如何在指定的打印机中打印Jasper Reports？

Question

我想要的只是在没有用户选择打印机的情况下打印JasperReport.我搜索了它,但没有好的解决方案可行.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);

我想要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

这是它应该是这样的:

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 jasper 报告的简单解决方案 创建选择打印机和打印报告的一种方法

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
