Cómo: Diagnosticar trabajos de impresión problemáticos

2025-05-07

Los administradores de red suelen recibir quejas de los usuarios acerca de los trabajos de impresión que no se imprimen o se imprimen lentamente. El amplio conjunto de propiedades del trabajo de impresión expuestas en las API de Microsoft .NET Framework proporciona un medio para realizar un diagnóstico remoto rápido de trabajos de impresión.

Ejemplo

Los pasos principales para crear este tipo de utilidad son los siguientes.

Identifique el trabajo de impresión del que se queja el usuario. Los usuarios a menudo no pueden hacerlo con precisión. Es posible que no conozcan los nombres de los servidores de impresión o impresoras. Pueden describir la ubicación de la impresora utilizando una terminología diferente a la empleada en la configuración de su Location propiedad. Por lo tanto, es conveniente generar una lista de los trabajos enviados actualmente por el usuario. Si hay más de uno, se puede usar la comunicación entre el usuario y el administrador del sistema de impresión para identificar el trabajo que tiene problemas. Los subpasos son los siguientes.
1. Obtenga una lista de todos los servidores de impresión.
2. Recorra los servidores para consultar sus colas de impresión.
3. Dentro de cada iteración del bucle del servidor, recorra todas las colas del servidor para revisar sus tareas.
4. Dentro de cada paso del bucle de cola, recorra sus tareas y recopile información identificativa sobre aquellas que fueron enviadas por el usuario que se queja.
Cuando se haya identificado el trabajo de impresión problemático, examine las propiedades pertinentes para ver cuál podría ser el problema. Por ejemplo, ¿está el trabajo en un estado de error o se desconectó la impresora que atiende la cola antes de que el trabajo pudiera imprimirse?

El código siguiente es una serie de ejemplos de código. El primer ejemplo de código contiene el bucle a través de las colas de impresión. (Paso 1c anterior). La variable myPrintQueues es el PrintQueueCollection objeto del servidor de impresión actual.

El ejemplo de código comienza actualizando el objeto de cola de impresión actual con PrintQueue.Refresh. Esto garantiza que las propiedades del objeto representen con precisión el estado de la impresora física que representa. A continuación, la aplicación obtiene la colección de trabajos de impresión que se encuentran actualmente en la cola de impresión mediante GetPrintJobInfoCollection.

A continuación, la aplicación recorre la PrintSystemJobInfo colección y compara cada Submitter propiedad con el alias del usuario que se queja. Si coinciden, la aplicación agrega información identificativa sobre la tarea a la cadena que se presentará. (Las userName variables y jobList se inicializan anteriormente en la aplicación).

for each (PrintQueue^ pq in myPrintQueues)
{
   pq->Refresh();
   PrintJobInfoCollection^ jobs = pq->GetPrintJobInfoCollection();
   for each (PrintSystemJobInfo^ job in jobs)
   {
      // Since the user may not be able to articulate which job is problematic,
      // present information about each job the user has submitted.
      if (job->Submitter == userName)
      {
         atLeastOne = true;
         jobList = jobList + "\nServer:" + line;
         jobList = jobList + "\n\tQueue:" + pq->Name;
         jobList = jobList + "\n\tLocation:" + pq->Location;
         jobList = jobList + "\n\t\tJob: " + job->JobName + " ID: " + job->JobIdentifier;
      }
   }
}

foreach (PrintQueue pq in myPrintQueues)
{
    pq.Refresh();
    PrintJobInfoCollection jobs = pq.GetPrintJobInfoCollection();
    foreach (PrintSystemJobInfo job in jobs)
    {
        // Since the user may not be able to articulate which job is problematic,
        // present information about each job the user has submitted.
        if (job.Submitter == userName)
        {
            atLeastOne = true;
            jobList = jobList + "\nServer:" + line;
            jobList = jobList + "\n\tQueue:" + pq.Name;
            jobList = jobList + "\n\tLocation:" + pq.Location;
            jobList = jobList + "\n\t\tJob: " + job.JobName + " ID: " + job.JobIdentifier;
        }
    }// end for each print job
}// end for each print queue

