Laser printers use toner powder instead of ink to produce prints in both monochrome and color.
The key to how laser printers work is understanding the drum, a cylindrical, photosensitive component that allows the laser to pick up toner through static electricity. When you switch on your laser printer, the drum is negatively charged. When exposed to light, the drum loses its negative charge. The laser assembly inside laser printers is pointed at drum, drawing a pattern of positively charged dots while the drum rotates slowly, attracting the negatively charged toner. Then, the toner meets the paper as the drum rotates and it is heated with hot rollers to fuse the toner onto the paper.
Like inkjet printers, laser printers are sold as all-in-one units as well. Some also have features like dual-band Wi-Fi and double-sided printing, too, as well as enhanced security features (yes, your printer is a network security concern!). To save money, you can purchase a monochrome laser printer if you know you don’t care to print in color.
