public abstract class StreamPrintServiceFactory extends Object
StreamPrintServiceFactory is the factory for
StreamPrintService instances,
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.

| Modifier and Type | Method and Description |
|---|---|
abstract String |
getOutputFormat()
Queries the factory for the document format that is emitted
by printers obtained from this factory.
|
abstract StreamPrintService |
getPrintService(OutputStream out)
Returns a
StreamPrintService that can print to
the specified output stream. |
abstract DocFlavor[] |
getSupportedDocFlavors()
Queries the factory for the document flavors that can be accepted
by printers obtained from this factory.

lookupStreamPrintServiceFactories(DocFlavor flavor,
String outputMimeType)
Locates factories for print services that can be used with
a print job to output a stream of data in the
format specified by
outputMimeType. |
public static StreamPrintServiceFactory[] lookupStreamPrintServiceFactories(DocFlavor flavor, String outputMimeType)
outputMimeType.
The 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
to the StreamPrintService.
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).

identify suitable stream printer factories. A value of null means

public abstract DocFlavor[] getSupportedDocFlavors()
public abstract StreamPrintService getPrintService(OutputStream out)
StreamPrintService that 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 PrinterException and an event indicating that the
job failed.
Whereas a PrintService connected to a physical printer
can be reused,
a StreamPrintService connected to a stream cannot.
The underlying StreamPrintService may be disposed by
the print system with
the dispose method
before returning from the
print
method of 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
non-null.
