如何在指定的打印机上打印 Jasper Reports？

Question

我想要的只是打印 JasperReport 而无需用户选择打印机。我搜索了它，但没有很好的解决方案。这是我的代码的相关部分：

//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);

我想选择一台打印机，而不是简单的 printReport。有没有办法做到这一点？

Answer 1

应该是这样的：

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();
}

这是在特定打印机上打印碧玉报告的简单解决方案 为选择打印机和打印报告创建一种方法

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();
}

然后像这样调用这个方法

/* 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

这些代码已过时。 JRPrintServiceExporter.setParameter 在 JasperReports 5.6 中被弃用。他们引入了新的接口 Exporter，并对所有导出器进行了改造，使其具有 ExporterInput、ReportExportConfiguration、ExporterConfiguration、ExporterOutput。见以下链接

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

这意味着你需要创建配置而不是setParameter：

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!");
}}

您也可以通过此代码打印到网络共享打印机。

只需使用这个。不需要更多的代码来处理 jasper

JasperPrintManager.printReport(jasperPrint, false);

你使用true它会显示窗口

我测试过 epson TM T82 它奏效了。
