Trying to print a file which is .pmf file in c# application

Question

I am trying to print a file which is .pmf file using print button which should display printer properties as well but after executing the below code I am getting a blank page as a result. Please, anybody can tell me what is wrong with the code shown below. I have added PrintDialog control from Toolbox to the Form in Visual Studio.

private void btn_Print_Click(object sender, EventArgs e)

{

PrintDialog printDlg = new PrintDialog();

PrintDocument printDoc = new PrintDocument();

printDoc.DocumentName = "D:\\Project_Folder\\Soil_Units_PMF\\pmf\\KUM1_1G1b_Soilunits_Profile.pmf";

printDlg.Document = printDoc;

printDlg.AllowSelection = true;

printDlg.AllowSomePages = true;

//Call ShowDialog

if (printDlg.ShowDialog() == DialogResult.OK)

{

printDoc.Print();

}

else

{

return;

}

}
