How to Use The LEADTOOLS Virtual Printer Driver
Take the following steps to create and run a program that print using LEADTOOLS printer.
  1. Start Visual Studio .NET.
  2. Choose File->New->Project… from the menu.
  3. In the New Project dialog box, choose either "Visual C# Projects" or "Visual Basic Projects" in the Projects Type List, and choose "Windows Application " in the Templates List.
  4. Type the project name as " PRINTER DRIVER " in the Project Name field, and then choose OK. If desired, type a new location for your project or select a directory using the Browse button, and then choose OK.
  5. In the "Solution Explorer" window, right-click on the "References" folder, and select "Add Reference…" from the context menu. In the "Add Reference" dialog box, select the ".NET" tab and browse to Leadtools For .NET "\LEAD Technologies\LEADTOOLS 16.5\Bin\DotNet\Win32 " folder and select the following DLLs:
    • Leadtools.dll
    • Leadtools.Forms.DocumentWriters.dll
    • Leadtools.Codecs.dll
    • Leadtools.WinForms.CommonDialogs.File.dll
    • Leadtools.Printer.dll
  6. Switch to Form1 code view (right-click Form1 in the solution explorer then select View Code ) and add the following lines at the beginning of the file:

    [Visual Basic] 

    
Imports Leadtools
Imports Leadtools.Printer
Imports Leadtools.Codecs
import Leadtools.Forms.DocumentWriters
Imports Leadtools.WinForms
    [C#] 
    
using Leadtools;
using Leadtools.Printer;
using Leadtools.Codecs;
using Leadtools.Forms.DocumentWriters;
using Leadtools.WinForms.CommonDialogs.File;
  7. Declare the following private variable:

    [Visual Basic] 

    
Private WithEvents _printer as Printer
    [C#] 
    
Printer _printer;
  8. Add an event handler to the Form1 Load event and code it as follows:

    [Visual Basic] 

    
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
   Try
     Dim printerName as string="LEADTOOLS Printer"
     Dim printerPassword as string="1234"
     Dim documentPrinterRegPath As String = "SOFTWARE\\LEAD Technologies, Inc.\\Printer\\"
     Dim printerInfo As New PrinterInfo()
     printerInfo.DriverName = printerName
     printerInfo.ProductName = printerName
     printerInfo.PrinterName = printerName
     printerInfo.Password = printerPassword
     printerInfo.RegistryKey = documentPrinterRegPath + printerName
     printerInfo.RootDir = "C:\Program Files (x86)\LEAD Technologies\Bin\Common\PrinterDriver\"
     printerInfo.Url = "http://www.Leadtools.com"
     printerInfo.PrinterExe = Application.ExecutablePath
     Printer.Install(printerInfo)
   Catch ex As Exception
      MessageBox.Show(ex.Message)
   End Try
End Sub
    [C#] 
    
private void Form1_Load(object sender, System.EventArgs e)
{
   try
   {
       string printerName="LEADTOOLS Printer";
       string printerPassword="1234";
       string documentPrinterRegPath = @"SOFTWARE\LEAD Technologies, Inc.\Printer\";
       PrinterInfo printerInfo = new PrinterInfo();
       printerInfo.DriverName = printerName;
       printerInfo.ProductName = printerName;
       printerInfo.PrinterName = printerName;
       printerInfo.Password = printerPassword;
       printerInfo.RegistryKey = documentPrinterRegPath + printerName;
       printerInfo.RootDir = @"C:\Program Files (x86)\LEAD Technologies\LEADTOOLS 16.5\Bin\Common\PrinterDriver\";
       printerInfo.Url = "http://www.Leadtools.com";
       printerInfo.PrinterExe = Application.ExecutablePath;
       Printer.Install(printerInfo);
       _printer=new Printer(printerName);
       _printer.EmfEvent += new EventHandler<EmfEventArgs>(_printer_EmfEvent);
       _printer.JobEvent += new EventHandler<JobEventArgs>(_printer_JobEvent);
   }
   catch (Exception ex)
   {
      MessageBox.Show(this, ex.Message);
   }
}
  9. Add an event handler to the Emf event and code it as follows:

    [Visual Basic] 

    
Private Sub printerTest_EmfEvent(ByVal sender As Object, ByVal e As EmfEventArgs) Handles printerTest.EmfEvent
   System.IO.File.WriteAllBytes("c:\LEADTOOLS_IMAGE1.emf", e.Stream.ToArray())
   Dim metaFile As New Metafile(e.Stream)
End Sub
    [C#] 
    
void _printer_EmfEvent(object sender, EmfEventArgs e)
{
  System.IO.File.WriteAllBytes(@"c:\1.emf", e.Stream.ToArray());
  Metafile metaFile = new Metafile(e.Stream);
}
  10. Add an event handler to the job info event and code it as follows:

    [Visual Basic] [C#] 

    
void _printer_JobEvent(object sender, JobEventArgs e)
{
    string printerName = e.PrinterName;
    int jobID = e.JobID;
    
    if (e.JobEventState == EventState.JobStart)
    {
       MessageBox.Show(string.format("Job {0} was started",jobID));
    }
    else if (e.JobEventState == EventState.JobEnd)
    {
       MessageBox.Show(string.format("Job {0} was Ended",jobID));
    }
 }
  11. Build, and Run the program to test it.
