Using the optional duplex printing accessory for
two-sided printing
The optional duplex printing accessory (figure 3-3), enables you to
print on both sides of a page. In two-sided printing, known as duplex
printing or duplexing, the back side of the page is printed first. Then
the page is sent through the duplex printing accessory, where it is
flipped over and sent back through the printer for printing on the front.
Note Although the printer detects the presence of the duplex printing
accessory, you must still specify duplex options in your software
application or in the printer driver in order to print on both sides of the
page.
