That is true, but I think there are some newer protocols that support higher fidelity.
Also Ubuntu 24.04 LTS (for example) was shipped with pipewire instead of pulse audio which just made the handsfree profile (aka low fidelity bidirectional audio) work out of the box. Have been using it without significant problems since that release.
Out of interest, which printer? Anycubic Kobra by any chance?
Regarding the camera: you could probably script this with ffmpeg and let it output the cropped stream as a virtual camera but I am nog going to pretend this sounds very appealing to most people.
Regarding scanning. Maybe you can scan to PDF and then use this: https://github.com/alam00000/bentopdf . does seem to do OCR also but havent tried it myself.
And wtf is up with that weird queueing mechanism when you're playing an album and want to add some songs to play after that album. You can't append things to your queue in a FIFO fashion
Agreed, a lot of camera's need weird proprietary apps (or cloud connections) to be set up though (or function fully, even offline), thats why I would recommend this. If yours doesnt: great!
Afaik: no
