Printer Driver Files To Be Included With Your Application

After an application is developed and ready to redistribute, create a setup.exe that includes all of the necessary files.

This topic summarizes which files to include on your distribution diskettes to support the LEADTOOLS Virtual Printer functions on WIN32 and x64 systems.

Note: You may not copy or redistribute any of the following files without obtaining the proper license. In some cases, the license is included with your initial purchase of LEADTOOLS. In other cases, you must obtain a license from a third party or enter into a royalty agreement with LEAD to obtain the proper license.

General Notes:

• The \Redist\ subdirectories contain copies of these files.
• Leadtools.Printer.dll is required for all applications.

Environment-Specific notes:

• 32-bit Operating Systems: Unless otherwise noted, all 32-bit files should be deployed to the System32 folder as shared files.
• 64-bit Operating Systems: Unless otherwise noted, all 32-bit files should be deployed to the SysWow64 folder and all 64-bit files should be deployed to the System32 folder as shared files.
• XP / Server 2003: If running within a service on an XP or Server 2003 machine you may run into an issue where the printer installs but does not receive the events. This is a result of the default DCOM authentication settings. To correct this, go to Start -> Run and enter "dcomcnfg". Then right click on Component Services -> Computers -> My Computer and select **properties. On the Default Properties tab select "None" for the Default Authentication Level.

Destination directory structure specification:

Use the Install method to install the LEADTOOLS Virtual Printer Module. Pass the structure PrinterInfo to this function. The installation path specified in the RootDir member of the PrinterInfo structure is the root folder in which the LEADTOOLS Virtual Printer is installed. This folder should contain two sub-folders:

• -\Bin - This folder should contain the LeadtoolsPrinter.exe executable file.
• -\Spool - Stores temporary files generated while printing(Create an empty folder if it does not already exist).

Note: All users of the printer must have access to the folder specified in the RootDir member.

Printer Driver INF installation for Windows Vista and later:

• Use the following method to install the LEADTOOLS Virtual Printer Driver INF:

[DllImport("user32.dll")] 
static extern IntPtr GetDesktopWindow(); 
                       
[DllImport("Winspool.drv")] 
static extern Int32 UploadPrinterDriverPackage(string pszServer, string pszInfPath, string pszEnvironment, uint dwFlags, IntPtr hwnd, StringBuilder pszDestInfPath, out ulong pcchDestInfPath); 
                       
[DllImport("Winspool.drv")] 
static extern Int32 InstallPrinterDriverFromPackage(string pszServer, string pszInfPath, string pszDriverName, string pszEnvironment, uint dwFlags); 
                       
static Int32 InstallDriverPackage(string infPath, string environment) 
{ 
   IntPtr handle = GetDesktopWindow(); 
   StringBuilder targetPath = new StringBuilder(512); 
   ulong targetPathLength = 512; 
   Int32 result = UploadPrinterDriverPackage(null, infPath, environment, 2, handle, targetPath, out targetPathLength); 
   if(result == 0) 
      result = InstallPrinterDriverFromPackage(null, targetPath.ToString(), "LEADTOOLS VIRTUAL PRINTER", environment, 0); 
                       
   return result; 
} 

• Install the 64-bit driver package by calling:

InstallDriverPackage(Redist\\DriverPackageX64\\LeadtoolsVirtualPrinter.INF, "Windows x64");

• Install the 32-bit driver package by calling:

InstallDriverPackage(Redist\\DriverPackageX86\\LeadtoolsVirtualPrinter.INF, "Windows NT x86");

Note: For Network printing, it is possible to install both packages (x86 and x64) on the Server machine in order to support both types of client machines.
