The driver is implemented as a over a hardware abstraction layer (HAL). The stack:

The must implement a reliable ESC/POS-compatible serial interface, real-time status monitoring, automatic cutter control, and thermal protection. The provided architecture and code examples serve as a foundation for embedded Linux, RTOS, or bare-metal integration. For exact timings and command extensions, refer to the official Citizen TZ30 series hardware manual.

class CitizenTZ30: def (self, port="/dev/ttyS0"): self.ser = serial.Serial(port, 115200, timeout=2) self.reset()

If you have an internet connection on the target PC, Windows often has a generic driver built-in.
