These printers use a laser to stick a powdered toner to paper. Lasers are the workhorse of the printing world – they’re incredibly fast and powerful (faster than inkjets), so they’re good for large volumes of black and white printing. While they’re perfectly capable of delivering colour, they don’t it as well as inkjet printers do. But they can print more pages at a given time and they can handle thousands of pages per month without crashing.
