Like the PrintQueue class, this enumeration handles the print queue and the physical printer (or device) as one unit. Some values represent the status of the physical device and others represent the status of the print queue program that is running on the print server.
Use this enumeration to provide values for the QueueStatus property of the PrintQueue class.
The following example shows how to use this enumeration as part of a survey all printers for possible error status.
internal: // Check for possible trouble states of a printer using the flags of the QueueStatus property static void SpotTroubleUsingQueueAttributes (System::String^% statusReport, System::Printing::PrintQueue^ pq) { if ((pq->QueueStatus & PrintQueueStatus::PaperProblem) == PrintQueueStatus::PaperProblem) { statusReport = statusReport + "Has a paper problem. "; } if ((pq->QueueStatus & PrintQueueStatus::NoToner) == PrintQueueStatus::NoToner) { statusReport = statusReport + "Is out of toner. "; } if ((pq->QueueStatus & PrintQueueStatus::DoorOpen) == PrintQueueStatus::DoorOpen) { statusReport = statusReport + "Has an open door. "; } if ((pq->QueueStatus & PrintQueueStatus::Error) == PrintQueueStatus::Error) { statusReport = statusReport + "Is in an error state. "; } if ((pq->QueueStatus & PrintQueueStatus::NotAvailable) == PrintQueueStatus::NotAvailable) { statusReport = statusReport + "Is not available. "; } if ((pq->QueueStatus & PrintQueueStatus::Offline) == PrintQueueStatus::Offline) { statusReport = statusReport + "Is off line. "; } if ((pq->QueueStatus & PrintQueueStatus::OutOfMemory) == PrintQueueStatus::OutOfMemory) { statusReport = statusReport + "Is out of memory. "; } if ((pq->QueueStatus & PrintQueueStatus::PaperOut) == PrintQueueStatus::PaperOut) { statusReport = statusReport + "Is out of paper. "; } if ((pq->QueueStatus & PrintQueueStatus::OutputBinFull) == PrintQueueStatus::OutputBinFull) { statusReport = statusReport + "Has a full output bin. "; } if ((pq->QueueStatus & PrintQueueStatus::PaperJam) == PrintQueueStatus::PaperJam) { statusReport = statusReport + "Has a paper jam. "; } if ((pq->QueueStatus & PrintQueueStatus::Paused) == PrintQueueStatus::Paused) { statusReport = statusReport + "Is paused. "; } if ((pq->QueueStatus & PrintQueueStatus::TonerLow) == PrintQueueStatus::TonerLow) { statusReport = statusReport + "Is low on toner. "; } if ((pq->QueueStatus & PrintQueueStatus::UserIntervention) == PrintQueueStatus::UserIntervention) { statusReport = statusReport + "Needs user intervention. "; } // Check if queue is even available at this time of day // The method below is defined in the complete example. ReportAvailabilityAtThisTime(statusReport, pq); };
