public abstract class StreamPrintServiceFactory extends Object
StreamPrintServiceFactoryis the factory for
StreamPrintServiceinstances, which can print to an output stream in a particular document format described as a mime type. A typical output document format may be Postscript(TM).
This class is implemented by a service and located by the implementation using the SPI JAR File specification.
Applications locate instances of this class by calling the
lookupStreamPrintServiceFactories(DocFlavor, String) method.
Applications can use a
StreamPrintService obtained from a
factory in place of a
PrintService which represents a
physical printer device.
|Constructor and Description|
|Modifier and Type||Method and Description|
Queries the factory for the document format that is emitted by printers obtained from this factory.
Queries the factory for the document flavors that can be accepted by printers obtained from this factory.
Locates factories for print services that can be used with a print job to output a stream of data in the format specified by
public static StreamPrintServiceFactory lookupStreamPrintServiceFactories(DocFlavor flavor, String outputMimeType)
outputMimeType parameter describes the document type that
you want to create, whereas the
flavor parameter describes the
format in which the input data will be provided by the application
Although null is an acceptable value to use in the lookup of stream printing services, it's typical to search for a particular desired format, such as Postscript(TM).
flavor- of the input document type - null means match all types.
outputMimeType- representing the required output format, used to identify suitable stream printer factories. A value of null means match all formats.

public abstract StreamPrintService getPrintService(OutputStream out)
StreamPrintServicethat can print to the specified output stream. The output stream is created and managed by the application. It is the application's responsibility to close the stream and to ensure that this Printer is not reused. The application should not close this stream until any print job created from the printer is complete. Doing so earlier may generate a
PrinterExceptionand an event indicating that the job failed.
PrintService connected to a physical printer
can be reused,
StreamPrintService connected to a stream cannot.
StreamPrintService may be disposed by
the print system with
before returning from the
DocPrintJob so that the print system knows
this printer is no longer usable.
This is equivalent to a physical printer going offline - permanently.
Applications may supply a null print stream to create a queryable
service. It is not valid to create a PrintJob for such a stream.
Implementations which allocate resources on construction should examine
the stream and may wish to only allocate resources if the stream is
out- destination stream for generated output.
