The printer belongs to the category of peripheral output devices and is used to transpose data from the computer to paper, a document, a picture or any other graphic file, an email, an article, etc. Printers are classified according to several criteria, for example depending on the purpose (printing / printing) and the speed, procedure, maximum size of the paper on which it is printed and others. A laser printer is a common type of printer that reproduces text and graphics on paper quickly and in high quality.
Like digital photocopiers and multifunction printers, laser printers use xerographic printing technology, but differ from analog photocopiers in that the image is produced by direct scanning with a laser beam along the photoreceptor. Laser printers make the best quality prints, but they are much more expensive, most laser printers print only black and white, but there are also much more expensive models that can print in color. As we know the resolution is the number of dots that can be printed on a unit of area and is expressed in dots per inch (dpi - dot per inch). Obviously, the higher the resolution, the better the quality of the printed image. Normally, the resolution used for a monochrome laser printer is 600 dpi, but there may be some documents that require 1200 dpi.
The surface of this drum passes through a bath of fine particles of dry plastic powder. Due to the fact that the printing nozzles on the printhead are extremely small, it may happen that some of them dry out on the ink, which will lead to poor print quality. So we will clean the print head to improve the print quality.
5 advantages of a laser printer:
The printing speed of a laser printer can be up to 3 times faster than an inkjet printer. If an inkjet printer can print 4-5 pages per minute (ppm) a laser printer can reach 16 ppm.
Print quality - laser printers are also very good at printing text documents, faithfully rendering a very large number of fonts, regardless of font size.
Silence - although the noise produced by the printer cannot be considered a major disadvantage in the case of a machine purchased for personal use, given that the printer is installed in an office, its use could disrupt the concentration of employees. With the development of technology, laser printers have become increasingly quiet, an advantage to consider if you want to install it in an office.
Lower printing costs - although laser printers are more expensive than inkjet printers, it is also important to consider the cost of cartridges. Even though they are more expensive, laser cartridges are capable of printing up to 2,000 pages, compared to only 100-200 pages of an inkjet printer.
In both cases, you can reload the same cartridges several times, which can help reduce operating costs and gradually pay off the investment.
