/**
* This class extends {@link PrintService} and represents a
* print service that prints data in different formats to a
* client-provided output stream.
* This is principally intended for services where
* the output format is a document type suitable for viewing
* or archiving.
* The output format must be declared as a mime type.
* This is equivalent to an output document flavor where the
* representation class is always "java.io.OutputStream"
* An instance of the <code>StreamPrintService</code> class is
* obtained from a {@link StreamPrintServiceFactory} instance.
* <p>
* Note that a <code>StreamPrintService</code> is different from a
* <code>PrintService</code>, which supports a
* {@link javax.print.attribute.standard.Destination Destination}
* attribute. A <code>StreamPrintService</code> always requires an output
* stream, whereas a <code>PrintService</code> optionally accepts a
* <code>Destination</code>. A <code>StreamPrintService</code>
* has no default destination for its formatted output.
* Additionally a <code>StreamPrintService</code> is expected to generate
output in
* a format useful in other contexts.
* StreamPrintService's are not expected to support the Destination attribute.
