The customer uses an industrial touch screen, which automatically sends a debug to the printer every time the device is turned on. This causes the printer to automatically print a series of system information every time the device is turned on. By using the printer's unique function of powering off the default port, the problem of automatic sending of control end data to the serial port and printing is solved. Combined with the command to open the serial port of the printer, after normal startup, the printer can communicate and receive printing data normally by sending the open serial port, thereby avoiding the bugs inherent in the control end device's serial port.
