In [2-Sided Print], select [Flip on Long Edge] or [Flip on Short Edge].
Click [OK].
Two-sided printing may not be available, depending on the paper type.
The orientation selected in the application (such as the print settings of Word) is prioritized when printing. If the two-sided printing orientation is not selected in the application, the two-sided printing orientation selected here is given priority over the front and back print orientation of the paper.
If something other than [Flip on Long Edge] or [Flip on Short Edge] is selected in the application, one-sided printing is performed.
