Why can't the system start after shutdown

[ThinkCodeStudio]

I disable the raspberry PI on the website, and then I disable the printer. Raspberry PI's system won't boot when the printer starts up again

The Raspberry Pi cannot detect the printer powering on. You will need to remove the Pi's power and plug it back in for it to boot up again (this is a Raspberry Pi limitation).

Were you able to solve your issue?

I'm afraid to shut down Raspberry PI right now
