Jak wydrukować raporty Jaspera na określonej drukarce?

Question

Wszystko czego chcę, to wydrukować JasperReport bez wyboru drukarki. Szukałem go, ale nie ma dobrego rozwiązania, które działa. To jest część zapasowa mojego kodu:

//compile to .jasper 
String report = JasperCompileManager.compileReportToFile(sourceFileName); 

//fill the report 
JasperPrint jasperPrint = JasperFillManager.fillReport(report, parameter, dataSource); 

//print the report  
JasperPrintManager.printReport(jasperPrint, true); 

Zamiast prostego printReport chcę wybrać drukarkę. czy jest jakikolwiek sposób to zrobić?

Answer 1

Jak to ma być:

try { 

    String report = JasperCompileManager.compileReportToFile(sourceFileName); 

    JasperPrint jasperPrint = JasperFillManager.fillReport(report, para, ds); 

    PrinterJob printerJob = PrinterJob.getPrinterJob(); 

    PageFormat pageFormat = PrinterJob.getPrinterJob().defaultPage(); 
    printerJob.defaultPage(pageFormat); 

    int selectedService = 0; 

    AttributeSet attributeSet = new HashPrintServiceAttributeSet(new PrinterName(printerNameShort, null)); 

    PrintService[] printService = PrintServiceLookup.lookupPrintServices(null, attributeSet); 

    try { 
     printerJob.setPrintService(printService[selectedService]); 

    } catch (Exception e) { 

     System.out.println(e); 
    } 
    JRPrintServiceExporter exporter; 
    PrintRequestAttributeSet printRequestAttributeSet = new HashPrintRequestAttributeSet(); 
    printRequestAttributeSet.add(MediaSizeName.NA_LETTER); 
    printRequestAttributeSet.add(new Copies(1)); 

    // these are deprecated 
    exporter = new JRPrintServiceExporter(); 
    exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint); 
    exporter.setParameter(JRPrintServiceExporterParameter.PRINT_SERVICE, printService[selectedService]); 
    exporter.setParameter(JRPrintServiceExporterParameter.PRINT_SERVICE_ATTRIBUTE_SET, printService[selectedService].getAttributes()); 
    exporter.setParameter(JRPrintServiceExporterParameter.PRINT_REQUEST_ATTRIBUTE_SET, printRequestAttributeSet); 
    exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PAGE_DIALOG, Boolean.FALSE); 
    exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PRINT_DIALOG, Boolean.FALSE); 
    exporter.exportReport(); 

} catch (JRException e) { 
    e.printStackTrace(); 
}

Oto proste rozwiązanie do drukowania raportu jaspis na konkretnej drukarki Tworzenie Jedna metoda Wybierz drukarki raportu & druku

private void PrintReportToPrinter(JasperPrint jp) throws JRException { 
    // TODO Auto-generated method stub 
    PrintRequestAttributeSet printRequestAttributeSet = new HashPrintRequestAttributeSet(); 
    // printRequestAttributeSet.add(MediaSizeName.ISO_A4); //setting page size 
    printRequestAttributeSet.add(new Copies(1)); 

    PrinterName printerName = new PrinterName("Microsoft XPS Document Writer", null); //gets printer 

    PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet(); 
    printServiceAttributeSet.add(printerName); 

    JRPrintServiceExporter exporter = new JRPrintServiceExporter(); 

    exporter.setParameter(JRExporterParameter.JASPER_PRINT, jp); 
    exporter.setParameter(JRPrintServiceExporterParameter.PRINT_REQUEST_ATTRIBUTE_SET, printRequestAttributeSet); 
    exporter.setParameter(JRPrintServiceExporterParameter.PRINT_SERVICE_ATTRIBUTE_SET, printServiceAttributeSet); 
    exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PAGE_DIALOG, Boolean.FALSE); 
    exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PRINT_DIALOG, Boolean.FALSE); 
    exporter.exportReport(); 
} 

następnie wywołaj tę metodę, np.

