/**
* Class Media is a printing attribute class that specifies the
* medium on which to print.
* <p>
* Media may be specified in different ways.
* <ul>
* <li> it may be specified by paper source - eg paper tray
* <li> it may be specified by a standard size - eg "A4"
* <li> it may be specified by a name - eg "letterhead"
* </ul>
* Each of these corresponds to the IPP "media" attribute.
* The current API does not support describing media by characteristics
* (eg colour, opacity).
* This may be supported in a later revision of the specification.
* <p>
* A Media object is constructed with a value which represents
* one of the ways in which the Media attribute can be specified.
* <p>
* <B>IPP Compatibility:</B> The category name returned by
* <CODE>getName()</CODE> is the IPP attribute name. The enumeration's
* integer value is the IPP enum value. The <code>toString()</code> method
* returns the IPP string representation of the attribute value.
* <P>
