唉，还是摸索懂了。我自己回答吧……private PrintQueue getQueue(String PrinterName)
        {
            PrintServer myPrintServer = new PrintServer(PrinterName);
            PrintQueueCollection myPrintQueues = myPrintServer.GetPrintQueues();            foreach (PrintQueue printer in myPrintQueues)
            {
                if (printer.Name == PrinterName) return printer;
            }
            return null;
        }
上诉方法获得一个PrintQueue后，用下述方法判断：PrintQueue myPrintQueue = getQueue(printDocument1.PrinterSettings.PrinterName);
myPrintQueue.Refresh(); 
                if (myPrintQueue.NumberOfJobs <1)
                {//队列中文档数大于1则不予打印
                    printDocument1.Print();
                }
