Reflections & Reference Objects – PrinterJob can’t detect the new default printer in JSP/Servlet

Hi,

I solved my problem but I’m not sure it applies to your problems too.

I was using JRPrintServiceExporter and it does not use the default print service, but the first print service returned by PrintServiceLookup.lookupPrintServices(DocFlavor, AttributeSet).

Simply adding this line:

PrintService defaultPrintService = PrintServiceLookup.lookupDefaultPrintService();

And adding that as an export parameter:

exporter.setParameter(JRPrintServiceExporterParameter.PRINT_SERVICE, defaultPrintService);

Solves the problem.

example code is below:

JasperPrint print = JasperFillManager.fillReport(fileName, null, con);
                //JasperPrintManager.printReport(print, false);
                PrintRequestAttributeSet printRequestAttributeSet = new HashPrintRequestAttributeSet();
                PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet();

                //printServiceAttributeSet.add(MediaSizeName.ISO_A4);
                //print to your printer by printer name
                // printServiceAttributeSet.add(new PrinterName(“Microsoft Office Document Image Writer", null));
                printRequestAttributeSet.add(new Copies(iCopies[i]));

                // print to default printer
                JRPrintServiceExporter exporter = new JRPrintServiceExporter();
                PrintService defaultPrintService = PrintServiceLookup.lookupDefaultPrintService();
                exporter.setParameter(JRPrintServiceExporterParameter.PRINT_SERVICE, defaultPrintService);

                exporter.setParameter(JRExporterParameter.JASPER_PRINT, print);
                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);

                //System.out.println(“export to printer");

                exporter.exportReport();
