Hotplug hack

On host machine:

Create reload.sh with content:

#!/bin/bash

docker-compose -f <path to>/docker-compose.yaml  stop
docker-compose -f <path to>/docker-compose.yaml up -d

Run

sudo chmod +x reload.sh

Run

udevadm monitor --kernel --property --subsystem-match=usb

Connect your printer, you should see something like this:

monitor will print the received events for:
KERNEL - the kernel uevent
KERNEL[6147.486744] add /devices/pci0000:00/0000:00:0c.0/usb1/1-2 (usb)

Edit file /etc/udev/rules.d/test.rules Add:

ACTION=="add", SUBSYSTEM=="<<copy_subsystem>>", ENV{PRODUCT}=="<<copy_product>>", RUN=="/bin/bash <path to>/hotplug.sh"

not sure if neede -- udevadm control --reload

Inside docker container

Create /hotplug.sh

#!/bin/bash

sleep 2
cat /usr/share/foo2zjs/firmware/sihp1020.dl > /dev/usb/lp0

Run

chmod +x /hotplug.sh

edit /entrypoint.sh and add to second line

./hotplug.sh
