Simply so, what is a duplexer on an HP printer?

A printer duplexer is a separate, usually removable hardware device that comes with a printer or -- if your printer has duplex printing capabilities -- one that you can purchase as an add-on accessory. Printer drivers are available for download from manufacturers' and third-party websites.

Additionally, what does duplexer mean? A duplexer is an electronic device that allows bi-directional (duplex) communication over a single path. In radar and radio communications systems, it isolates the receiver from the transmitter while permitting them to share a common antenna.

Consequently, how does a printer duplexer work?

Duplex printing means that you can print on both sides of the paper with your printer either automatically or manually by turning the paper over after the first side has printed. Simplex printing, on the other hand, only allows for printing on one side of the paper.

Why is my printer not printing both sides?

To find out whether your printer supports duplex printing, you can check your printer manual or consult your printer manufacturer, or you can do the following: Click Print. Under Settings, click Print One Sided. If Print on Both Sides is available, your printer is set up for duplex printing.
