I signed up for Airレジ (Air Register) about 5 years ago, but this printer was only used a few times. It was able to print. It has been stored in a dark place since then.
Since I am no longer using Airレジ (Air Register), I cannot perform test printing with the unit alone.
Charging confirmed via micro USB cable (Type B). The power turns on. Please see photos. The power lamp is on.
Paper also comes out.
Printing functionality has not been confirmed.

It can be charged with a standard micro USB cable (Type B).
Everything shown in the images is included.

Will ship via either YuYu Mercari便 or RakuRaku Mercari便.
