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