[英]How to print report
我想打印一个JR报告。
我正在尝试此代码
JasperPrint jp = new JasperFillManager().fillReport("billReport", billId,
"jdbc:mysql://localhost/kpc_hospital");
JasperPrintManager.printReport(jp, true)
但是此代码不起作用。
您可以使用多种方法直接打印Jasper Report,而不显示“打印对话框”。
最简单的方法是:
Connection con;
String url="jdbc:mysql://localhost/mydb";
Class.forName("com.mysql.jdbc.Driver").newInstance();
con=(Connection) DriverManager.getConnection(url,"root","");
JasperReport jasperReport = JasperCompileManager.compileReport(fileName);
JasperPrint print = JasperFillManager.fillReport(jasperReport, parameter, con);
print.setPageHeight(100);
print.setPageWidth(80);
print.setOrientation(jasperReport.getOrientationValue().LANDSCAPE);
JasperPrintManager.printReport(print,false);
您还可以使用以下命令:
PrinterJob job = PrinterJob.getPrinterJob();
int selectedService = 0;
selectedService = 0;
PrintRequestAttributeSet printRequestAttributeSet = new HashPrintRequestAttributeSet();
printRequestAttributeSet.add(OrientationRequested.PORTRAIT);
printRequestAttributeSet.add(MediaSizeName.ISO_A0);
MediaSizeName mediaSizeName = MediaSize.findMedia(64,25,MediaPrintableArea.MM);
printRequestAttributeSet.add(mediaSizeName);
printRequestAttributeSet.add(new Copies(1));
JRPrintServiceExporter exporter;
exporter = new JRPrintServiceExporter();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasper_print);
exporter.setParameter(JRPrintServiceExporterParameter.PRINT_REQUEST_ATTRIBUTE_SET, printRequestAttributeSet);
exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PAGE_DIALOG, Boolean.FALSE);
exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PRINT_DIALOG, Boolean.TRUE);
exporter.exportReport();
job.print(printRequestAttributeSet);
