PrintQueue.HasToner Property

Gets a value that indicates if the printer has toner.

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

public bool HasToner { get; }
/** @property */
public boolean get_HasToner ()

public function get HasToner () : boolean

Not applicable.

Property Value

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. For the complete sample, see Survey Status of Printers Sample.

// Check for possible trouble states of a printer using its properties
internal static void SpotTroubleUsingProperties(ref String statusReport, 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. ";
