Description

• How to install and print on a Thermal Printer USB 58mm / 80mm. https://twitter.com/juancarlospaco/status/1128781387782344710/photo/1 https://twitter.com/juancarlospaco/status/1128732835131678720/photo/1

Why?

• This kind of printer is cheap as hell compared to all other kind of printers, including ink-tank and dot-matrix.
