Bluetooth to printer with Ionic 4

Hi team,
I am relatively new to using native components and have not used bluetooth with Ionic before. I have had a look in the forum and there seems to be a lot of unanswered questions around using bluetooth.

I’m looking at a potential project that would need to use a bluetooth printer with Android and was wondering:

  1. If anyone has done this with Ionic 4 and if so any recommended plugins?
  2. Would the ionic 3 plugins work for this?
  3. Do different printer models require different code or is it a one fits most model?
  4. Is there any way to test this initially without having an actual bluetooth printer?

Any help appreciated!

Cheers,
Mac
