这里面包含了一百多个JAVA源文件

The capabilities of a print job are called print job attributes. Examples of print job attributes include: Copies, OrientationRequested, and Destination. This example demonstrates how to retrieve the default value of a particular attribute. 
    Attribute attr = (Attribute)service.getDefaultAttributeValue(Destination.class);
    
    // attr == null if the attribute is not supported
    if (attr != null) {
        String attrName = attr.getName();
        // Get string representation of default value
        String attrValue = attr.toString();
        process(service, attrName, attrValue);
    }
