ListView - when print items from ListView only visible items are printed? why?

Hello!

I have one ListView on my Activity with 50 items.
Because of size of ListView, only 5 items are visible in this ListView,but when I'm scrolling this ListView I see normally all 50 items.
This is OK, but the problem is, that I want to print this ListView and on print there are only 5 items printed, only the visible ones.
Where is the problem? Please for the help and quick answer......

Best regards
