* SECTION:gtkpapersize
* @Short_description: Support for named paper sizes
* @Title: GtkPaperSize
* @See_also:#GtkPageSetup
*
* GtkPaperSize handles paper sizes. It uses the standard called
* <ulink url="http://www.pwg.org/standards.html">"PWG 5101.1-2002 PWG: Standard for Media Standardized Names"</ulink>
* to name the paper sizes (and to get the data for the page sizes).
* In addition to standard paper sizes, GtkPaperSize allows to
* construct custom paper sizes with arbitrary dimensions.
*
* The #GtkPaperSize object stores not only the dimensions (width
* and height) of a paper size and its name, it also provides
* default <link linkend="print-margins">print margins</link>.
*
* Printing support has been added in GTK+ 2.10.
