You can choose the type of layout for the pages in the job.
To change the page orientation from a vertical layout to a horizontal layout:
Click Layout on the left side of the screen.
Select the layout type and go to Orientation.
Select Landscape from the list.
Important: The selected orientation must match the orientation of the pages in the print file.
If there are combined layouts in the print file, you must set it to match the orientation
of most pages. Jobs submitted to virtual printers must have the same orientation as the virtual printer. Otherwise, the job might not print as expected.
For example, if the print file has ten pages and seven pages are displayed in portrait
mode and three in landscape mode, you must set the orientation to portrait, to match
the orientation of most pages.
