13  * A set of attributes which control the output of a printed page.
14  * <p>
15  * Instances of this class control the color state, paper size (media type),
16  * orientation, logical origin, print quality, and resolution of every
17  * page which uses the instance. Attribute names are compliant with the
18  * Internet Printing Protocol (IPP) 1.1 where possible. Attribute values
19  * are partially compliant where possible.
20  * <p>
21  * To use a method which takes an inner class type, pass a reference to
22  * one of the constant fields of the inner class. Client code cannot create
23  * new instances of the inner class types because none of those classes
24  * has a public constructor. For example, to set the color state to
25  * monochrome, use the following code:
26  * <pre>
27  * import java.awt.PageAttributes;
28  *
29  * public class MonochromeExample {
30  * public void setMonochrome(PageAttributes pageAttributes) {
31  * pageAttributes.setColor(PageAttributes.ColorType.MONOCHROME);
32  * }
33  * }
34  * </pre>
35  * <p>
36  * Every IPP attribute which supports an <i>attributeName</i>-default value
37  * has a corresponding <code>set<i>attributeName</i>ToDefault</code> method.
38  * Default value fields are not provided.
