The printer is connected to the computer only through a data line. If you connect and disconnect after a while, it can only indicate that the connection of the data line is a problem.Or the USB interface is not well connected, or the quality of the data cable is poor. Turn off the printer and unplug the data cable.Both ends of the computer and printer should be unplugged and reconnected.Or replace the USB interface or the data cable.
What is the configuration? What is the computer? What is the printer? What is the interface? We can judge more accurately. Agree to solve the problem. The system interface contacts the data line to find the problem
There may be a problem with the network card driver or the network card. You can find a good network card and try again. If it doesn't work, kill and kill the virus
