+class Win32PrintingSurface(:class:`Surface`)
+============================================
+
+The Win32PrintingSurface is a multi-page vector surface type.
+
+.. class:: Win32PrintingSurface(hdc)
+
+ :param hdc: the DC to create a surface for
+ :type hdc: int
+ :returns: the newly created surface
+
+ Creates a cairo surface that targets the given DC. The DC will be queried
+ for its initial clip extents, and this will be used as the size of the
+ cairo surface. The DC should be a printing DC; antialiasing will be
+ ignored, and GDI will be used as much as possible to draw to the surface.
+
+ The returned surface will be wrapped using the paginated surface to provide
+ correct complex rendering behaviour; :meth:`.show_page` and associated
+ methods must be used for correct output.
+
+
