Duplex printing is a printing method that allows a printer to print on both sides of a sheet of paper automatically. This feature helps save paper and reduces printing costs, making it an eco-friendly option. Many modern printers come with duplex printing capabilities, which can be set up easily through the printer's settings. Using duplex printing can also enhance the organization of printed materials, such as reports or brochures, by allowing information to be presented on both sides of the page. This method is commonly used in offices, schools, and homes for various printing tasks.
