Continuous light streaking even after all troubleshooting

[Pringles8605]

Even after much repeated trouble shooting, cartridge cleaning, printhead cleaning, aligning, and new cartridges, there continues to be faint streaking across the page creating horizontal stripes about every 1.5 cm spanning the height of any solidly printed image.  HP's instructions even include a photo (below) of what my page looks like if the printer is working properly...but a properly printed image should be a complete image without streaks, correct?  Anyone else experiencing this and know how to fix it?  Or did I just purchase a lower-quality printer?

Try making a standalone copy and check if that prints fine. By this, we can conclude if this is a hardware or a driver issue.

If the copy also has horizontal lines, this could be a hardware issue.

If you have tried the steps mentioned in this document - Black or Color Ink Not Printing, Other Print Quality Issues, and the issue persists, please reach out to the HP Support in your region regarding the service options for your printer.
