Printer selection

In this article we will consider the main types of printers, as well as help to make the right choice of printer. The characteristic features by which printers are distinguished are the following: print quality and speed, the amount of internal memory, the possibility of compatibility with computers of various generations and operating systems.
There are currently several types of printers:
* matrix
* inkjet
* laser
* sublimation.

Features of the dot matrix printer
The low cost of consumables is the main advantage of the matrix printer over the others. A significant drawback is the low quality and low print speed, while unpleasant noise continuously accompanies the printing process. The dot-matrix printer prints characters and signs with the help of a head knocking out dots with small needles on a special ink ribbon. The print color depends on the color scheme of the ink ribbon. Basically, these ribbons are black, but you can find ribbons that give blue or purple color printing. The print speed of such printers is extremely slow and does not exceed 6 sheets per minute. Such printers are mainly suitable for printing texts.

Inkjet printers and features of their work
The optimal price-quality ratio in work and consumables makes the choice of an inkjet printer the most rational. Replacement parts for an inkjet printer are decent and can be half the cost of the entire printer. The basis of the inkjet printer is the application of many droplets of ink on paper. Inkjet printers are available in black and white, three, four or seven-color version. Such printers perfectly print photos and color pictures. Typical inkjet print speeds of up to ten pages of text and up to five color pages per minute. Inkjet printers are great for working at home. Moreover, the cost and quality of color printing of inkjet printers greatly wins in comparison with other types of printers.

Features of laser printers.
Laser printers are good for printing houses, offices, or where you need to print quickly and a lot. Print speed – from 15 to 40 sheets per minute. The printing resource of laser printer cartridges is quite large, and after-sales service is relatively inexpensive. These factors determine the versatility of such a printer rather low cost per page.

Among printers, sublimation printers are known.

This type of printer is most common among photographers, as its technology of work allows you to work on materials of various structures, for example, fabric, ceramics, photo paper. True, such a pleasure as printing on a sublimation printer is the most expensive among other printers. The principle of operation of the printer is the evaporation of dyes from films, forming an image. Sublimation printers have a high print speed and compact size. Most often, sublimation printers are used in advertising agencies and design studios.
