We've got a self-built mobile device which can transfer data via Bluetooth SPP to a PC. On the market there are numerous devices acting as mobile printers via Bluetooth. Some of them use a custom ASCII-based printing language, e.g. the label printers from Zebra.
So there is the idea of printing via SPP from our device. Sadly there is not too much usable information on the internet on this special topic.
Can you recommend any printer (at least A4) capable of printing via Bluetooth SPP with publicly available protocol specs? Or do you have any hints where to start?
