Doesn't print right side of page

I think I've asked this before but I'm not certain so I'll ask again just to get sure. Sorry, if you have already answered me in a previous post. So, after beta 1 every time I try to print a score created with MuseScore, my printer doesn't print a part of the right (the way I see it) side of the page. This is the part that includes the side barlines and the end of the composer's name. I guess it's a bug, 'cause I tried in a friend's printer andthere's the same problem. Please fix it if you can before 2.0. Thanks in advance!
