Try SetDefaultPrinter Windows API function

   using System.Runtime.InteropServices;

   ...

   [DllImport("winspool.drv", 
              CharSet = CharSet.Auto, 
              SetLastError = true)]
   [return: MarshalAs(UnmanagedType.Bool)]
   public static extern Boolean SetDefaultPrinter(String name);

   ...

   SetDefaultPrinter(PrinterName);

Answer 2

Right click on the project in Solution Explorer, choose Properties. Select the Settings tab, add PrinterName setting.

In the code use the setting:

string PrinterName
{
    get { return (string)Properties.Settings.Default["PrinterName"]; }
    set 
    { 
        Properties.Settings.Default["PrinterName"] = value;
        Properties.Settings.Default.Save(); 
    }
}

private void print_Click(object sender, EventArgs e)
{
    PrintDialog pd = new PrintDialog();
    if (PrinterName != "")
        pd.PrinterSettings.PrinterName = PrinterName;
    if (pd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
    {
        // Print

        PrinterName = pd.PrinterSettings.PrinterName;
    }
}
