如何使用c#检查打印作业状态

本文关键字：打印 作业状态 检查 何使用 | 更新日期: 2023-09-27 17:49:26

我正在从c#应用程序中执行命令行应用程序来打印PDF文件。现在我想知道这份文件什么时候打印出来。我希望能有什么我可以订阅的活动，并处理它。但是我找不到它。

所以现在我要求助于轮询。检查prinintersystemjobinfo对象的JobStatus。但在我的情况下，这要么给我JobStatus = None或JobStatus = Printing。

PrinterSystemJobInfo.JobStatus

有人能告诉我如何使用c#可靠地检查打印作业状态吗?

如何使用c#检查打印作业状态

这是微软帮助和支持网站上的一篇好文章，涉及如何使用Visual c# . net向打印机发送原始数据。

好吧，你可以在这个例子中检查sendbytestopprinter方法;它将返回打印结果

也可以使用以下代码:

public enum PrintJobStatus
// Check for possible trouble states of a print job using the flags of the JobStatus property
internal static void SpotTroubleUsingJobAttributes(PrintSystemJobInfo theJob)
{
if ((theJob.JobStatus & PrintJobStatus.Blocked) == PrintJobStatus.Blocked)
{
Console.WriteLine("The job is blocked.");
}
if (((theJob.JobStatus & PrintJobStatus.Completed) == PrintJobStatus.Completed)
||
((theJob.JobStatus & PrintJobStatus.Printed) == PrintJobStatus.Printed))
{
Console.WriteLine("The job has finished. Have user recheck all output bins and be sure the correct printer is being checked.");
}
if (((theJob.JobStatus & PrintJobStatus.Deleted) == PrintJobStatus.Deleted)
||
((theJob.JobStatus & PrintJobStatus.Deleting) == PrintJobStatus.Deleting))
{
Console.WriteLine("The user or someone with administration rights to the queue has deleted the job. It must be resubmitted.");
}
if ((theJob.JobStatus & PrintJobStatus.Error) == PrintJobStatus.Error)
{
Console.WriteLine("The job has errored.");
}
if ((theJob.JobStatus & PrintJobStatus.Offline) == PrintJobStatus.Offline)
{
Console.WriteLine("The printer is offline. Have user put it online with printer front panel.");
}
if ((theJob.JobStatus & PrintJobStatus.PaperOut) == PrintJobStatus.PaperOut)
{
Console.WriteLine("The printer is out of paper of the size required by the job. Have user add paper.");
}
if (((theJob.JobStatus & PrintJobStatus.Paused) == PrintJobStatus.Paused)
||
((theJob.HostingPrintQueue.QueueStatus & PrintQueueStatus.Paused) == PrintQueueStatus.Paused))
{
HandlePausedJob(theJob);
//HandlePausedJob is defined in the complete example.
}
if ((theJob.JobStatus & PrintJobStatus.Printing) == PrintJobStatus.Printing)
{
Console.WriteLine("The job is printing now.");
}
if ((theJob.JobStatus & PrintJobStatus.Spooling) == PrintJobStatus.Spooling)
{
Console.WriteLine("The job is spooling now.");
}
if ((theJob.JobStatus & PrintJobStatus.UserIntervention) == PrintJobStatus.UserIntervention)
{
Console.WriteLine("The printer needs human intervention.");
}
}//end SpotTroubleUsingJobAttributes

但是提供的第一个解决方案更可靠
