I Just want to enquire if someone has had this issue before, if not i'll share the log files and other details
Pi 3B (1.2)
When the machine starts up, the printer lcd screen will continuously refresh/restart. When I disconnect the USB cable at this point, the restarting stops. I'll shut down, remove the USB cable, and start both the PI and the printer.
Once they are both up, I can reconnect the USB cable and all is fine.
Basically the setup does not want to start up with the USB cable connected.
Strange but true
