Definition – What does Laser Printer mean?
A laser printer is a type of printer that uses laser and electrical charge model to transfer images and text onto paper. It increased the neatness of print projects with typical resolutions of 600 dots per inch and higher. However, contrary to popular belief, the laser or light does not actually burn the text or image onto the paper. Instead, the paper passes, the laser beam fires at the surface of the cylindrical drum known as a photoreceptor. This drum has an electrical charge that is reversed in areas where the laser beam hits it. By reversing the charge in areas of the drum, the laser beam can print the image onto the photoreceptor.

Once the image was created on the drum, it is coated with toner from the cartridge. The toner is black in most of the cartridges but may be cyan, magenta, and yellow — the positively charged toner grips to areas of the drum that have negatively charged by the light. When paper passes through the printer, the drum is given a strong negative charge that enables the toner to transfer to the paper, and the result is a clean copy of the pattern on the paper.
Because laser printers do not use ink or any other liquid, they have less image smearing problems than inkjet printers. While laser printers and toner cartridges cost more than inkjet printers and ink cartridges, most of the laser cartridges last numerous times longer than ink cartridges that makes their cost per page about equal. For this, most of the businesses tend to use laser printers, while consumers are more likely to use inkjet printers.
