/**
* A set of attributes which control a print job.
* <p>
* Instances of this class control the number of copies, default selection,
* destination, print dialog, file and printer names, page ranges, multiple
* document handling (including collation), and multi-page imposition (such
* as duplex) of every print job 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 print dialog type to
* the cross-platform, pure Java print dialog, use the following code:
* <pre>
* import java.awt.JobAttributes;
*
* public class PureJavaPrintDialogExample {
* public void setPureJavaPrintDialog(JobAttributes jobAttributes) {
* jobAttributes.setDialog(JobAttributes.DialogType.COMMON);
* }
* }
* </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.
