/**
 * Class ColorSupported is a printing attribute class, an enumeration, that
 * identifies whether the device is capable of any type of color printing at
 * all, including highlight color as well as full process color. All document
 * instructions having to do with color are embedded within the print data (none
 * are attributes attached to the job outside the print data).
 * <P>
 * Note: End users are able to determine the nature and details of the color
 * support by querying the {@link PrinterMoreInfoManufacturer
 * PrinterMoreInfoManufacturer} attribute.
 * <P>
 * Don't confuse the ColorSupported attribute with the {@link Chromaticity
 * Chromaticity} attribute. {@link Chromaticity Chromaticity} is an attribute
 * the client can specify for a job to tell the printer whether to print a
 * document in monochrome or color, possibly causing the printer to print a
 * color document in monochrome. ColorSupported is a printer description
 * attribute that tells whether the printer can print in color regardless of how
 * the client specifies to print any particular document.
 * <P>
 * <B>IPP Compatibility:</B> The IPP boolean value is "true" for SUPPORTED and
 * "false" for NOT_SUPPORTED. 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>
