33 * Class PresentationDirection is a printing attribute class, an enumeration,
34 * that is used in conjunction with the {@link NumberUp NumberUp} attribute to
35 * indicate the layout of multiple print-stream pages to impose upon a
36 * single side of an instance of a selected medium.
37 * This is useful to mirror the text layout conventions of different scripts.
38 * For example, English is "toright-tobottom", Hebrew is "toleft-tobottom"
39 * and Japanese is usually "tobottom-toleft".
40 * <P>
41 * <B>IPP Compatibility:</B> This attribute is not an IPP 1.1
42 * attribute; it is an attribute in the Production Printing Extension
43 * (<a href="ftp://ftp.pwg.org/pub/pwg/standards/pwg5100.3.pdf">PDF</a>)
44 * of IPP 1.1. The category name returned by
45 * <CODE>getName()</CODE> is the IPP attribute name. The enumeration's
46 * integer value is the IPP enum value. The <code>toString()</code> method
47 * returns the IPP string representation of the attribute value.
