NB: During Bluetooth communication, if you transfer 1 MB or more of printing data, the buffer will overflow, and the data may not be printed properly. There are also known Bluetooth connectivity issues when running the Spotify App with AirPOS. Attached Bluetooth peripherals (Card Readers, Printers, Barcode Scanners, etc) may regularly drop connection resulting in receipts not printing, drawers not kicking and aborted card transactions.
