Uneven borders when printing

[WordTek]

I tried printing out a page that looked perfect both in document and preview but the border is more slanted to the left leaving the right with more of an open space(about 2 vs 3.3 inches).

So I converted the document into a pdf and although the borders narrowed on conversion they were more even, very slight more open space to the right. here's the current setup:






what could be the problem?
