Hello

I can not seem to get duplex working.

I have tried setting duplex on the printer, I get only single pages.

I tried creating a custom printer and changing the settings using the following code

procedure TPDFViewerMainForm.PrintWithDialog(asPrintJobTitle: string = 'ExitCare Print Job');
var
iPrintOptions: integer;
iPrintFrom: integer;
iPrintTo: integer;
SPrinterName:String;
begin
PrintDialog.MaxPage := iTotalPages;
PrintDialog.MinPage := 1;
printDialog.FromPage := 1;
printDialog.ToPage := iTotalPages;

if PrintDialog.Execute then
    begin
      iPrintOptions := PDFFile.PrintOptions(0, 0, 'ExitCare Print Job');
      if PrintDialog.PrintRange = prAllpages then
        begin
          iPrintFrom := 1;
          iPrintTo := iTotalPages;
        end
      else
        begin
          iPrintFrom := printDialog.FromPage;
          iPrintTo := printDialog.ToPage;
        end;
        SPrinterName:=PDFFIle.NewCustomPrinter(Printer.Printers[Printer.PrinterIndex]);
       PDFFIle.SetupCustomPrinter(SPrinterName,7,3);

PDFFile.PrintDocument(SPrinterName, iPrintFrom, iPrintTo, iPrintOptions);
end;
end;

Still only get single pages. Nothing I have tried seems to print in duplex mode. I have tested the same PDF in both Adobe Reader and Gnostice and they print in duplex fine.

I am testing using the 7.16 beta, but this also happend in 7.15.

Thanks

Bern

After some more testing, the only way I can get QuickPDF to print duplex is if I use the PrintDocumentToPrinterObject function.

PrintDocument with duplex works fine for me in 7.14 (and older) version. I'll get & try 7.15 later, but I'll be very surprised if it worked in 7.14 and not 7.15.

What version of Delphi are you using?

Just tried it in 7.15 and it works fine for me.

Not sure if this may be what is confusing or not but with the code above it does not matter what you select in the printer dialog.

Duplexing is set by SetupCustomPrinter(SPrinterName,7,3);

If you leave off or comment out SetupCustomPrinter(SPrinterName,7,3); it prints simplex regardless of selecting duplex in the printer dialog.

With the code the way you have above it will duplex every time.

Well all I know is it does not work for me, and i have tried on multiple printers.
Doesn't really matter at this point, due to a lack of response on both here and from their support, management here as decided to go with a different PDF solution.

Hi Bern,
