Welcome to HP Forums, 

This is a great place to get support, find answers and tips to your technical queries.

I understand that you are in need of support, need not worry I'll be happy to assist you.

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

When was the printer working for the last time?

Have you done any changes on the computer?

However, I suggest you do a Hard Reset

(1) Turn the printer on, if it is not already on.

(2) Wait until the printer is idle and silent before you continue.

(3) With the printer turned on, disconnect the power cord from the rear of the printer.

(4) Unplug the power cord from the wall outlet.

(5) Wait at least 60 seconds.

(6) Plug the power cord back into the wall outlet.NOTE: HP recommends connecting the printer power cord directly to the wall outlet.

(7) Reconnect the power cord to the rear of the printer.

(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.

Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

Then, do reset the printer network settings, complete the following steps:

1. On the printer control panel, touch (Wireless), and then touch Settings. Touch Restore Network Defaults, and then touch Yes. A message appears stating that the network defaults have been restored.

2. On the printer control panel, touch (Wireless), touch Settings, and then touch Print Network &onfigurDtion to print the network configuration page and verify that the network settings have been reset.

Try to connect the printer to the network.
