HP Envy Photo 7155 - Horizontal white lines appear on color prints

[TeamDiaz]

When printing documents with black ink I cannot tell if the lines are visible or not. When printing color prints the lines are visible regardless of the program I use to print such as Adobe Acrobat or Photoshop. The print was purchased only a few months ago.
