@PragmaticBody, Welcome to the HP Support Community!
This is really bizarre indeed. Make sure the printer is connected to a secure network so that no one else can control the printer like on an open network.
Reset the printer
- With the printer turned on, disconnect the power cord from the rear of the printer.
- Wait at least 60 seconds.
- Reconnect the power cord to the rear of the printer.
- Turn ON the printer, if it does not automatically turn on.
- 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.
Update the printer firmware

Monitor the printer. If the issue persists, we will have to perform a factory reset on the printer. This will delete all the settings on the printer.
- I've sent you a private message with reset instructions, follow the reset instruction to perform a full reset and re-initialize the printer.
