If there is an electrical appliance that leaks electricity and grounding in the kitchen, find an electrician to check it carefully.
According to your description, it may be that there is a problem with the printer interface or the corresponding computer interface, you may use other cables to try these two interfaces to determine if there is a problem with these two interfaces. Since I'm not very professional in this either, I've only thought of this method, and I hope it will be useful to you.
The square wire is enough for a single wire, and the ordinary socket is bought with 5 holes and 10A. Directly to the shunt switch, (L to the live wire, N to the zero wire, and one is the grounding wire) 3 one way, the air conditioning socket is 16A. The mechanical and electrical wiring of the large cabinet should be replaced with a thickness of more than 4 square meters. >>>More
Turn off the kitchen lighting and socket first, unplug the electrical appliances, and observe the power transmission.
If there is no corresponding kitchen shunt leakage and air switch, it will definitely affect the total power supply of the whole building!
