Printer doesn't connect automatically when printer starts up

What is the problem?

Auto-connect on server startup doesn't work

Here is the log from the terminal tab:

Changing monitoring state from "Offline" to "Opening serial connection"
Connecting to port /dev/ttyUSB0, baudrate 115200
Changing monitoring state from "Opening serial connection" to "Error"
Changing monitoring state from "Error" to "Offline after error"
Unexpected error while connecting to serial port /dev/ttyUSB0, baudrate 115200 from hook default: SerialException: '[Errno 2] could not open port /dev/ttyUSB0: [Errno 2] No such file or directory: '/dev/ttyUSB0'' @

thanks for your help in advance


  • What happend to the template when you opened this thread?
  • Have used the link in the error massage?

Are your port and baud rate parameters set statically? If so, check to see if the printer's speed has changed, and verify that /dev/ttyUSB0 is the correct port.

If they're not set statically, then set them!
