检查如果打印已成功完成
我正在C#中开发windowform应用程序。
在我的应用程序中,我编写了下面的代码以从本地机器获取所有图像并打印出来。
files = Directory.GetFiles(@"C:temp", "*.jpeg");
foreach (var i in files)
{
var objPrintDoc = new PrintDocument();
objPrintDoc.PrintPage += (obj, eve) =>
{
System.Drawing.Image img = System.Drawing.Image.FromFile(i);
Point loc = new Point(100, 100);
eve.Graphics.DrawImage(img, loc);
};
objPrintDoc.Print();
}
现在我想检查打印是否成功完成,然后我想删除我手动创建的临时文件夹来存储图像。
我尝试了下面的代码,但它不适合我。
PrintServer myPrintServer;
PrintQueueCollection myPrintQueues = myPrintServer.GetPrintQueues();
String printQueueNames = "My Print Queues:nn";
foreach (PrintQueue pq in myPrintQueues)
{
printQueueNames += "t" + pq.Name + "n";
}
请让我们知道我的问题,并做到需要。
谢谢,PRASHANT
这里是PrintSystemJobInfo.JobStatus的msdn描述
https://msdn.microsoft.com/en-us/library/system.printing.printsystemjobinfo.jobstatus(v=vs.110).aspx
我试了下面的代码,看到了打印状态。
private void brnPrint_Click(object sender, EventArgs e)
{
var files = Directory.GetFiles(@"D:Folder", "*.jpg");
foreach (var i in files)
{
var objPrintDoc = new PrintDocument();
objPrintDoc.PrintPage += (obj, eve) =>
{
Image img = Image.FromFile(i);
Point loc = new Point(100, 100);
eve.Graphics.DrawImage(img, loc);
};
objPrintDoc.Print();
PrintServer myPrintServer = new PrintServer(@"ComputerName");
PrintQueueCollection myPrintQueues = myPrintServer.GetPrintQueues();
try
{
foreach (PrintQueue pq in myPrintQueues)
{
pq.Refresh();
PrintJobInfoCollection pCollection = pq.GetPrintJobInfoCollection();
foreach (PrintSystemJobInfo job in pCollection)
{
listBox1.Items.Add(pq.Name);
SpotTroubleUsingJobAttributes(job);
}
}
}
catch (Exception)
{
//throw;
}
}
}
public void SpotTroubleUsingJobAttributes(PrintSystemJobInfo theJob)
{
if ((theJob.JobStatus & PrintJobStatus.Blocked) == PrintJobStatus.Blocked)
{
listBox1.Items.Add("The job is blocked.");
}
if (((theJob.JobStatus & PrintJobStatus.Completed) == PrintJobStatus.Completed)
||
((theJob.JobStatus & PrintJobStatus.Printed) == PrintJobStatus.Printed))
{
listBox1.Items.Add(
"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))
{
listBox1.Items.Add(
"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)
{
listBox1.Items.Add("The job has errored.");
}
if ((theJob.JobStatus & PrintJobStatus.Offline) == PrintJobStatus.Offline)
{
listBox1.Items.Add("The printer is offline. Have user put it online with printer front panel.");
}
if ((theJob.JobStatus & PrintJobStatus.PaperOut) == PrintJobStatus.PaperOut)
{
listBox1.Items.Add("The printer is out of paper of the size required by the job. Have user add paper.");
}
//if (((theJob.JobStatus & PrintJobStatus.Paused) == PrintJobStatus.Paused)

// //HandlePausedJob is defined in the complete example.
//}
if ((theJob.JobStatus & PrintJobStatus.Printing) == PrintJobStatus.Printing)
{
listBox1.Items.Add("The job is printing now.");
}
if ((theJob.JobStatus & PrintJobStatus.Spooling) == PrintJobStatus.Spooling)
{
listBox1.Items.Add("The job is spooling now.");
}
if ((theJob.JobStatus & PrintJobStatus.UserIntervention) == PrintJobStatus.UserIntervention)
{
listBox1.Items.Add("The printer needs human intervention.");
}
}
