HP Envy 7640 prints horizontal lines when printing photos

[RWAKSA]

I have attempted to print photos on my printer and continue to get horizontal lines across the photos that are approximately 3/4 inch apart.  I have ran all of the printer diagnostic tools. I am printing from a MAC. 

Thanks.

It appears to be the photo paper that I was printing on.  It is glossy Kodak Photo Paper.  Thank you for your assistance.
