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 click OK. If desired, type a new location for your project or select a directory using the Browse button, and then click 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 System.Drawing.Printing
            Imports Leadtools
            Imports Leadtools.Printer

[C#]


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

Declare the following private variable: [Visual Basic]


            Private _printer as Printer

[C#]


            private 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 installedPrinters As List(Of String) = New List(Of String)()
                 For Each printer As String In PrinterSettings.InstalledPrinters
                    installedPrinters.Add(printer)
                 Next
                 If Not installedPrinters.Contains(printerName) Then
                    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 18\Bin\Common\PrinterDriver\"
                    printerInfo.Url = "http://www.Leadtools.com"
                    printerInfo.PrinterExe = Application.ExecutablePath
                    Printer.Install(printerInfo)
                 End If
                 _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";
                   List<string> installedPrinters = new List<string>();
                   foreach (string printer in PrinterSettings.InstalledPrinters)
                      installedPrinters.Add(printer);
                   if (!installedPrinters.Contains(printerName))
                   {
                      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 18\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.
