The first thing you need to do is to avoid MS Works always.
Then you can check that you have the same default paper settings (US letter, legal, A4, B5 or whatever) on both ends.
Next thing to fix is your margins. They're in print preferences in Word, IIRC, and in the page format in Writer.
The last thing you have to do is to accept that results will never be guaranteed to come out the same. Realize that OOo Writer is not MS Word. It will never be. Just like a Hummer vs. a Porsche 930, the performance is somewhat different.
