I need to print some mathematical articles. But the margin is too large, so I want to edit it to solve this problem.

One way is converting it to Microsoft Word (I think). But I tried some programs and they give very bad conversions.

How would you solve it? I am sure that some of you encounter this problem regularly.

editorought to have a cropping function... – J. M. Jul 30 '11 at 3:46
