# Class PresentationDirection

java.lang.Object
javax.print.attribute.EnumSyntax
javax.print.attribute.standard.PresentationDirection

All Implemented Interfaces:
  `Serializable, Cloneable, Attribute, PrintJobAttribute, PrintRequestAttribute`

public final class PresentationDirection extends EnumSyntax implements PrintJobAttribute, PrintRequestAttribute
Class `PresentationDirection` is a printing attribute class, an enumeration, that is used in conjunction with the `NumberUp` attribute to indicate the layout of multiple print-stream pages to impose upon a single side of an instance of a selected medium. This is useful to mirror the text layout conventions of different scripts. For example, English is "toright-tobottom", Hebrew is "toleft-tobottom" and Japanese is usually "tobottom-toleft".

IPP Compatibility: This attribute is not an IPP 1.1 attribute; it is an attribute in the Production Printing Extension ( PDF) of IPP 1.1. The category name returned by `getName()` is the IPP attribute name. The enumeration's integer value is the IPP enum value. The `toString()` method returns the IPP string representation of the attribute value.
