 * Class PrinterMoreInfoManufacturer is a printing attribute class, a URI,
 * that is used to obtain more information about this type of device.
 * The information obtained from this URI is intended for end user
 * consumption. Features outside the scope of the Print Service API
 * can be accessed from this URI (e.g.,
 * latest firmware, upgrades, service proxies, optional features available,
 * details on color support). The information is intended to be germane to
 * this kind of printer without regard to site specific modifications or
 * services.
 * <P>
 * In contrast, the {@link PrinterMoreInfo PrinterMoreInfo} attribute is used
 * to find out more information about this specific printer rather than this
 * general kind of printer.

 * The category name returned by <CODE>getName()</CODE>
 * gives the IPP attribute name.
