c# 获取打印机 打印任务 文件名 、状态

[lanyubaic]

有什么办法判断 某个打印任务是否完成

[冬冬冬冬冬冬冬冬冬冬]

使用.net类库里面的print即可

[漫步前行的蜗牛]

获取状态： par:打印机名称

  private PrintQueue GetPrintQueue(string PrinterName)
        {
            LocalPrintServer pr = new LocalPrintServer();
            pr.Refresh();
            EnumeratedPrintQueueTypes[] enumerationFlags = {EnumeratedPrintQueueTypes.Local,
                                                            EnumeratedPrintQueueTypes.Connections,
                                                           };
            foreach (PrintQueue pq in pr.GetPrintQueues(enumerationFlags))
            {
                if (pq.Name == PrinterName)
                {
                    return pq;
                }
            }
            return null;
        }

判断状态：

 if (printQueue.IsBusy)
                    printStateText = "打印机正忙";
                else if (printQueue.IsDoorOpened)
                    printStateText = "打印机门被打开";
                else if (printQueue.IsInError)
                    printStateText = "打印机出错";
                else if (printQueue.IsInitializing)
                    printStateText = "打印机正在初始化";
                else if (printQueue.IsIOActive)
                    printStateText = "打印机正在与打印服务器交换数据";
                else if (printQueue.IsManualFeedRequired)
                    printStateText = "打印机出错";
                else if (printQueue.IsNotAvailable)
                    printStateText = "打印机状态信息不可用";
                else if (printQueue.IsTonerLow)
                    printStateText = "打印机墨粉用完";
                else if (printQueue.IsOffline)
                    printStateText = "打印机脱机";
                else if (printQueue.IsOutOfMemory)
                    printStateText = "打印机无可用内存";
                else if (printQueue.IsOutputBinFull)
                    printStateText = "打印机输出纸盒已满";
                else if (printQueue.IsPaperJammed)
                    printStateText = "打印机卡纸";
                else if (printQueue.IsOutOfPaper)
                    printStateText = "打印机中没有或已用完当前打印作业所需的纸张类型";
                else if (printQueue.QueueStatus == PrintQueueStatus.PaperProblem)
                    printStateText = "打印机中的纸张导致未指定的错误情况";
                else if (printQueue.IsPaused)
                    printStateText = "打印队列已暂停";
                else if (printQueue.IsPendingDeletion)
                    printStateText = "打印队列正在删除打印作业";
                else if (printQueue.IsPrinting)
                    printStateText = "设备正在打印";
                else if (printQueue.IsProcessing)
                    printStateText = "设备正在执行某种工作，如果此设备是集打印机、传真机和扫描仪于一体的多功能设备，则不需要打印.";
                else if (printQueue.IsServerUnknown)
                    printStateText = "打印机处于错误状态";
                //else if (printQueue.IsWarmingUp)
                //     printStateText = "打印机正在预热";

PrintQueue 是引用 哪个！

[lanyubaic]

PrintQueue 是引用system.printing.dll

[lanyubaic]

printStateText 是什么意思，我换成 MessageBox.Show("打印机出错"); 结果 这些条件判断都不在里面。

[lanyubaic]

pint 类吗？不好意思，我是初学者， .net 类库，是在 msdn 里面找吗！

[姑娘出来我爬山坡]

帮顶。。 我也需要
