e701. The Quintessential Printing Program Using a Streaming Printing ServiceA streaming print service is used to convert print data from one format to another. Unlike a print service that prints to a printer, a streaming print service writes to an output stream. This example demonstrates a program that prints an image to a postscript-generating streaming print service.import java.io.*; import javax.print.*; public class BasicStream { public static void main(String[] args) { try { // Open the image file InputStream is = new BufferedInputStream( new FileInputStream("filename.gif")); // Prepare the output file to receive the postscript OutputStream fos = new BufferedOutputStream( new FileOutputStream("filename.ps")); // Find a factory that can do the conversion DocFlavor flavor = DocFlavor.INPUT_STREAM.GIF; StreamPrintServiceFactory[] factories = StreamPrintServiceFactory.lookupStreamPrintServiceFactories( flavor, DocFlavor.BYTE_ARRAY.POSTSCRIPT.getMimeType()); if (factories.length > 0) { StreamPrintService service = factories[0].getPrintService(fos); // Create the print job DocPrintJob job = service.createPrintJob(); Doc doc = new SimpleDoc(is, flavor, null); // Monitor print job events; for the implementation of PrintJobWatcher, // see e702 Determining When a Print Job Has Finished PrintJobWatcher pjDone = new PrintJobWatcher(job); // Print it job.print(doc, null); // Wait for the print job to be done pjDone.waitForDone(); // It is now safe to close the streams } is.close(); fos.close(); } catch (PrintException e) { } catch (IOException e) { } } }
