Hey There, I am Sofia Carter. If you consistently come across the error message "HP eprint not working" appears, follow the steps below. Make that the printer is turned on and connected to a network with active internet connectivity. Verify that the HP printer enables HP ePrint via email and that the firmware is up to date. Make sure the HP printer's Web Applications are turned on. Check to see whether the printer has been added to HP Connected.
