When printing slides from Microsoft powerpoint 2007 i get a fine white line at the middle of the page.



I have tried printing it out from Powerpoint 2003 or 2010 there is no problem, but these slides have to be sent out to costumers, and i can't be sure that they aren't using 2007.

I have also tried on to different printers at my workplace, but with no luck.

Hope someone has an idea what might be wrong. - cause I sure don't!

Encountered same problem on b&w printer, not on colour printer.
Solution: white lines on b&w printer disappeared when selecting "High quality" in print window.