/* your code*/ 
Map parameters = new HashMap(); 
parameters.put("ckotid", kid); 

try { 
    JasperDesign jsd = JRXmlLoader.load("report\\bill\\check_kot.jrxml"); 
    JasperReport jr = JasperCompileManager.compileReport(jsd); 
    JasperPrint jp = JasperFillManager.fillReport(jr, parameters, con); 
    //JasperPrintManager.printPage(jp, 0, false); 
    //JasperPrint jp =reportEngine.fillReport() ;//it returns stream 
    PrintReportToPrinter(jp);//call method 

Answer 3

prostu użyć tego .Nie trzeba więcej kodu obsłużyć Jasper

JasperPrintManager.printReport(jasperPrint, false); 

u używać prawda pokaże okno

Testowałem go Epson TM T82 to działało.

Answer 4

Te kody są przestarzałe. JRPrintServiceExporter.setParameter został przestarzały w JasperReports 5.6. Wprowadzili nowy interfejs eksportera i zmodernizowali wszystkich eksporterów, aby mieć ExporterInput, ReportExportConfiguration, ExporterConfiguration, ExporterOutput. Patrz niżej linkiem

http://jasperreports.sourceforge.net/api/net/sf/jasperreports/export/Exporter.html

Oznacza to, że zamiast setParameter, trzeba stworzyć konfigurację:

private void PrintReportToPrinter(JasperPrint jasperPrint) throws JRException { 

//Get the printers names 
PrintService[] services = PrintServiceLookup.lookupPrintServices(null, null); 

//Lets set the printer name based on the registered printers driver name (you can see the printer names in the services variable at debugging) 
String selectedPrinter = "Microsoft XPS Document Writer"; 
// String selectedPrinter = "\\\\S-BPPRINT\\HP Color LaserJet 4700"; // examlpe to network shared printer 

System.out.println("Number of print services: " + services.length); 
PrintService selectedService = null; 

//Set the printing settings 
PrintRequestAttributeSet printRequestAttributeSet = new HashPrintRequestAttributeSet(); 
printRequestAttributeSet.add(MediaSizeName.ISO_A4); 
printRequestAttributeSet.add(new Copies(1)); 
if (jasperPrint.getOrientationValue() == net.sf.jasperreports.engine.type.OrientationEnum.LANDSCAPE) { 
    printRequestAttributeSet.add(OrientationRequested.LANDSCAPE); 
} else { 
    printRequestAttributeSet.add(OrientationRequested.PORTRAIT); 
} 
PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet(); 
printServiceAttributeSet.add(new PrinterName(selectedPrinter, null)); 

JRPrintServiceExporter exporter = new JRPrintServiceExporter(); 
SimplePrintServiceExporterConfiguration configuration = new SimplePrintServiceExporterConfiguration(); 
configuration.setPrintRequestAttributeSet(printRequestAttributeSet); 
configuration.setPrintServiceAttributeSet(printServiceAttributeSet); 
configuration.setDisplayPageDialog(false); 
configuration.setDisplayPrintDialog(false); 

exporter.setExporterInput(new SimpleExporterInput(jasperPrint)); 
exporter.setConfiguration(configuration); 

//Iterate through available printer, and once matched with our <selectedPrinter>, go ahead and print! 
if(services != null && services.length != 0){ 
    for(PrintService service : services){ 
     String existingPrinter = service.getName(); 
     if(existingPrinter.equals(selectedPrinter)) 
     { 
      selectedService = service; 
      break; 
     } 
    } 
} 
if(selectedService != null) 
{ 
    try{ 
     //Lets the printer do its magic! 
     exporter.exportReport(); 
    }catch(Exception e){ 
System.out.println("JasperReport Error: "+e.getMessage()); 
    } 
}else{ 
    System.out.println("JasperReport Error: Printer not found!"); 
}} 

Można drukować przez ten kod na drukarce sieciowej podzielił też.
