  1. PrinterServer:在打印服务器上管理打印队列。
     1 // Create a PrintServer 2 // "theServer" must be a print server to which the user has full print access. 3 PrintServer myPrintServer = new PrintServer(@"\\theServer"); 4  5 // List the print server‘s queues 6 PrintQueueCollection myPrintQueues = myPrintServer.GetPrintQueues(); 7 String printQueueNames = "My Print Queues:\n\n"; 8 foreach (PrintQueue pq in myPrintQueues) 9 {10     printQueueNames += "\t" + pq.Name + "\n";11 }12 Console.WriteLine(printQueueNames);13 Console.WriteLine("\nPress Return to continue.");14 Console.ReadLine();

  2. PrintQueue:管理打印机与打印作业
  3. PrintSystemJobInfo:详细定义打印作业
  4. PrintJobStatus:指定打印队列中打印作业的当前状态。
  5. PrintQueueStatus:指定打印队列或其打印机的状态。
  6. PrintQueue.QueueStatus:获取用于表示打印机状态的值。 这些状态包括“正在预热”、“正在初始化”、“正在打印”等。
