Duplex Printing whilst using mulitple printer Trays

Curtis_James

Hi,

Am using WP Version 4 and I am having problems duplex printing from multiple printer trays.

Basically, I want the first page to print out on Headed Paper, the second page to print on the back of the headed paper and all subsequent pages to print from another tray front and back on blank paper.

I have attempted a number of ways but I am having no luck.
I have the printer set to duplex by default.

Here is some code that was one of my attempts:

Code

vPrintTrays := TStringList.Create;
  wprtLetter.PrintParameter.GetPaperBins(vPrintTrays);
  wprtLetter.PrintParameter.FirstPagePaperSource := Word(vPrintTrays.Objects[vPrintTrays.IndexOf('Cassette 2')]); //Headed Paper
  wprtLetter.PrintParameter.AllPagePaperSource:= Word(vPrintTrays.Objects[vPrintTrays.IndexOf('Cassette 2')]);  //Headed Paper
  wprtLetter.PrintParameter.PageRange := wprPageList;
  if (wprtLetter.CountPages > 1) then
	wprtLetter.PrintParameter.PageList := '1,2'
  else
	wprtLetter.PrintParameter.PageList := '1';
  wprtLetter.Print;
  if (wprtLetter.CountPages > 2) then
  begin
	wprtLetter.PrintParameter.PrintOptions := [];
	wprtLetter.PrintParameter.FirstPagePaperSource := Word(vPrintTrays.Objects[vPrintTrays.IndexOf('Cassette 1')]); //Blank Paper
	wprtLetter.PrintParameter.AllPagePaperSource:= Word(vPrintTrays.Objects[vPrintTrays.IndexOf('Cassette 1')]);  //Blank Paper
	wprtLetter.PrintParameter.PageRange := wprPageList;
	wprtLetter.PrintParameter.PageList := '3-'+ IntToStr(wprtLetter.CountPages);
	wprtLetter.Print;
  end;

(wprtLetter is a TWPRichText Object)

In this situation printing a three page document ends up on 3 seperate pages, the first two headed and the last blank.
Any help would be much appreciated.
