14  * Class Compression is a printing attribute class, an enumeration, that
15  * specifies how print data is compressed. Compression is an attribute of the
16  * print data (the doc), not of the Print Job. If a Compression attribute is not
17  * specified for a doc, the printer assumes the doc's print data is uncompressed
18  * (i.e., the default Compression value is always {@link #NONE
19  * <CODE>NONE</CODE>}).
20  * <P>
21  * <B>IPP Compatibility:</B> The category name returned by
22  * <CODE>getName()</CODE> is the IPP attribute name. The enumeration's
23  * integer value is the IPP enum value. The <code>toString()</code> method
24  * returns the IPP string representation of the attribute value.
