 * consumption. Features outside the scope of the Print Service API can be
 * accessed from this 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).

 * 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.
