How to use the LEADTOOLS Network Virtual Printer

Take the following steps to create and run a program that print using LEADTOOLS Network printer on the server machine.

Make sure you have IIS installed on the machine correctly. And make sure the LEADTOOLS virtual printer web service is configured correctly.
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 SERVER" 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 the Leadtools For .NET "<LEADTOOLS_INSTALLDIR>\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

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
             Imports Leadtools.Codecs
             Imports Leadtools.Forms.DocumentWriters
             Imports Leadtools.WinForms
             Imports System.Text
             Imports System.Diagnostics

[C#]


             using System.Drawing.Imaging;
             using Leadtools;
             using Leadtools.Printer;
             using Leadtools.Codecs;
             using Leadtools.Forms.DocumentWriters;
             using Leadtools.WinForms.CommonDialogs.File;
             using System.Text;
             using System.Diagnostics;

Declare the following private variable: [Visual Basic]


             Private WithEvents _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 Object, ByVal e As System.EventArgs)
                      Try
                             Dim printerName As String = "LEADTOOLS Printer"
                             If (Not Printer.IsLeadtoolsPrinter(printerName)) Then
                                Dim printerPassword As String = "1234"
                                Dim documentPrinterRegPath As String = "SOFTWARE\LEAD Technologies, Inc.\Printer\"
                                Dim printerInfo As PrinterInfo = New PrinterInfo()
                                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)
                             _printer.EnableNetworkPrinting = True
                             AddHandler _printer.EmfEvent, AddressOf Of EmfEventArgs
                             AddHandler _printer.JobEvent, AddressOf Of JobEventArgs
                      Catch ex As Exception
                             MessageBox.Show(Me, ex.Message)
                      End Try
               End Sub

[C#]


                  private void Form1_Load(object sender, System.EventArgs e)
                  {
                     try
                     {
                        string printerName = "LEADTOOLS Printer";
                        if (!Printer.IsLeadtoolsPrinter(printerName))
                        {
                           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:\LEADTOOLS 18\Bin\Common\PrinterDriver\";
                           printerInfo.Url = "http://www.Leadtools.com";
                           printerInfo.PrinterExe = Application.ExecutablePath;
                           Printer.Install(printerInfo);
                        }
                        _printer = new Printer(printerName);
                        _printer.EnableNetworkPrinting = true;
                        _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 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:\LEADTOOLS_IMAGE1.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
                  Try
                     'Data is string, the user specifies the data to sent from the client machine
                     'check user demo for more info
                     Dim enc As Encoding = Encoding.ASCII
                     Dim strData As String = enc.GetString(_printer.RemoteData.UserData)
                     MessageBox.Show(String.Format("Job {0} was started with remote data " & strData, jobID))
                  Catch ex As Exception
                     MessageBox.Show(ex.Message)
                     Throw
                  End Try
               Else If e.JobEventState = EventState.JobEnd Then
                  MessageBox.Show(String.Format("Job {0} was Ended", jobID))
                  Process.Start("mspaint", "c:\LEADTOOLS_IMAGE1.emf")
               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)
               {
                  try
                  {
                     // Data is string, the user specifies the data to sent from the client machine
                     // check user demo for more info
                     Encoding enc = Encoding.ASCII;
                     String strData = enc.GetString(_printer.RemoteData.UserData);
                     MessageBox.Show(string.Format("Job {0} was started with remote data " + strData, jobID));
                  }
                  catch (Exception ex)
                  {
                     MessageBox.Show(ex.Message);
                     throw;
                  }
               }
               else if (e.JobEventState == EventState.JobEnd)
               {
                  MessageBox.Show(string.Format("Job 0 was Ended", jobID));
                  Process.Start("mspaint", @"c:\LEADTOOLS_IMAGE1.emf");
               }
            }

Note: when the job event is received, the _printer.RemoteDate will return the data sent from the remote machine, this data will be available until demo receives EventState.JobEnd _printer.RemoteDate will contain row data, this raw data will be specified by the user.

Build, and Run the program to test it.
Make sure to share the new printer after installing it.
