Definition - What does Duplex Printing mean? Duplex printing is the feature present in multifunction printers and computer printers which allows printing on both sides of paper. Only printers with built-in duplex capability allow users to print double sided without manually flipping over the page.
Often, on MFPs, this is combined with a reversing automatic document feeder (RADF) to allow for duplex scanning also. Higher volume printers may in essence have two print engines in a single device, and are able to print both sides of the paper in a single pass.ingle-sided printers can still print duplex jobs; however, the user has to manually turn the print job over and re-initialize the printing of the document. In that process, it is important to determine which edge and side the printer prints on.
