Comentarios

Los valores de este tipo se utilizan principalmente para estos fines:Use the values of this type primarily for these purposes:

  • Como los miembros de la DuplexingCapability colección, que es una propiedad de PrintCapabilities, estos valores indican los tipos de impresión de un lado y a dos caras que admite la impresora.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.

  • Como el valor de la Duplexing propiedad de un PrintTicket, indican a la impresora para usar la impresión en una cara o algún tipo de dos caras.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.

El desconocido valor nunca se utiliza en las propiedades de PrintCapabilities objetos.The Unknown value is never used in properties of PrintCapabilities objects.

Nunca debe establecer un PrintTicket propiedad desconocido.You should never set a PrintTicket property to Unknown. Si algún otro PrintTicket generar la aplicación ha creado un documento PrintTicket que establece la característica de impresión a doble cara en una opción no reconocida de duplicación (es decir, una opción que no está definida en el esquema de impresión ), un PrintTicket objeto en la aplicación que se construye con ese documento tendrá desconocido como el valor de la Duplexing propiedad.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.

Aunque el PrintTicket y PrintCapabilities no se puede heredar las clases, puede ampliar el Print Schema para reconocer las características del dispositivo de impresión que no se recogen en el PrintTicket o PrintCapabilities clases.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. Para obtener más información, vea Cómo: Extender el esquema de impresión y crear nuevas clases de sistema de impresión.For more information see How to: Extend the Print Schema and Create New Print System Classes.
