How to print the files without affecting the default printer setting?

Question

I have checked with the "Let \Windows manage my default Printer" checkbox in Printer & Scanners setting, if I used the below code for printing my document, it is changing the default printer from Printer & Scanners setting.

public void Print(string FileName, int pintprintqty)
{
if (string.IsNullOrWhiteSpace(FileName)) return; // Prevents execution of below statements if filename is not selected.
PrintDocument pd = new PrintDocument();
//Disable the printing document pop-up dialog shown during printing.
PrintController printController = new StandardPrintController();
pd.PrintController = printController;
pd.PrinterSettings.PrinterName = cmbLabelPrinter.Text.ToString();
pd.PrinterSettings.Copies = Convert.ToInt16(pintprintqty);
pd.DefaultPageSettings.Landscape = false;
pd.DefaultPageSettings.Margins = new Margins(0, 0, 0, 0);
pd.PrinterSettings.DefaultPageSettings.Margins = new Margins(0, 0, 0, 0);
pd.PrintPage += (sndr, args) =>
{
System.Drawing.Image i = System.Drawing.Image.FromFile(FileName);
//Adjust the size of the image to the page to print the full image without loosing any part of the image.
System.Drawing.Rectangle m = args.MarginBounds;
//Logic below maintains Aspect Ratio.
if ((double)i.Width / (double)i.Height > (double)m.Width / (double)m.Height) // image is wider
{
m.Height = (int)((double)i.Height / (double)i.Width * (double)m.Width);
}
else
{
m.Width = (int)((double)i.Width / (double)i.Height * (double)m.Height);
}
//Calculating optimal orientation.
pd.DefaultPageSettings.Landscape = m.Width > m.Height;
pd.DefaultPageSettings.Landscape = false; //New
args.Graphics.DrawImage(i, m);
};
pd.Print();
}
