[FR] Add asynchronous printing progress bar

Problem statement

This error has come up several times now, so I created an issue for it to track it:

When printing using asynchronous printing mechanisms (that do not directly return a file), printing works, but the following error is shown along a success message:

Error: The label could not be generated

Suggested solution

Implement a progress bar in the notification, which updates and resolves when printing is done.

That would be great, good FR @wolflu05 !

This would be great. With the same mechanism we can finally also offload report generation to the background process (and show progress in the UI).
