The laser printer is one of the latest computer printer models. It is characterized by the high quality printing of both texts and images on plain paper. It can print both in black and white and in color, clearly differentiating itself from previous models such as the ink jet printer that did not allow high definition of the graphics.
The first laser printer was created in 1969 by the Xerox company, but it was not until recent times that this printer became popular with regular users of computing machines. On the other hand, the rapid development of this type of printer is what allows today to make large-size prints on other types of materials in a proportionally insignificant time.
The laser printer works through a photosensitive device, that is, it works with the presence of a certain type of light. A system of internal mirrors is what allows a small laser beam to be activated, being able to determine the direction and intensity of the print. The colors available for a laser printer are black, cyan, magenta, and yellow.
An important element of any laser printer is the powder known as toner that acts like the ink in any other regular printing system. This dry ink is applied to the paper by means of positive and negative charges that attract or repel it through the transfer drum. Finally, that dry powder or ink is fixed on the paper thanks to the work of rollers that will ensure greater quality and durability to the printing. All these tasks are performed almost simultaneously because they take very little time between one and the other. This adds another element of great importance to laser printing: the speed that makes the printed product ready in a matter of seconds or minutes depending on the size.
