Empty pages: beginning / end on Printout

Hello!

I have got 2 Masterpages and several pages, all their presence is set to visible.

• Master_1:
  Master_2
• Page_1: Associated to Master_1
  Page_2: Associated to Master_2
  Page_3: Assiciated to Master_2

Sometimes I have to print all pages (Page_1 to Page_3), sometimes Page_3 only.

What happens:

• On Printout of all pages: I do not get any additional extra pages. OK!
• On Printout of Page 3:
  • on the event: prePrint for Page_1 and Page_2: this.presence="hidden";
  • I get 2 empty pages: one on the beginning of the printOut and one at the end of the Printout

Question:

• Which settings for all the MasterPages and all other Pages are needed to prevent the empty pages during printout?

Thanks for any answer!
