According to the manufacturer, thermal paper must be used. Unfortunately, the number of prints after which the product must be replaced is not specified.

Normally it is this charger: Brother PA-AD-600EU And in addition to this, you need the power cable. I couldn't tell you which one, but if you look at the port, it should be a C5, C7 or C13, for example: https://www.digitec.ch/Comparison/6147252-6898707-12364041
