Thank you for posting on HP Forums,
The Barachiel is at your service.
I understand you are in need of support,
I'll be glad to help you out, however, for an accurate solution I will need more details:
Have you attempted any steps on your own before posting on the HP Forums?
When was the last time it worked without these issues?
In the meantime, please try the steps mentioned below:
Remove the cartridges fro the printer. Turn it on and then follow the steps given below to perform a reset.
Once done, put the cartridges back and try to print. 
follow these steps to reset the printer.
Turn the printer on, if it is not already on.
Wait until the printer is idle and silent before you continue.
With the printer turned on, disconnect the power cord from the rear of the printer.
Unplug the power cord from the wall outlet.
Wait at least 60 seconds.
Plug the power cord back into the wall outlet.
NOTE:
HP recommends connecting the printer power cord directly to the wall outlet.
Reconnect the power cord to the rear of the printer.
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.
Please reply with the details for further assistance.
Eager to help!
