I solved it with my fork at here: https://github.com/emilmammadov/bluetooth_print You can fork my code but I set the charset to ISO 8859-9 for Turkish characters. So if you will use another charset just change the commit with this SHA 11330f4129e332da772631dc6b62190b152f6955

@thon-ju, can you please add the very simple change from here, essentially just adding the async to your call? https://github.com/emilmammadov/bluetooth_print/commit/68bc24913d0d7c4333dc268e47b8d1e2691da9f4#diff-ae86796ce5471cde755dcbe215a7deb765b7ffdb56671bd2ed4a248f2c7e65d8L23
