How to Use The LEADTOOLS Virtual Printer Driver

Take the following steps to create and run a program that prints using LEADTOOLS printer.

Start Visual Studio .NET.
Choose File->New->Project... from the menu.
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.
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.
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 "<LEADTOOLS_INSTALLDIR>\Bin\DotNet\Win32 " folder and select the following DLLs:
- Leadtools.dll
- Leadtools.Printer.dll

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 System.Drawing.Imaging
             Imports Leadtools
             Imports Leadtools.Printer

[C#]

             using System.Drawing.Imaging;
             using Leadtools;
             using Leadtools.Printer;

Declare the following private variable:

[Visual Basic]

             Private _printer as Printer

[C#]

             Printer _printer;

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.MonitorName = printerName
                  printerInfo.PortName = printerName
                  printerInfo.DriverName = printerName
                  printerInfo.ProductName = printerName
                  printerInfo.PrinterName = printerName
                  printerInfo.Password = printerPassword
                  printerInfo.RegistryKey = documentPrinterRegPath + printerName
                  printerInfo.RootDir = "C:\LEADTOOLS 17.5\Bin\Common\PrinterDriver\"
                  printerInfo.Url = "http://www.Leadtools.com"
                  printerInfo.PrinterExe = Application.ExecutablePath
                  Printer.Install(printerInfo)
                  _printer = New Printer(printerName)
                  AddHandler _printer.EmfEvent, AddressOf _printer_EmfEvent
                  AddHandler _printer.JobEvent, AddressOf _printer_JobEvent
                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.MonitorName = printerName;
                    printerInfo.PortName = printerName;
                    printerInfo.DriverName = printerName;
                    printerInfo.ProductName = printerName;
                    printerInfo.PrinterName = printerName;
                    printerInfo.Password = printerPassword;
                    printerInfo.RegistryKey = documentPrinterRegPath + printerName;
                    printerInfo.RootDir = @"C:\LEADTOOLS 17.5\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);
                }
             }

Add an event handler to the Emf event and code it as follows:

[Visual Basic]

               Private Sub _printer_EmfEvent(ByVal sender As Object, ByVal e As EmfEventArgs)
                  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);
             }

Add an event handler to the job info event and code it as follows:

[Visual Basic]

               Private Sub _printer_JobEvent(ByVal sender As Object, ByVal e As JobEventArgs)
                  Dim printerName As String = e.PrinterName
                  Dim jobID As Integer = e.JobID
                  If e.JobEventState = EventState.JobStart Then
                     MessageBox.Show(String.Format("Job {0} was started", jobID))
                  ElseIf e.JobEventState = EventState.JobEnd Then
                     MessageBox.Show(String.Format("Job {0} was Ended", jobID))
                  End If
               End Sub

[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));
                  }
               }

Build, and Run the program to test it.
