When I'm printing things onto an A4 sheet, I will do this:
(I use photoshop though!)
Create a new document - sized at 95mm x 171mm (personal sized filo paper)
Put the thing that i want printing on that, re-sized so it fits. Also leave a little gap to the left, for the holes.
Then I flatten all layers, and copy it all.
Create a new document - A4 sized.
Paste the 95mm x 171mm document onto the A4. Once it's on the A4, do not resize or anything.
Now you can add more pages to be printed - I think you can usually fit three on a page.
That works well for me. I last did it when making my dividers - though for this you've got to add the tabs afterwards (either on the A4 sheet in photoshop, or draw them when printed before cutting).
