Features of black and white laser printers

Today the printer is one of the necessary devices for work and study, which is used not only in the office, but also at home. At the same time, a huge number of varieties of such devices are presented on the modern market. Perhaps, the most common type is a black and white laser type printer. Let's consider the main characteristics of such a printing mechanism.

Black and white laser printers are very popular with usersbecause they are distinguished by such characteristics as reliability, high speed of operation and high-quality printing.

If we talk about the design and internal structure of the monochrome device, it is important to note that it consists of a set of shafts and rollers... The most important part of the printer is also drum, thanks to this element, an image is formed, which will later be printed.

The principle of operation of the device is based on several key processes.

1. First, a document is loaded into the printer's memory to be printed.
2. After that, a specialized automatic mechanism is activated, with the help of which paper is fed into the device. By the time the first sheet appears, the fusing unit is also in operation.
3. By means of a specialized laser, which is an integral part of the device, a detailed charge is applied to the imaging drum exactly in those places that need to be printed.
4. As it turns, the drum unit touches the toner bottle (powder needed for printing).

Black and white laser printers are used for a wide variety of purposes... For example, they can be applied in office for printing all kinds of business documents (for example, statements, reports, and the like). And they are also actively used at home - no student or schoolchild can do without a printer. In addition, this device is indispensable in some industrial plants.

Due to the great popularity of black-and-white laser category printing devices, a large number of modern equipment manufacturers began to produce such mechanisms. At the same time, given that printers can be used for a variety of purposes, they create many types of devices.

So, there are printers that are used for high volume printing. They are often called industrial. In contrast to such devices on the market, you can find non-industrial (or household) designs that are intended for home use. These varieties differ in functionality and size.

Among other things, specialists separate printers depending on what format documents they are capable of printing. The most common type is A4 printers. However, other formats can be used for specific purposes (for example, A3 or A2 and others).

Thanks to such a wide variety of printer models, each user will be able to choose for himself such a type of printing device that will meet his individual needs.

When choosing a printer, special attention should be paid to manufacturer... It is recommended to give preference to only the best and proven brands that are popular and respected among users and professionals.

The market value of this device is about 9,000 rubles. There are many advantages to this price. First of all, it should be noted the presence of unpinned cartridges, thanks to which the process of refueling the mechanism will not require large material costs from you. In addition, the device has double-sided printing functionso you don't have to flip and reload the paper. It is worth noting that the Brother HL-L2340DWR model provides possibility of mobile printing.

This model is pretty budgetary, therefore it is available to many. However, even in spite of the low price, there are all the necessary functions. The model is suitable for both home use and for printing in a small office. The device is quite simple to operate, does not need additional painstaking settings... The design has a specialized wireless communication module. The process of replacing cartridges is not difficult at all, so almost anyone can handle it (even those who do not have specialized technical and technological knowledge). Depending on what you print (text, graphics or pictures), you can get from 20 to 60 pages per minute.

This device belongs to quite high price category. An important distinguishing feature of the printer is quiet workthat will not distract and inconvenience others. In addition, the manufacturer has provided for the possibility of complementing the device two paper trays (this can be done by the user at will). There is a function bilateral printing, as well as a Wi-Fi type router.

The disadvantages include quite complex initial setup process. And also some of the shortcomings note the large dimensions of the printer, so you should think in advance where you will put the mechanism.

Choosing a laser printer is quite difficult. It is important to be very careful and responsible for the selection and purchase of a device. In doing so, it is recommended to take into account several key parameters.

When buying a printer, first of all, you need to pay attention to the fact that it meets the main format standard, namely: had the ability to print A4 size documents (or 210 by 297 mm). Concerning permissions, then such BW devices cannot boast of high performance in this regard. The standard is considered to be a resolution of 600x600. Upgraded printer models with built-in interpolation function have a higher resolution - 1200x1200.

Laser printers, unlike other types of printing devices, have high printing speed. So, in 60 seconds the device can produce from 15 to 60 pages (the more exact number depends on the specific model). If we talk about the most budgetary models of printers, then the average print speed of such devices is about 20 pages per minute.

The power indicator reflects how much power the device is consuming. This figure can vary significantly and range from 150 to 500 watts. The exact number depends on what functions the printer has (the more functions, the more power consumption). With regard to connection types, modern printers can have different capabilities. For example, some models have wired COM, LAN or USB ports. And there are also models with a wireless connection type Bluetooth or Wi-Fi (AirPrint, Google Cloud Print).

When choosing a device, especially close attention should be paid to consumables, because they affect the cost of the printed sheet of the document. At the same time, you should not choose printers with the cheapest consumables, as this can negatively affect the final quality of the document. Better to give preference to the middle price category. Optimum toner yield is 1,200 pages. This means that just such a volume of printing is possible without refilling it.

The indicator of capacity of trays is of great importance in the event that you purchase a printer for printing on a large scale: the larger the capacity, the more sheets you can print in 1 cycle. The dimensions of the printer directly affect the usability of the device, and the choice depends on the availability of free space that you have. In general, it is recommended to give preference to devices with the most ergonomic design.

If you take into account all the factors described above, then in the end you will get a high-quality device that will serve you as long as possible and will meet all your needs.
