I succed printing on the device on Kitty printer from my phone and from the PC but only on windows. This the same PC on Ubuntu it's not possible to print with Kitty-printer

Made it work. You need to do 2 things, enable experimental in systemd and experimental in chrome:

To enable experimental Bluetooth D-Bus interfaces, you can modify the Bluez service configuration by adding the --experimental flag to the ExecStart line in the bluetooth.service file.
For example:

[Service]
ExecStart=/usr/libexec/bluetooth/bluetoothd --experimental

After making this change, reload the systemd configuration and restart the Bluetooth service:

sudo systemctl daemon-reload
sudo systemctl restart bluetooth

If you are using a version of Bluez lower than 5.43, you may need to run the Bluetooth daemon with the -E flag to enable experimental interfaces.
However, this is typically handled through the service configuration rather than directly invoking the daemon with the -E flag.

For Web Bluetooth to work in Chromium, you also need to enable the

chrome://flags/#enable-experimental-web-platform-features

flag.
This flag allows the browser to access experimental web platform features, including Web Bluetooth.
