Hello
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I noticed your post about your Deskjet 5525 showing print quality issues when it prints. I would suggest troubleshooting the issue by following the steps in the guide below.
I hope this helps!
Fixing Ink Streaks, Faded Prints, and Other Common Print Quality Problems
If the troubleshooting does not help resolve your issue, I would then suggest calling HP's Technical Support to see about further options for you. If you are calling within North America, the number is 1-800-474-6836 and for all other regions, click here: http://www8.hp.com/us/en/contact-hp/ww-contact-us.html
