HP Envy 7800 Not Printing Clearly- How to Fix it?

Today I was printing a document on my HP Envy 7800 printer, but it was not printing properly. It is not out of ink, but the printing is missing lines, and the color is off. I don’t know how to fix it. Please help me.

No need to worry, Miss. The printing problem you are facing is because of improper alignment of cartridges during setup.
