How to set the printer in C# for a web page?

[Brian Connelly]

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. Any help would be greatly appreciated. Sample codes are below.

Windows Form:

  public partial class Form1 : Form
  {
    private const string TEMPLATE_DIRECTORY = @"C:\Program Files\Brother bPAC3 SDK\Templates\";    // 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();
    }
 
    private void btnPrint_Click(object sender, EventArgs e)
    {
      try
      {
        string templatePath = TEMPLATE_DIRECTORY;
        templatePath += TEMPLATE_SIMPLE;
        MessageBox.Show("Template Directory and File Set");
        bpac.DocumentClass doc = new DocumentClass();
        doc.Open(templatePath);
        MessageBox.Show("Doc Path Opened");
        doc.GetObject("objCompany").Text = "Test Company";
        doc.GetObject("objName").Text = "Test Name";
        MessageBox.Show("Values Add to Template Objects");
        doc.StartPrint("", PrintOptionConstants.bpoDefault);
        MessageBox.Show("Print Started");
        doc.PrintOut(1, PrintOptionConstants.bpoDefault);
        MessageBox.Show("PrintOut");
        doc.EndPrint();
        MessageBox.Show("Print Ended");
        doc.Close();
      }
      catch (Exception ex)
      {
        MessageBox.Show("Print Failed: " + ex);
      }
 
    }
  }
}

ASPX Page:

protected void btnPrint_Click(object sender, EventArgs e)
  {
    Type clientType = this.GetType();
    ClientScriptManager clientManager = Page.ClientScript;
 
    string theTemplate = Template_File_Path.ToString();
    if (ddlTemplate.SelectedIndex == 0)
    {
      theTemplate += TEMPLATE_SIMPLE;
    }
    else if (ddlTemplate.SelectedIndex == 1)
    {
      theTemplate += TEMPLATE_FRAME;
    }
    //try
    //{
      bpac.DocumentClass doc = new DocumentClass();
      clientManager.RegisterStartupScript(clientType, "Check1", "<Script>alert('" + theTemplate + "');</script>", false);
      clientManager.RegisterStartupScript(clientType, "Check2", "<Script>alert('" + doc.Open(theTemplate) + "');</script>", false);
      if (doc.Open(theTemplate) != false)
      {
        doc.GetObject("objCompany").Text = "McGladrey LLP Test";
        doc.GetObject("objName").Text = txtCompany.Text;
            if(doc.Printer.IsPrinterOnline(Printer_Device))
{
clientManager.RegisterStartupScript(clientType, "Printer Check", "<Script>alert('Yes Printer is Online');</script>", false);
}
else
{
clientManager.RegisterStartupScript(clientType, "Printer Check", "<Script>alert('No Printer is not Online');</script>", false);
}
 
 
        doc.SetPrinter(Printer_Device, true);
       clientManager.RegisterStartupScript(clientType, "Check3", "<Script>alert('" + doc.SetPrinter(Printer_Device, true) + "');</script>", 
 
false);
          doc.StartPrint("", PrintOptionConstants.bpoDefault);
    doc.PrintOut(1, PrintOptionConstants.bpoDefault);
        bool res= doc.PrintOut(1, PrintOptionConstants.bpoDefault);
 
    clientManager.RegisterStartupScript(clientType, "Check12", "<Script>alert('" + res + "');</script>", false);
        doc.EndPrint();
        doc.Close();
 
          clientManager.RegisterStartupScript(clientType, "Print Error1", "<Script>alert('The Print Succeeded');</script>", false);
      }
      else
      {
 
 
        clientManager.RegisterStartupScript(clientType, "Print Error", "<Script>alert('The Print Failed');</script>", false);
      }
 
  }
}
