My HP sprocket recently started printing out pictures with very visible lines across ithe image I think it's skipping when it prints so the quality comes out really bad. It was fine before but all of a sudden something it started printing weird. I reset it and used the blue paper but still not working.
Note: I suggest that you check the steps under the sub-link "what can I do to improve print quality?" in the above document.
