to refill them periodically. It costs a lot.

Laser printer
This printing method is characterized by speed, economy and high print quality. The main part of the device is a so-called OPC drum, which keeps an electric charge on the surface, and it differs at each point. The laser beam, getting on the drum, lights up the individual points removing the charge from them. Managing the beam, you can draw on the drum with charged and uncharged areas.

The toner is poured down to the drum and sticks only to charged points, thereby forming an image. The image transfers to the paper under the high temperature and pressure.

This technology provides a very good result: the printing speed is really high. The print quality is also very high. In addition, the print is resistant to friction and moisture.

The plus of a laser printer is its ability to print on virtually any paper without losing the quality. Among the disadvantages — high cost, although it is quite cheap to maintain. Also, it does not always reproduce the color well.

LED printers
Instead of a single laser beam, this type of printers uses a block of LEDs. Each point in the line has its own LED, so the light source does not move, unlike laser technology.

This is the first advantage: fewer mechanics — higher reliability. The second advantage is high speed (from 40 pages per minute). In addition, the print quality is higher than the laser printer, and there are no edge distortions. However, the LED printer has one significant disadvantage — the high cost.

Other types of printers
Sublimation printers — to print pictures, they use a special film. They provide a high quality of photos.
Drum printers are not used anymore. The drum rotated, and when the required symbol moved by the sheet of paper, a special hammer struck the paper, typing a letter or digit through the ink ribbon.

As you can see, there are a lot of various types of printers. They are designed for different needs, and you should think carefully why you need it before buying the device.