For Each pq As PrintQueue In myPrintQueues
    pq.Refresh()
    Dim jobs As PrintJobInfoCollection = pq.GetPrintJobInfoCollection()
    For Each job As PrintSystemJobInfo In jobs
        ' Since the user may not be able to articulate which job is problematic,
        ' present information about each job the user has submitted.
        If job.Submitter = userName Then
            atLeastOne = True
            jobList = jobList & vbLf & "Server:" & line
            jobList = jobList & vbLf & vbTab & "Queue:" & pq.Name
            jobList = jobList & vbLf & vbTab & "Location:" & pq.Location
            jobList = jobList & vbLf & vbTab & vbTab & "Job: " & job.JobName & " ID: " & job.JobIdentifier
        End If
    Next job ' end for each print job

Next pq ' end for each print queue

En el siguiente ejemplo de código, se retoma la aplicación en el Paso 2. (Consulte lo anterior). El trabajo problemático se ha identificado y la aplicación solicita la información que lo identificará. A partir de esta información, crea los objetos PrintServer, PrintQueue y PrintSystemJobInfo.

En este momento, la aplicación contiene una estructura de bifurcación correspondiente a las dos formas de comprobar el estado de un trabajo de impresión:

Puede leer las marcas de la JobStatus propiedad que es de tipo PrintJobStatus.
Puede leer cada propiedad pertinente, como IsBlocked y IsInError.

En este ejemplo se muestran ambos métodos, por lo que el usuario se le ha indicado previamente qué método usar y respondió con "Y" si quería usar las marcas de la JobStatus propiedad . Consulte a continuación los detalles de los dos métodos. Por último, la aplicación usa un método denominado ReportQueueAndJobAvailability para informar sobre si el trabajo se puede imprimir en este momento del día. Este método se describe en Detectar si se puede imprimir un trabajo de impresión en este momento del día.

// When the problematic print job has been identified, enter information about it.
Console::Write("\nEnter the print server hosting the job (including leading slashes \\\\): " + "\n(press Return for the current computer \\\\{0}): ", Environment::MachineName);
String^ pServer = Console::ReadLine();
if (pServer == "")
{
   pServer = "\\\\" + Environment::MachineName;
}
Console::Write("\nEnter the print queue hosting the job: ");
String^ pQueue = Console::ReadLine();
Console::Write("\nEnter the job ID: ");
Int16 jobID = Convert::ToInt16(Console::ReadLine());

// Create objects to represent the server, queue, and print job.
PrintServer^ hostingServer = gcnew PrintServer(pServer, PrintSystemDesiredAccess::AdministrateServer);
PrintQueue^ hostingQueue = gcnew PrintQueue(hostingServer, pQueue, PrintSystemDesiredAccess::AdministratePrinter);
PrintSystemJobInfo^ theJob = hostingQueue->GetJob(jobID);

if (useAttributesResponse == "Y")
{

End If

Para comprobar el estado del trabajo de impresión mediante las marcas de la JobStatus propiedad, compruebe cada marca pertinente para ver si está establecida. La manera estándar de ver si un bit se establece en un conjunto de marcas de bits es realizar una operación AND lógica con el conjunto de marcas como un operando y la propia marca como la otra. Dado que el propio indicador tiene solo un bit activado, el resultado del AND lógico es que, como mucho, se activa ese mismo bit. Para averiguar si es o no, simplemente compare el resultado del AND lógico con la propia bandera. Para obtener más información, vea PrintJobStatus, el operador & (Referencia de C#) y FlagsAttribute.

Para cada atributo cuyo bit se establece, el código notifica esto a la pantalla de la consola y a veces sugiere una manera de responder. (El método HandlePausedJob al que se llama si el trabajo o la cola está en pausa se describe a continuación).

El método HandlePausedJob permite al usuario de la aplicación reanudar los trabajos en pausa de forma remota. Dado que puede haber una buena razón por la que se ha pausado la cola de impresión, el método comienza llamando a una decisión del usuario sobre si reanudarla. Si la respuesta es "Y", se llama al PrintQueue.Resume método .

A continuación, se le pedirá al usuario que decida si el trabajo en sí debe reanudarse, en caso de que esté pausado independientemente de la cola de impresión. (Comparar PrintQueue.IsPaused y PrintSystemJobInfo.IsPaused). Si la respuesta es "Y", se llama a PrintSystemJobInfo.Resume; de lo contrario, se llama a Cancel.
