PrintCapabilities.DuplexingCapability Property

Gets a collection of values that identify whether and how a printer can perform two-sided printing.

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

public ReadOnlyCollection<Duplexing> DuplexingCapability { get; }
/** @property */
public ReadOnlyCollection<Duplexing> get_DuplexingCapability ()

public function get DuplexingCapability () : ReadOnlyCollection<Duplexing>

You cannot use this property in XAML.

Property Value

A ReadOnlyCollection of Duplexing values.

If the printer does not support duplexing, the collection is empty.

This property corresponds to the Print Schema's JobDuplexAllDocumentsContiguously keyword, not the DocumentDuplex keyword.

The following example shows how to use this property to determine the capabilities of a specific printer and how to configure a print job to take advantage of them. For the complete example, see Creating an XPS Document Sample.
