Citizen receipt printer (model: CT-S251). Items for sale: * Main unit * Power cable * USB connection cable, approx. 2m * Cable cover (already attached to the main unit) * Used roll paper (width 58mm, diameter approx. 31mm) The interface is USB + Bluetooth (see image 5). The memory switch settings have been initialized. There is no outer box or instruction manual. There are no noticeable scratches, stains, or damage on the main unit, but there are some minor scuff marks. I have confirmed that it is recognized by my PC (Windows 10) when connected via USB cable, and that Bluetooth is recognized by my smartphone. I have also confirmed that test printing and cutting operations are working correctly (see image 6). I will carefully clean and pack it with消毒用アルコール (disinfecting alcohol).
