The device and principle of operation of a black-and-white printer
Laser printers and today they remain the most reliable, fast and high-quality type of printing that can be used both at home and in the office. The inside of the laser printer is a set of shafts and rollers. One of the most important elements is the drum unit. At first, our future image is formed on it. If we describe the printing process in stages, it looks like this: the printed document is loaded into the printer's memory. The first sheet of paper is fed by an automatic mechanism. At this point, the fusing unit is warming up. When the paper is ready to come up with its edge to the drum, a charge is applied to it with the help of a laser in certain places that need to be printed. The drum unit rotates further and contacts the toner bottle through the other drum. The areas that have been charged attract particles of toner, a special fine powder for printing. With its help, text or an image is formed on the drum. Then the drum unit turns further and comes into contact with the paper, onto which the toner is transferred. The sheet then travels to a fusing point where the finest toner particles are fused into the paper structure. This is how the entire sheet is printed.
This is the simplest print job algorithm laser printer. In different models from different manufacturers, it may differ insignificantly, but the general principle always remains the same.
Criterias of choice
There are plenty of criteria for choosing a laser printer. How it will be used will largely determine which options are best to choose. Let's see what you should pay attention to first.
Maximum format and resolution
Size refers to the maximum paper size that the printer can handle. The most common is A4. It has a size of 210 by 297 mm. A3 is less common - 297 by 420 mm. And documents of this format are rarely printed.
Resolution is the number of dots per inch.
In essence, it reflects the quality of the resulting image. Usually indicated in specifications as: 600 × 600 dpi. The more numbers, the better.
Print speed and operating system support
Print speed is defined as the number of pages printed per minute. Typically this setting ranges from 16 to 26 ppm. High speed is relevant where you need to print a large amount of documentation. For example, in the office.
Often manufacturers indicate the speed of the first page out. This time can vary from 5 to 15 seconds and shows how long it takes for the printer's fuser to warm up. The shorter the time, the better.
Power consumption and wireless connectivity
Power reflects the amount of power consumed at the time of printing and in standby mode. The power value of a simple printer can start from 150-200 watts in operation and about 2 watts when waiting. More serious multifunction devices can draw from 500 watts.
Wireless connectivity is not uncommon these days and is mainly implemented using Wi-Fi. Naturally, wireless connectivity is much more convenient than wires. Therefore, when choosing such functionality, it can be considered a priority.
Cartridges, their refueling and the cost of this operation
Consumables are one of the most important parameters that ultimately affect the cost of a printed sheet. Laser printer cartridges are usually refillable, but recently there has been a trend towards when special chips are installed on them, which, after the end of the toner, block the possibility print.
Therefore, you have to turn to specialists who can carry out chipping so that the cartridge again has the opportunity to print. But there are models that do not require chipping and can be easily refilled. It is much more profitable than buying a new cartridge every time.
Weight, dimensions and capacity of trays
Weight should influence the choice to a lesser extent. The device will calmly stand in one place it should be and it is unlikely that it will have to be moved often. Size has a bigger impact. In confined spaces, a compact printer will be more beneficial than a bulky MFP.
Tray capacities are more relevant for offices and printers designed for large volumes of work. They allow you to increase the number of printed sheets per print cycle. On some models, in addition to standard trays, you can find extended versions. For the home, standard types of trays are also perfect.
