can't print datawindow in Not Collated (PB9)

Hi all,

I used PB9. I need to print a datawindow with several copies with not collat
ed. That means, if the datawindow retrieved 3 pages, I want to print it in 2
 copies. I can't print it this sequence: page 1, page 1, and then page 2 and
 page 2.

It always print in page 1 then page 2, and again.

No matter I've tried it in design time and run time.

I've tried to set the lstr_printdlg.s_printer.b_collate to False
before it run dw.print(). However, it still failed.

Then, I tried to print the datawindow in design time. The check box, collate
 copies, in 'print specification' was set to false.
And also uncheck the 'collate' in printer setup dialogue.
It also failed.

Does any successfull case to print a DW in not collated in PB9?

Please advise me. Thank you very much.
