Welcome to the HP Forums :) I would like to take a moment and thank you for using this forum, it is a great place to find answers.
Before we get into troubleshooting, I would like to ask you a few questions to get a clear picture of what's going on with the Printer.
From where are you printing? What is the operating system installed on the Computer/phone to which the Printer is connected to? if you're trying to print to a Computer/phone that is.
Let us know :)
