Print differs from print preview & what is printed on another printer.

Hi
I am printing name tags just in a two column Word document (Word 2002). On Print Preview they are perfect & when I print using my Samsung Laser, but when I print the same document on my hp psc 1350. They are about 1/3 the size smaller with a really wide margin on the left & on the bottom. What is making them print smaller & in the top right hand corner on this printer & how can I get them to print correctly?
