C Sharp :: How To Set Printer For A Web Page

I have a test web page and a windows form which call a printer and sends a print job to a printer that is on the network. I have been able to successfully do this from the windows form, however, I can figure out how to do it from an aspx page to the server's default printer. Sample codes are below.

Windows Form:
  public partial class Form1 : Form   {
    private const string TEMPLATE_DIRECTORY = @"C:Program FilesBrother bPAC3 SDKTemplates";    // Template file path
    private const string TEMPLATE_SIMPLE = "NamePlate1.LBX";    // Template file name
    private const string TEMPLATE_FRAME = "NamePlate2.LBX";        // Template file name
    public Form1() {
      InitializeComponent();
