I have a new printer. I set it up a couple of weeks ago, and used it. Now it is asking for a password. I didn't need the password before and I don't know it. How can I solve this?

Thank you for joining HP Forums.

It's a pleasure assisting you in finding answers to your technical queries.

I understand that the printer was working before, now when you try to print its prompting for a password, need not worry I'll be glad to assist you.

To provide you with an accurate solution, I'll need a few more details:

How is the printer connected? (USB or Wireless)

Make sure that the printer is connected to the network. (If wireless)

Can you make a copy?

If the printer is connected wirelessly, Could you check for WiFi interference and also perform a ping test using the Mac Network Utility and let me know the results. Use the printer IP address to perform a ping test, the printer IP can be located by touching the wireless icon on the printer display.

Meanwhile, update the printer firmware and Mac software:

Update printer firmware

Update software on Mac 

Keep me posted, how it goes!

Have a great day!

Cheers:)
