Duplexing Enumeration

Specifies whether a printer uses one-sided printing or some type of two-sided (duplex) printing.

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

public enum Duplexing
public enum Duplexing
public enum Duplexing
<object property="EnumerationValue" .../>

 Member nameDescription
OneSidedOutput prints on only one side of each sheet.  
TwoSidedLongEdgeOutput prints on both sides of each sheet, which flips along the edge parallel to the MediaSizeHeight
TwoSidedShortEdgeOutput prints on both sides of each sheet, which flips along the edge parallel to MediaSizeWidth
UnknownThe feature (whose options are represented by this enumeration) is set to an option not defined in the Print Schema

Use the values of this type primarily for these purposes:

  • As members of the DuplexingCapability collection, which is a property of PrintCapabilities, these values indicate the kinds of one-sided and two-sided printing that the printer supports.

  • As the value of the Duplexing property of a PrintTicket, they direct the printer to use one-sided printing or some kind of two-sided printing.

The Unknown value is never used in properties of PrintCapabilities objects.

You should never set a PrintTicket property to Unknown. If some other PrintTicket producing application has created a PrintTicket document that sets the duplexing feature to an unrecognized duplexing option (that is, an option that is not defined in the Print Schema), then a PrintTicket object in your application that is constructed with that document will have Unknown as the value of the Duplexing property.

Although the PrintTicket and PrintCapabilities classes cannot be inherited, you can extend the Print Schema to recognize print device features that are not accounted for in the PrintTicket or PrintCapabilities classes. For more information see How to: Extend the Print Schema and Create New Print System Classes.

The following example shows how to test a printer's capabilities and configure the print job to take advantage of them. For the complete example, see Creating an XPS Document Sample.
