the pi connects to the network no problem and the camera is streaming just fine, but i can’t seem to connect to the printer. any ideas? this is what i’m getting…

Connecting to: /dev/ttyAMA0
Changing monitoring state from ‘Offline’ to ‘Error: Connection error, see Terminal tab’
Unexpected error while connecting to serial port: /dev/ttyAMA0 OSError: ‘[Errno 13] Permission denied: ‘/dev/ttyAMA0’’ @ comm.py:_openSerial:1545 (hook default)

Dev/ttyACM0 is what works for me.

Have you tried the usual stuff like unplugging and reconnecting the USB cable, trying a different USB port, toggling power to the printer, etc?
