I'm using the following inorder to print a report using an xml file that was build using iReport.
It prints the report but I have 2 questions if I may:
1. How can I show field name in the grey area of the report beneath the title, so one would know what is the name of the column? now its a blank grey row.
2. If I have namy fields to print Can I set the report to be devided to 2 or 3 so all the fields will be shown? Now it shows all fields in the same A4 page so it go's one on top of each other.
public static void PrintReport(int reportID,String printerDescription){
Report currReport = ReportsManager.instance().getReport(reportID);
String xmlFileName = Configuration.instance().getReportTemplateFilesFolder() + File.separator + currReport.getFilename();
PrintService selectedPrintService = ReportsManager.instance().getPrintService(printerDescription);

if (selectedPrintService != null) {
PrintServiceAttributeSet printAttributeSet = selectedPrintService.getAttributes();
ByteArrayOutputStream compiledOutput = new ByteArrayOutputStream();
JasperCompileManager.compileReportToStream(new FileInputStream(xmlFileName), compiledOutput);
Map parameters = new HashMap();

ByteArrayInputStream in = new ByteArrayInputStream(compiledOutput.toByteArray());

JasperPrint jasperPrint = JasperFillManager.fillReport(in, parameters, Database.instance().getConnection());

JRAbstractExporter printExporter = new JRPrintServiceExporter();
printExporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PAGE_DIALOG, new Boolean(false));
printExporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PRINT_DIALOG, new Boolean(false));
printExporter.setParameter(JRPrintServiceExporterParameter.PRINT_SERVICE_ATTRIBUTE_SET, printAttributeSet);
catch (JRException e)
catch (ModelException me) {
logger.error("", me);
catch (Exception e)
When I'm displaying the report as PDF It shows the field names and also prints it if I print it from the PDF itself But by printing directly it doesn't.
Please advise
