Hello Cynthia,
I understand that you cannot print coupons poperly because of the ads that you are seeing on your account. Let me further assist you with your concern.
If you check the buttons on your screen, you will be seeing three buttons on the right part of the message that looks like the image below:

Click on the third button (one that is encircled) and the ads that you are seeing on the right column will be temporarily hidden. Also, double clicking on the message will give you full view of the message. How are you printing the coupons from your Inbox?
Ads should not be included on the hard copy and you should only see the email content itself.
I hope that this was helpful.
Thank you.
