Error on Printing PowerPoint presentation

I need to print a PowerPoint presentation on Wednesday. I used Templates then type my slide text in the pre-set boxes. Everything is working fine, but when I print it there are changes into it. The headline text displays on the darker box with the same size as the body text boxes. The font becomes white with blue background. That background becomes a darker blue and is outlined by the shape of the picture box. I don’t know what happens but I need to fix it as soon as possible. How can I print it with the correct color and shapes? Help please.
