Welcome to the HP support community.

I understand that you are getting print quality issues, I am glad to assist you.

Did you make a copy and check if that prints fine?

Meanwhile:-

Print a Print Quality Diagnostic Page

1. Load plain white paper in the input tray.

2. From the printer control panel, open the Setup  menu.

3. Open the Reports or Tools menu.

4. Touch Print Quality Report.

If that does not print fine, follow these steps to fix the issue.

Clean the printhead

1. From the printer control panel, open the Setup  menu.

2. Open the Printer Maintenance menu.

3. If necessary, open the Tools menu, and then touch Clean Printhead.

Today while browsing in the printer menu i came across Demo Page. I printed it and is perfect, no lines WoW I thought my problem was solved so i placed a photo in the scanner and white lines all across it. I printed a photo from the smart app and still white lines all across photo.  I have unplugged printer overnight, cleaned 4 times, aligned twice, changed cartridges, and even cotton swabbed.    What to do?

It did not help. Print Quality page was good. But when I print in color with some photos after about the 3rd of 14 pages I'm printing I start getting lines in the photos
