Multi Printer Support Program in ASP.Net C#

I have made this program for one of my client,who want to give one print command to print a document on different printers in different location simultaneously which are connected to server. RPC should be activated on server to use this program.

string FilePath = strPathToUpload + "\\" + fUpload.FileName;
if (strExt.ToUpper().Equals("TXT"))
{
    fUpload.SaveAs(strPathToUpload + "\\" + fUpload.FileName);
    Printer1(FilePath);
    Printer2(FilePath);
}
else
{
    lblMessage.Text="Invalid File Seleected";
}
public void Printer1(string FilePath)
{
    sr = new StreamReader(FilePath);
    f = new Font("Courier New", 14);
    PrintDocument pd = new PrintDocument();
    pd.PrintPage += new PrintPageEventHandler(pqr);
    pd.PrinterSettings.PrinterName = "PDF995";
    if (pd.PrinterSettings.IsValid)
    {
       pd.Print();
    }
    sr.Close();
}
public void Printer2(string FilePath)
{
    sr = new StreamReader(FilePath);
    f = new Font("Courier New", 14);
    PrintDocument pd2 = new PrintDocument();
    pd2.PrintPage += new PrintPageEventHandler(pqr);
    pd2.PrinterSettings.PrinterName = "Real PDF Printer";
    if (pd2.PrinterSettings.IsValid)
    {
        pd2.Print();
    }
    sr.Close();
}
void pqr(object o, PrintPageEventArgs e)
{
    float lpp = e.MarginBounds.Height / f.GetHeight(e.Graphics);
    int c = 0;
    String s = null;
    while (c < lpp && ((s = sr.ReadLine()) != null))
    {
       float y = e.MarginBounds.Top + (c * f.GetHeight(e.Graphics));
       e.Graphics.DrawString(s, f, Brushes.Black, e.MarginBounds.Left, y);
       c++;
    }
    if (s != null)
    e.HasMorePages = true;
   else
     e.HasMorePages = false;
}
