A laser printer is suitable when you often print large documents. These printers use toner cartridges instead of cartridges. Toner cartridges are more affordable and more efficient than cartridges. Laser printers are often also faster than inkjet printers. Want to copy or scan as well? Choose an all-in-one laser printer. If you often scan or copy large reports, choose a laser printer with an automatic document feeder. You can also save paper with a laser printer that prints in duplex automatically.
