Question about Brother P-Touch Cube PT-P300BT

At the time of writing: The black one is the 710BT, which can print labels up to 24mm wide. The white one is the P300BT and prints strips up to 12mm wide. There is a white 710BTH, but it does not appear to be on the market at the time of writing.

The white one is rubbish, only runs on batteries and the mains adapter is not included. The black one is great, battery-operated and rechargeable with USB.

Black is more professional
