Take the following steps to create and run a program that installs a LEADTOOLS Network Client Printer.
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:
Add a reference to System.Windows.Forms from the .NET tab of the Add References dialog.
Add the following code to the beginning of the file:
Imports System.Windows.Forms
Imports Leadtools.Printer.Client.Interfaces
using System.Windows.Forms
using Leadtools.Printer.Client.Installer;
Implement the IVirtualPrinterClient interface using the following code:
Public Class MyVirtualPrinterClient
Implements IVirtualPrinterClient
public class MyVirtualPrinterClient : IVirtualPrinterClient
The created class needs to implement the three IVirtualPrinterClient methods. Open MyVirtualPrinterClient.cs and implement the following methods:
bool IVirtualPrinterClient.Startup(string virtualPrinterName, byte[] initialData) - This function will get called by the Virtual Printer Driver at startup
virtualPrinterName: printer name
initialData: will hold the initialization data sent from server.
Implement the Startup with the following code:
Private Function Startup(ByVal virtualPrinterName As String, ByVal initialData As Byte()) As Boolean Implements IVirtualPrinterClient.Startup
MessageBox.Show("Job received from " & virtualPrinterName & "printer")
Return True
End Function
bool IVirtualPrinterClient.Startup(string virtualPrinterName, byte[] initialData)
{
MessageBox.Show("Job received from " + virtualPrinterName + "printer");
return true;
}
bool IVirtualPrinterClient.PrintJob(PrintJobData printJobData) - This function will be called as the print job is received by the driver.
printJobData: contains printer data for this job
Implement the PrintJob method using the following code:
Private Function PrintJob(ByVal printJobData As PrintJobData) As Boolean Implements IVirtualPrinterClient.PrintJob
MessageBox.Show("Job data Ip Address = " & printJobData. IpAddress & " Job ID = " & printJobData.JobID)
'the UserData will be sent to the server machine
'this data can be any user specified data format
printJobData.UserData = New Byte() { CByte("H"c), CByte("E"c), CByte("L"c), CByte("L"c), CByte("O"c) }
Return True
End Function
bool IVirtualPrinterClient.PrintJob(PrintJobData printJobData)
{
MessageBox.Show("Job data Ip Address = " + printJobData. IpAddress + " Job ID = " + printJobData.JobID);
//the UserData will be sent to the server machine
//this data can be any user specified data format
printJobData.UserData = new byte[] { (byte)'H', (byte)'E', (byte)'L', (byte)'L', (byte)'O' };
return true;
}
void IVirtualPrinterClient.Shutdown(string virtualPrinterName) - This function will be called as a shutdown event
virtualPrinterName: Printer name
Implement the Shutdown method using the following code:
Private Sub Shutdown(ByVal virtualPrinterName As String) Implements IVirtualPrinterClient.Shutdown
MessageBox.Show("Shutdown received for " & virtualPrinterName & " printer")
End Sub
void IVirtualPrinterClient.Shutdown(string virtualPrinterName)
{
MessageBox.Show("Shutdown received for " + virtualPrinterName + " printer");
}
