I assume you are using CUPS as the print spooler.
printing with the number-up option is implemented by scaling down the pages 
to be printed, i.e. with number-up=2, the pages are scaled down by sqrt(2).

To get your problem solved, you have two choices:
(1) set up your pages for A4 size and - if needed - make sure to print full 
bleed.
(2) program your imposition in PostScript (which is much mor an effort).
