1. PrinterServer:在列印伺服器上管理列印佇列。

    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:管理印表機與列印工作
3. PrintSystemJobInfo:詳細定義列印工作
4. PrintJobStatus:指定列印佇列中列印工作的目前狀態。
5. PrintQueueStatus:指定列印佇列或其印表機的狀態。
6. PrintQueue.QueueStatus:擷取用於表示印表機狀態的值。 這些狀態包括“正在預熱”、“正在初始化”、“正在列印”等。
