Hi, I’ll be glad to help with the printer issue.
The problem is that the print head is clogged. You can try to run the print head cleaning or get a replacement print head if that does not work.
Your printer should still be under warranty since it has been less than 1 year.
Follow the instructions on this page to clean the print head: http://support.hp.com/us-en/document/c03879639
Most of the time the print head will need to be replaced.
