Design and operation of various designs of printers
Manufacturing companies producing various types of printers, which are based on various printing technologies. This can be inkjet, laser, LED and Solid and sublimation printing. For a simple user most familiar LED, laser and inkjet printers, so in this section of the article, they will be examined in more detail.
LED devices
LEDs in recent years gradually come in all spheres of modern life, it concerns the electric lighting and decoration of premises, automotive engineering and landscape design.

LED light sources are not ignored and equipment for various purposes, including it touched copying, printing and copying equipment. Based LED printer or drum design is, in other words, the printing roller whose surface is susceptible to light. Under the influence of light waves dye streams adheres to the drum surface and then transferred to solid medium (paper, cardboard, thermal, etc.). Application of the dye occurs through the drum pressing the used carrier, and then - the quick-drying, fixing the ink on its surface. LEDs in a given structure placed on the surface of the printing shaft.

The advantages of this type of printers are such factors as:
- small size, compared to laser counterparts;
- Use reliability due to simplicity of design;
- lengthy periods of operation;
- They are environmentally friendly devices;
- relatively low cost of printing;
- less expensive items related to the repair and maintenance than laser counterparts;
- the cost is lower than that of other devices, especially noticeable in the color printing models.
The disadvantages of LED printers include:
- the complexity of the control of the brightness of LEDs used, thus affecting the quality of obtained images;
- low accuracy illuminates the points on the surface of a solid carrier;
- Print speed is lower than laser counterparts.
Laser printers are available in different sizes with different technical characteristics and uses
laser printers
Devices of this type also have in their construction drum, and these are similar to the LED counterparts. The difference lies in the principle of dye transfer and a method of focusing a laser beam on a hard copy (paper). In printers of this type of laser beam is directed through a system of focusing lenses and mirrors, and the drum made of aluminum, on whose surface applied material sensitive to light rays. Under the action of the laser is a change of electrical conductivity of this layer.

laser printer cartridge is composed of two elements, this toner, which contains a colorant, and a drum whose surface is irradiated with a laser.

The principle of operation of such devices is as follows:
- at the beginning of the printing process payment device processes the image and sends the obtained information on the original data block transfer;
- the drum rotates, receives light pulses on a surface corresponding to a digitized image;
- under the action of pulses changes the electrical conductivity of the upper layer of the drum, and in these areas the toner is attracted to the printing surface of the shaft;

Different manufacturers of toner produced with unique properties (density, grain size, magnetic, etc.), so you can not replace dye one firm to another output.

- paper, before entering into contact with the printing roller, receives static discharge, which is achieved by the presence of special roller;
- shaft rotating in contact with the dense support and the toner is transferred on its surface, followed by drying it.

There are two options for forming the image when, in one case the toner is positively charged, and the drum negative - is the most common method, and vice versa, when the toner is negatively charged, and the drum - positively.
The advantages of laser printers are the following figures:
- high print quality, especially text documents in black and white;
- Print speed is significantly higher than other counterparts;
- the cost of printed materials is lower than that of inkjet counterparts.
Among the shortcomings should be noted:
- inability cartridge refilling at home;
- high price;
- quality color images, especially for photo printing, significantly lower than that of inkjet models.

There is the concept of "monochrome printer", which implies a black-and-white printing text and images with few shades of gray and other colors of the spectrum. Currently, the monochrome version available laser devices for office use.
Inkjet models are indispensable for printing on different types of media
inkjet models
Inkjet printers are currently available only in color, in this case, depending on the destination, they are classified as:
- «Color» - using 4 color dye;
- «Photo» - working with 6 or more colors.
The main unit of this type of device is the printing head is located on a movable carriage. The dye from the cartridge is supplied to the print head and the carriage is adapted to move relative to the surface of dense media. The principle of operation of inkjet printers is based on the extrusion of ink through a nozzle onto the surface of paper according to the printing technology used in the specific model:
- thermal - paint squeezed due to bubbles formed in it by means of special heating element arranged in dyuzah;
- piezo - used piezoelectric crystal, dilatory diaphragm creates a pressure, expelling the ink to the media.

Inkjet Printers brand «Canon» and «HP» use in their work thermal technology and brand «Epson» - piezoelectric.
Paint in devices of this type is placed in special cartridges, which are of two types:
- separate - when one color of paint is placed in a separately installable package;
- combined - in one case a couple of different colors are placed.
The cartridge consists of a tank in which ink is placed, and a head for applying the dye to the print head unit and chip allowing their coordinated operation.

The printer models using combined cartridges, using one of the colors is necessary to replace the entire cartridge completely.
When large volumes of print for ease of use and reduce costs for the purchase of inkjet cartridges SPNCH system is used, which assumes ink supply "gravity" of containers with the paint to the capsules on the printing needle mechanism.

The advantages of inkjet models include such factors as:
- low cost;
- the ability to perform self-refilling cartridges in a house and office,
- versatility, allowing printing in black-and-white and color range;
- small size and weight;
- most models combined in a single package multiple devices (copier, printer, scanner);
- the possibility of using different types of solid media (paper, cardboard, fabric, photo paper, etc.);
- high image quality.
Separate ink cartridges for inkjet devices
The disadvantages include:
- small volume filling capacity cartridges require frequent replacement in intensive use mode;
- low-speed printing, compared with analogues of other types;
- the high cost of ink cartridges.

Using SPNCH system overcomes a number of shortcomings associated with low volume filling capacity and high costs of cartridges.
Laser, inkjet or LED - what to choose for the house
The criteria on the basis of which you can choose a printer for home use, may be a few, due to modes of operation, the intensity of the use and purpose of such equipment, as well as a potential budget user.
The availability of original ink cartridges for inkjet printers, allowing them to fill their own
However, due to the fact that at home you need to possibly combine all of these criteria, the choice is up to the individual user, choose the model of indicators such as:
- The best types of print quality of the device. Inkjet printers print equally well as the text information as well as photos, cards and other color images. Laser models do well to comparable tasks, with the exception of photos that can be obtained not as clear and colorful, which is associated with a lower color reproduction images.
- Top grade appliances. Reliability of the device is guaranteed by its manufacturer, so it is difficult to mention one or another type of printers in this category. However, with heavy use of the most commonly used laser models, and at home use - jet.
Availability of Wi-Fi-module in the latest generations of models allows you to control devices remotely
- Most printers on the print speed. Print speed laser models is significantly higher than that of the jet. The usual type of laser device prints per minute up to 15 sheets of A4, while the jet counterpart this figure depends on parameters such as volume, resolution and print quality.
- Best devices from the budget possibilities. Inkjet models, even in the high-end versions, significantly cheaper analogues with conventional laser bundle. However, due to the fact that the toner stock in such devices is sufficient for increasing the number of working operations, their maintenance costs are lower than the "inkjets."
Leading manufacturers of conventional models, and photo printers for the home
