selection = ServiceUI.printDialog( null, 100, 100, services, service, null, attrs);
job = selection.createPrintJob();
doc = new SimpleDoc(table, flavor, attr);//构造具有指定打印数据、doc flavor 和 doc 属性集的 SimpleDoc

for (int i = 0; i < services.length; i++)
{
System.out.println(services[i].getName());
}
try {
job.print(doc, attrs);
} catch (PrintException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}


这是自动报出的错==
