Use the PaperOrientation property to control whether a document prints in portrait or landscape mode. Setting it to PaperOrientation.Landscape rotates the printable area so the longer edge runs horizontally - perfect for wide tables, timelines, and presentation slides.
Orientation is applied at the driver level before the content is rasterized, so the entire page layout adjusts automatically. Combine this setting with PaperSize to get precise control over how your content fills the physical sheet, avoiding awkward cropping or excessive white space.
