如何使用Windows服務打印PDF文件

Question

我試圖從我的Windows服務打印一個PDF文件。它沒有工作。後來我寫了一個控制檯應用程序來打印一個PDF文件。控制檯應用程序沒有工作！。Afterwords ii called that console從服務的應用程序打印PDF文件它didn'work。爲什麼「打印」不適用於Windows服務？以下是我試過的代碼片段

1.Used adobe reader: 
       PdfReportGeneration.Log logs = new PdfReportGeneration.Log(); 
       logs.writeLog("PrintDocument filepath:-" + filepath); 

       Process process = new Process(); 
       process.StartInfo.FileName = filepath; 
       process.StartInfo.UseShellExecute = true; 
       process.StartInfo.Verb = "printTo"; 
       process.StartInfo.Arguments = "HP LaserJet P1005"; 
       process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; 
       process.Start(); 
       process.WaitForInputIdle(); 
       process.Kill(); 

2. Used foxit reader/adobe reader both didnt work 
    string sArgs = " /t \"" + filepath + "\" \"" + "HP LaserJet P1005" + "\""; 
    System.Diagnostics.ProcessStartInfo startInfo = new ProcessStartInfo(); 
    startInfo.FileName = @"C:\Program Files\Foxit Software\Foxit Reader\Foxit Reader.exe"; 
    startInfo.Verb = "printTo"; 
    startInfo.Arguments = sArgs; 
    startInfo.CreateNoWindow = true; 
    startInfo.WindowStyle = ProcessWindowStyle.Hidden; 
    System.Diagnostics.Process proc = Process.Start(startInfo); 
    proc.WaitForExit(100000); // Wait a maximum of 10 sec for the process to finish 
    if (!proc.HasExited) 
    { 
     proc.Kill(); 
     proc.Dispose(); 
     // return false; 
    }*/ 

做了很多google bing yahoo ..沒用!!

服務通常由不同的帳戶運行。我會嘗試以用戶身份運行服務。可能是系統用戶沒有映射該打印機的問題。服務安裝類看起來是這樣的：

[RunInstaller(true)] 
public class ServiceInstall : Installer 
{ 
    public ServiceInstall() 
    { 
     ServiceInstaller serviceInstaller = new ServiceInstaller(); 
     ServiceProcessInstaller serviceProcessInstaller = new ServiceProcessInstaller(); 

     serviceProcessInstaller.Account = ServiceAccount.User; 
     serviceProcessInstaller.Username = "User"; 
     serviceProcessInstaller.Password = "Password"; 

     serviceInstaller.DisplayName = "Some Service"; 
     serviceInstaller.StartType = ServiceStartMode.Automatic; 
     serviceInstaller.ServiceName = "Some Service"; 

     this.Installers.Add(serviceProcessInstaller); 
     this.Installers.Add(serviceInstaller); 
    } 
}
