How can you tell if the printer has a duplexing unit on it (without having to connect a PC and testing it). We have multiple HP LaserJet printers, 2100series, and some have extra trays and/or some have duplexing units. How can you tell? What is physically different?

A duplexer basically takes the output and rotates it and feeds it back inside. So look for attachments that goes to paper-output paths and such.

In general, HP's add "D" suffix to machines that are shipped with duplexers.

If I remember right, the 2100 duplexer are added to teh back of the printer, so its much deeper than the normal model.
