My file has 3 pages,I need print 20 copies on paper both sides . The problem is that the second copy's first page is printed on the first copy's fourth page.Can u understand? The 2 copies can not be separated because some content is on the same paper.

Sorry, I do not understand.
Do you want to print
sheet1 side 1: document page 1
sheet 1 side 2: document page 2
sheet 2 side 1: document page 3
sheet 2 side 2: blank
?

Or do you want to print differently?

Exactly! I need separate the different copy for different people. So...

The new TRichView version supports printing in odd/even pages, and printing in reverse order.

For documents having even count of pages, it's simple. Print odd pages, flip paper stack, print even pages in reverse order.

However, for documents having odd count of pages, you need to remove last paper sheet from the stack before flipping.
I did not think about printing multiple copies...

In the next update, I'll add a new parameter allowing to print the last blank page, when printing only even pages for documents having odd count of pages.

For now, I can suggest:
1) add last blank page to the document
or
2) turn off "collate". In this case, it will be simpler to remove the last page, but you will need to separate copies yourself.

I got it,thank u!
