PrintQueue::HasToner Property

Gets a value that indicates if the printer has toner.

Namespace:  System.Printing
Assembly:  System.Printing (in System.Printing.dll)

public:
property bool HasToner {
	bool get ();
}

Property Value

Type: System::Boolean
true if the current printer has toner; otherwise, false.

Some printer manufacturers may use this signal to indicate that toner is not low. Others may use it to indicate that the toner cartridge is present and properly inserted while using IsTonerLow to indicate that toner is low.

If the printer does not support a signal with this meaning, then the property is always false.

The following example shows how to use this property as part of a survey all printers for possible error status.

internal: 
   // Check for possible trouble states of a printer using its properties 
   static void SpotTroubleUsingProperties (System::String^% statusReport, System::Printing::PrintQueue^ pq) 
   {
      if (pq->HasPaperProblem)
      {
         statusReport = statusReport + "Has a paper problem. ";
      }
      if (!(pq->HasToner))
      {
         statusReport = statusReport + "Is out of toner. ";
      }
      if (pq->IsDoorOpened)
      {
         statusReport = statusReport + "Has an open door. ";
      }
      if (pq->IsInError)
      {
         statusReport = statusReport + "Is in an error state. ";
      }
      if (pq->IsNotAvailable)
      {
         statusReport = statusReport + "Is not available. ";
      }
      if (pq->IsOffline)
      {
         statusReport = statusReport + "Is off line. ";
      }
      if (pq->IsOutOfMemory)
      {
         statusReport = statusReport + "Is out of memory. ";
      }
      if (pq->IsOutOfPaper)
      {
         statusReport = statusReport + "Is out of paper. ";
      }
      if (pq->IsOutputBinFull)
      {
         statusReport = statusReport + "Has a full output bin. ";
      }
      if (pq->IsPaperJammed)
      {
         statusReport = statusReport + "Has a paper jam. ";
      }
      if (pq->IsPaused)
      {
         statusReport = statusReport + "Is paused. ";
      }
      if (pq->IsTonerLow)
      {
         statusReport = statusReport + "Is low on toner. ";
      }
      if (pq->NeedUserIntervention)
      {
         statusReport = statusReport + "Needs user intervention. ";
      }

      // Check if queue is even available at this time of day 
      // The following method is defined in the complete example.
      ReportAvailabilityAtThisTime(statusReport, pq);
   };
