Are PrintParams overriden by Windows Printer Preferences?

Question

Hi,
I want to create a form which prints silently, and bypasses all settings such as scaling and Duplex settings - I've created a sample form (attached) with the following script on a button click event
var myDoc = event.target;
        var pp = myDoc.getPrintParams();
        // Insert your Printer name here ....
        pp.printerName = "Brother MFC-7420 USB Printer";
        pp.DuplexType = 1;
        pp.nUpNumPagesH = 1;
        pp.nUpNumPagesV = 1;
        pp.tileScale = 1;
        pp.tileOverlap = 0;
        pp.nUpAutoRotate = false;
        pp.reversePages = false;
        pp.interactive = pp.constants.interactionLevel.silent;
        sfmTop.txtPrintOP.rawValue = pp.toSource();
        myDoc.print(0, "0", (xfa.host.numPages - 1).toString(), 0, 0, 0, 0, 0, pp);
Problem is that if the user in Windows has Printer Preferences set then it appears that these override the settings passed in th pp object.
My client needs to ensure that Duplex and reversing is turned off, but it doesn't happen if the printer preferences have these set!
Many Thanks,
Tim

Hi Tim,
Duplex can be specified in the Form Properties / Print Options tab:
I have tested it here and if the printer defaults is simplex and the form is set for duplex; then the form settings will override the printer defaults and print in duplex.
In your case you would need to set the form to print in simplex, as per the screen shot above. This should override the printer default of duplex printing.
This is a setting you make a design stage. I don't think you can change the duplex/simplex settings using script. At the end of the XML Source tab you will see the settings from the File / Form Properties tab:
<?PDFPrintOptions embedPrintOnFormOpen 0?>
<?PDFPrintOptions scalingPrefs 0?>
<?PDFPrintOptions enforceScalingPrefs 0?>
<?PDFPrintOptions paperSource 1?>
<?PDFPrintOptions duplexMode 1?>
But I don't think you can access these programmatically.
That said I think you can achieve what you want between the Form Properties and the xfa print parameters.
Good luck,
Niall.
