这里面包含了一百多个JAVA源文件

// Look up all streaming factories
    StreamPrintServiceFactory[] factories
        = StreamPrintServiceFactory.lookupStreamPrintServiceFactories(null, null);
    
    // Find all streaming factories that support particular input formats;
    // in this case, GIF and postscript

        DocFlavor.INPUT_STREAM.GIF,
        DocFlavor.BYTE_ARRAY.POSTSCRIPT.getMimeType());
    
    // Use a factory to create a print service.
    // An output stream is required to create a print service.
    OutputStream fos = new BufferedOutputStream(
        new FileOutputStream("outfile.ps"));
    StreamPrintService service = factories[0].getPrintService(fos);
