10 Best laser of 2019
Laser printer guide
Of the laser has proved to be the best alternative, especially in black and white printing, especially as it is in a qualitative sense a needle or inkjetis far superior. He is now also in the private sector very often used. In fact, in offices where the speed of printing is in demand, it is always the first choice.
Laser Printer – General
His name is the laser due to the then exclusively used technology. While in the past the laser beam was responsible for ensuring that the toner found its proper place on the paper, these tasks are now also taken over by liquid crystals (LCD) and light emitting diodes (LED). For this reason, there are both the LED printer and the LCD printer. Total sets laser a complete small computer that builds images before printing using a fast processor in a memory. The most important characteristic of the laser printer is a clear and very sharp picture. For this reason come laser especially in black and white printing often used.
The printing technology of the laser printer
The toner cartridge is at the heart of any laser printer because it is responsible for the image production unit. In this there is both the toner, which consists of a mixture of carbon black and heavy metals and is tailored to the particular printer model, as well as the photoconductor drum and rollers.
Will the laser Commissioned by the computer to print an image, the magnetic roller, which is magnetically attracted to the toner, sets in motion. The photoconductor drum ensures that the toner comes to exactly the point of the sheet that the print job requires. For this purpose, the photoconductive drum is coated with a material that can be negatively charged. The loses this charge when light falls on them. From this step of the laser printer, a laser printer, an LED and an LCD printer are different from each other.
In the laser printer, an image is drawn on the photoconductor drum by the laser beam. In all the places where the laser beam falls, the photoconductor drum loses its charge. A reflection mirror ensures that enough light falls on the drum.
Unlike the laser, an LED and an LCD printer require an additional light source.
All models have the same printing process. Once the drum is partially exposed, the magnetic roller approaches sound and is attracted to the photoconductive drum, leaving the sound hanging only where the drum is no longer negatively charged. The drum presses the sound onto the paper and passes the paper to the fuser unit, which burns the toner. Then the printing is finished and the paper is output.
Laser printer types
There are three different categories of laser printers: monochrome laser printers, color laser printers and multifunction laser printers.
Monochrome Laser Printers
Monochrome laser printers print exclusively in black and therefore also in gray gradations. Such a laser printer is the best possible choice for the office. Because this is much faster than an inkjet or color printer. And when color printing is not necessary, it’s far more cost effective.
Color Laser printers
In addition to black and white printing, a laser printer also produces color prints. For these, however, are special Color Laser printersnecessary, which have four toner cartridges in the colors magenta, cyan, gel and black. Color laser printers are recommended for CAD drawings and graphics because the print quality is very good. The color laser printers are a bit more expensive to buy than the monochrome laser printers or the inkjet printers. But these costs are offset by the low operating costs.
Multifunction Laser Printer
The Multifunction printers, also called MFP, provide printerwith integrated scannerThis means that these laser printers can also be used for copies in addition to paper printing. Some models are also equipped with a fax function. The multifunction laser printers are available both as black and white devices, and as a color laser printer.
The advantages of the laser printer
While the laser printers used to be seen only in large companies due to the high initial costs, these can now also be purchased by private individuals, as there are now also cheaper models for private use. The advantages of a laser printer compared to the other printer types are many.
The biggest advantage is the significantly sharper picture. This facilitates the readability of texts as well as prints an image that is more saturated and rich in contrast.
Meanwhile, the cost of a laser printer are not so high, so even models under 100 € can be found.
The operating costs for a laser printer are significantly lower than those for an inkjet printer. For this reason, a laser printer turns out to be even cheaper for a longer period of time.
The higher speed of a laser printer is also among its advantages. Any business where speed is very important benefits from the high speed.
