Duplex printing means that your printer supports printing on both sides of the paper. Printers that are only capable of printing out documents single-sided are sometimes called simplex printers.

What is simplex and duplex in printing?

Some printers can print on one side of the sheet (simplex printing) or on both sides (duplex printing). To see whether your printer can print in duplex mode, see the documentation provided with the printer.

What does simplex mean on a printer?

Simplex printing is the industry term used to describe one-sided printing. Typically, simplex printing is one-sided printing where the printed image (when viewed) has the long edge of the print media to the left.

Duplex Printing, also known as double-sided printing, is a term used for printing on both sides of the paper. This is achieved either automatically if your printer supports duplex printing, or even manually if you decide to flip the pages and print both sides.
