Printer Disconnects Mid Print

What is the problem?

If I have any plugins installed, or try to print not in safe mode, my printer disconnects midway through the print and the print fails.

What did you already try to solve it?

New Pi, fresh install, nothing plugged into pins, new power adapter, new USB to printer

Have you tried running in safe mode?


UPDATE 6/3: It is now failing even in safe mode

Did running in safe mode solve the problem?

Only prints in safe mode

What printer do you use? I do not find any information on it.

As for the log, the printer stopped communicating:

Is this a new development from your previous thread? Did the new power adapter not make it work?

It did for a day or two, and then it started crashing again. I just had it crash while printing in safe mode
