White line at print - not in pdf or indesign

Hi there

I am a newbie with indesign, but still managed to create a cv. However, when I print, it creates a white line at the right margin, that is not shown in indesign or in the pdf reader. I have circled the line from the show print screen at the pdf reader - you can see it here: http://imageshack.us/photo/my-images/833/whybv.png/  what can the problem be?

Thanks in advance...
