Ah, I think I see the issue now. Maybe 😉

You're shoving the raw PDF file into an outq entry and letting it stream directly to a PDF capable printer correct ?

If so, I believe you have absolutely no control over duplexing because the PDF streams directly to the printer and the printer does its magic. Might need to check with printer vendor to see if the PDF content itself or a printer config setting can somehow affect duplexing.

In our case with iForms we actually re-render the PDF to a print stream so that gives us control over the printer settings and duplexing settings when printing the PDF so each individual document can have separate settings if needed.

I would check with the printer provider on config settings first.

subject: Re: Print PDF in duplex mode

Hm ... where would I see if the print driver controls it or not? The outqueue description says:

Manufacturer type and model? . . . . . :? ?*HP520

Below my code to read the PDF and send it over to the printer:

AS400 as400;
as400 = db_connect.as400;

SpooledFile spooledFile = null;

PrintParameterList parms = new PrintParameterList();

parms.setParameter(PrintObject.ATTR_COPIES, documentRequest.numberOfCopies);

String outqueueName = "/QSYS.LIB/QUSRSYS.LIB/" + outqueue + ".OUTQ"; OutputQueue outputQueue = new OutputQueue(as400, outqueueName); parms.setParameter(PrintObject.ATTR_OUTPUT_QUEUE, outputQueue.getPath()); parms.setParameter(PrintObject.ATTR_HOLD, hold ? "*YES" : "*NO"); parms.setParameter(PrintObject.ATTR_SAVE, save ? "*YES" : "*NO"); parms.setParameter(PrintObject.ATTR_SPOOLFILE, ""); parms.setParameter(PrintObject.ATTR_DUPLEX, "*YES"); parms.setParameter(PrintObject.ATTR_USERDATA, documentRequest.depot + documentRequest.movementOrder);

SpooledFileOutputStream outputStream = new SpooledFileOutputStream(as400, parms, null, null);

InputStream fisPDF = null;
InputStream finalIS = null;

switch (inputMode) {
case "zpl":
System.out.println("Input mode is zpl"); finalIS = new ByteArrayInputStream(data.getBytes());
break;
case "pdf":
System.out.println("Input mode is pdf"); System.out.println("Source data: " + data); fisPDF = new FileInputStream(data); finalIS = fisPDF; break;
default:
}

Integer bytesRead;
byte[] buf = new byte[2048];


do {
bytesRead = finalIS.read(buf);
if (bytesRead != -1) {
outputStream.write(buf, 0, bytesRead);
}
} while (bytesRead != -1);

outputStream.flush();
outputStream.close();
