Ejemplos

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 PageOrderCapability colección, una propiedad de PrintCapabilities, estos valores indican el tipo de orden de las páginas que admite una impresora.As members of the PageOrderCapability collection, a property of PrintCapabilities, these values indicate the type of page order that a printer supports. (Muchas impresoras admiten ambos tipos).(Many printers support both types.)

  • Como el valor de la PageOrder propiedad de un PrintTicket, el valor indica a la impresora para imprimir el resultado en un orden especificado.As the value of the PageOrder property of a PrintTicket, the value directs a printer to print output in a specified order.

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 orden de página en una opción no reconocida (es decir, una opción que no está definida en el Print Schema), un PrintTicket objeto en la aplicación que se construye con ese documento tendrá desconocido como el valor de la PageOrder propiedad.If some other PrintTicket producing application has created a PrintTicket document that sets the page order feature to an unrecognized 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 PageOrder 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.
