这段代码可以检测打印机是否缺纸吗

[未页]

private void isPapeout()
{
PrintServer myPrintServer = new PrintServer();
PrintQueue pringQueue;
try
{
pringQueue = myPrintServer.GetPrintQueue(printDocument1.PrinterSettings.PrinterName);
foreach (PrintSystemJobInfo job in pringQueue.GetPrintJobInfoCollection())
{
if (job.IsPaperOut==true)
{
MessageBox.Show("缺纸！");
}
else { MessageBox.Show("有纸！"); }
}
}
catch { MessageBox.Show("错误！"); }

}
