[JAVA2D] problems when printing with the duplex option

[David Ortega del Campo]

Hi Currently we are printing documents from Java, but we have problems when printing images with the duplex option. We set DUPLEX option when printing, but the printer don't print boths sides of the pages (Our printer suports boths sides mode). Our code is similar to:     PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();     aset.add(Sides.DUPLEX);     DocFlavor psInFormat = DocFlavor.SERVICE_FORMATTED.PRINTABLE;     PrintService[] services = PrintServiceLookup.lookupPrintServices(psInFormat, aset);     if (services.length > 0)     {       try{         PrinterJob printerjob = PrinterJob.getPrinterJob();         ... Thanks for any insights.
