paper-size=paper-size: Paper size, either as a symbolic name (i.e., letter or a4) or specific measurements (i.e., 8-1/2x11 or "210 x 297". See Paper sizes. Default: letter.
orientation=orientation: Either portrait or landscape. Default: portrait.
left-margin=dimension
right-margin=dimension
top-margin=dimension
bottom-margin=dimension: Sets the margins around the page. The headers, if enabled, are not included in the margins; they are in addition to the margins. For a description of dimensions, see Dimensions. Default: 0.5in.
