@Renieike, Welcome to the HP Support Community! I’m here to help.

I see that the printer display screen is not responding to the touch. Check for any damage to the display.

Reset the printer

1. With the printer turned on, disconnect the power cord from the rear of the printer.
2. Wait at least 60 seconds.
3. Reconnect the power cord to the rear of the printer.
4. Turn ON the printer, if it does not automatically turn on.
5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

If this does not help, unplug the power cable and hold the power button down for 10-15 seconds and release it. Power on the printer and check.

Update the printer firmware

If the issue persists, I'm afraid this is a hardware failure. If the printer is out of warranty, I suggest you upgrade the printer. You may visit Hp Store to check the available printers.

This model printer does not have a Bluetooth feature. Are you referring to Wireless? The blue antenna icon?

If this is not illuminated, it means the wireless radio is off. We can turn it on only if the touch screen is working. You may still use a USB cable between the printer and the computer and try printing.

Keep me posted for any other assistance.
