 * Class {@code PrinterMoreInfo} is a printing attribute class, a {@code URI},
 * that is used to obtain more information about this specific printer. For
 * example, this could be an HTTP type {@code URI} referencing an HTML page
 * accessible to a web browser. The information obtained from this {@code URI}
 * is intended for end user consumption. Features outside the scope of the Print
 * Service API can be accessed from this {@code URI}. The information is
 * intended to be specific to this printer instance and site specific services
 * (e.g. job pricing, services offered, end user assistance).
 * <p>
 * In contrast, the
 * {@link PrinterMoreInfoManufacturer PrinterMoreInfoManufacturer} attribute is
 * used to find out more information about this general kind of printer rather
 * than this specific printer.
 * <p>
 * <b>IPP Compatibility:</b> The string form returned by {@code toString()}
 * gives the IPP uri value. The category name returned by {@code getName()}
 * gives the IPP attribute name.
