|
public abstract java.lang.String | getOutputFormat()Queries the factory for the document format that is emitted
by printers obtained from this factory.
|
public abstract javax.print.StreamPrintService | getPrintService(java.io.OutputStream out)Returns a 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 {@link StreamPrintService#dispose() dispose} method
before returning from the
{@link DocPrintJob#print(Doc, javax.print.attribute.PrintRequestAttributeSet) 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.

private static javax.print.StreamPrintServiceFactory$Services | getServices()
Services services =
(Services)AppContext.getAppContext().get(Services.class);
if (services == null) {
services = new Services();
AppContext.getAppContext().put(Services.class, services);
}
return services;
|
public abstract javax.print.DocFlavor[] | getSupportedDocFlavors()Queries the factory for the document flavors that can be accepted
by printers obtained from this factory.
|
private static java.util.ArrayList | initListOfFactories()
ArrayList listOfFactories = new ArrayList();
getServices().listOfFactories = listOfFactories;
return listOfFactories;
|
private static boolean | isMember(javax.print.DocFlavor flavor, javax.print.DocFlavor[] flavors)
for (int f=0; f<flavors.length; f++ ) {
if (flavor.equals(flavors[f])) {
return true;
}
}
return false;
|
public static javax.print.StreamPrintServiceFactory[] | lookupStreamPrintServiceFactories(javax.print.DocFlavor flavor, java.lang.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 flavor .
For example, the doc flavor is the document type that you want to
create, not the flavor of the
document before printing.
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).
ArrayList list = getFactories(flavor, outputMimeType);
return (StreamPrintServiceFactory[])
(list.toArray(new StreamPrintServiceFactory[list.size()]));
