USB printer support

[timmyhadwen]

Currently this plugin only supports networked printers however the brother_ql library supports USB printers as well. I have tested this by changing the send_label function.

@timmyhadwen interesting, would you be able to submit a PR to provide USB functionality?

I have a fork with just hardcoded values for device address etc. More than happy to complete that implementation with settings etc however just struggling to get the plugin installed in a development environment? Do you have any tips for easy dev of plugins etc? I am currently using Docker and have the plugin cloned into the plugins folder but alas it won't install properly and can't see a nice way to get logs out. Any help or pointing in the right direction would be great :)

If you have the plugin cloned directly into the external "plugins" directory, it won't detect and load, as it is buried too "deep" in the directory structure.

Put the invenrtee_brother subdirectory into the "plugins" directory, and then it should load. Can you check if this works for you?

The easiest thing for me is using devcontainers in combination with editable installs. I described them on the docs a while ago: https://docs.inventree.org/en/stable/develop/devcontainer/?h=devcont#plugin-development

@timmyhadwen did you get it working?

Thanks for your help guys. Work has been busy but hoping to get into a few PRs over the Christmas break. Will update soon.

Hello. I needed the USB connection as well and implemented an additional setting for the plugin. Seems to work fine. You find the changes in my fork, if you're still interested I can create a PR.

@RealNagus a PR would be greatly appreciated!
