I noticed that as well, though it was usually not enough to be a problem. Kicad as well as other packages I tried out did not do that, I suspect it is done intentionally with ExpressPCB as they do not really want people printing artwork to self etch boards, notice how it doesn't even let you go to the printer settings.
