In Ubuntu 12.04, I added a network printer which I had previously used without any problems on a different machine (with the same release of Ubuntu).
Now, with the default generic driver installed, printing multiple pages per sheet from evince doesn't work properly. If I select 2 per sheet, be it long or short edge, it always prints 4.
Why is this?
It used to happen with non-pdf documents in the past, like from a browser. My workaround was to print to pdf file and then print the pdf itself. Now I'm clueless…
Edit: the same happens with a different network printer, in which I installed the driver specific to its particular model.

Just guessing from sparse / generic information provided, there basically are two places/points worth looking into:
In "Printing" (configure printers, etc), check "page-per-sheet" settings there.
In Evince, again check "page-per-sheet" settings there.
Further, you may want to try printing from yet another application like *office or gedit (and browse their resp. printing options) for comparison and to confine/define the problem.
Good luck ! (with saving paper :)
