Print duplex (double-sided) jobs
You can print a single-sided job as a duplex (double-sided) job by specifying a duplex setting, which determines the orientation of printed images.
Note: The duplex settings that appear vary according
to the printer.
If the document has an odd-numbered page count, this option inserts a blank page at the end of the job.
- Open Printing preferences. (See Open Printing preferences.)
- Click the Layout icon.
- Select one of the duplex settings:
Print the top of the image on Side 1, on the same edge of the page as the top of the image on Side 2.

Print the top of the image on Side 1, on the opposite edge of the page from the top of the image on Side 2.
