31+ * The <code>Paper</code> class describes the physical characteristics of
32+ * a piece of paper.
33+ * <p>
34+ * When creating a <code>Paper</code> object, it is the application's
35+ * responsibility to ensure that the paper size and the imageable area
36+ * are compatible. For example, if the paper size is changed from
37+ * 11 x 17 to 8.5 x 11, the application might need to reduce the
38+ * imageable area so that whatever is printed fits on the page.
