use lsusb - find your mainboard ID: idVendor:idProduct
do grep idVendor/idProduct /sys/bus/usb/devices/*/uevent - replace idVendor and idProduct accordingly
note the values of PRODUCT: something like 1a86/7523/264 (these are specific to my mainboard type)
do the command block below that will create a hotplug rule (edit the file after: /etc/hotplug.d/usb/22-tty-symlink after running the below command) and replace PRODID to the values of PRODUCT= from the grep command above. Change SYMLINK name to your likings just don't use spaces.
plug/unplug your printer while on and check if symlink is created inside /dev with ls -l /dev. your SYMLINK name should point to a serial port something like SYMLINK -> /dev/ttyUSB0
inside printer.cfg replace the serial path under [mcu] to /dev/SYMLINK where SYMLINK should be your chosen name OR ttyPrinter (as it is by default)
