[Scribus] Problem knowing how to print a 3 fold leaflet

[Emma Sunerton-Burl]

Hi
I am a newby here, loving Scribus so far. I have created a 3 fold 
leaflet - and it displays on the screen as I would expect with three 
columns on a landscape shaped paper the correct height and width. It has 
labelle dit as having 6 pages, displaying three next to each other to 
form the way a single sheet of paper would look if it was a three folded 
leaflet.

However when I go to print it out I can't get it to print all three 
pages on one A4 piece of paper, it comes out as 6 pages each on a 
separate piece of A4. What am I missing here? Sorry if it is a 
simplistic question, I have searched help files and looked at tutorials 
but can't seem to find the answer. Most examples talk about magazine 
type publications rather than threefold things.

Thank you for any help or pointers you can give me here.
Best regards
Emma
