  34  * Class OrientationRequested is a printing attribute class, an enumeration,
  35  * that indicates the desired orientation for printed print-stream pages; it
  36  * does not describe the orientation of the client-supplied print-stream
  37  * pages.
  38  * <P>
  39  * For some document formats (such as <CODE>"application/postscript"</CODE>),
  40  * the desired orientation of the print-stream pages is specified within the
  41  * document data. This information is generated by a device driver prior to
  42  * the submission of the print job. Other document formats (such as
  43  * <CODE>"text/plain"</CODE>) do not include the notion of desired orientation
  44  * within the document data. In the latter case it is possible for the printer
  45  * to bind the desired orientation to the document data after it has been
  46  * submitted. It is expected that a printer would only support the
  47  * OrientationRequested attribute for some document formats (e.g.,
  48  * <CODE>"text/plain"</CODE> or <CODE>"text/html"</CODE>) but not others (e.g.
  49  * <CODE>"application/postscript"</CODE>). This is no different from any other
  50  * job template attribute, since a print job can always impose constraints
  51  * among the values of different job template attributes.
  52  *  However, a special mention
  53  * is made here since it is very likely that a printer will support the
  54  * OrientationRequested attribute for only a subset of the supported document
  55  * formats.
  56  * <P>
  57  * <B>IPP Compatibility:</B> The category name returned by
  58  * <CODE>getName()</CODE> is the IPP attribute name.  The enumeration's
  59  * integer value is the IPP enum value.  The <code>toString()</code> method
  60  * returns the IPP string representation of the attribute value.
  61  * <P>
