What does duplexing mean?
Duplexing is a technical noun for arranging a connection or device so that it can operate in two directions. In telecommunications and data networking, duplexing may mean simultaneous sending and receiving, as in full duplex, or alternating transmission, as in half duplex. The distinction matters because simultaneous exchange avoids the turn-taking delay associated with half-duplex operation. In printing, duplexing refers to placing content on both sides of a sheet, whether done manually or automatically by a printer or copier. The word is chiefly used in technical documentation, equipment settings, and discussions of network performance. It is more specific than simply “two-way”: a system must support reverse-direction communication, although it need not do so at the same instant. For general audiences, “full duplex” is often more familiar than the gerund “duplexing,” while the printing sense is increasingly familiar through multifunction office equipment.
The operation or method of communicating in both directions over a connection, or of printing on both sides of a sheet.
"Full duplexing allows both computers to exchange data without waiting for the other to finish."
The telecommunications sense is most common in technical documentation, while the printing sense is common in office and hardware contexts.
To operate a connection in two-way mode or to print a document on both sides.
"The office duplexed the handout rather than using two printers."
The verb form is especially associated with printing workflows and may sound informal outside technical settings.
Rare; duplexing is normally an uncountable noun denoting a process, method, or mode.
"The diagnostic report records repeated duplexings between the two endpoints."
One connection, two directions—and in full duplex, no need to wait for your turn to speak.

Where does duplexing come from?
Duplexing is an English formation from duplex, meaning “double” or “twofold,” with the suffix -ing. Latin duplex was formed from duo, meaning “two,” and -plex, the element associated with folding. Related words in the Latin-derived vocabulary include double, duplicate, duplicity, and duple.
How duplexing is actually used
Duplexing is chiefly a technical term used in networking, telecommunications, printing, and equipment documentation. In communications, it may encompass both simultaneous two-way transmission and alternating two-way transmission; the latter is specifically called half duplex. In North American office usage, duplex by itself commonly refers to double-sided printing.
Easily confused with duplexing
A duplex is a device, connection, or arrangement capable of two-way operation, whereas duplexing is the process or method of operating in that mode.
