1. Overview The Citizen TZ30-M01 is a high-speed, direct thermal printer mechanism designed for integration into kiosks, POS systems, ticket validators, and medical devices. It features a 3-inch (80mm) print width, auto-cutter support, and low-voltage DC operation. This document outlines the driver architecture, control logic, and hardware abstraction for the mechanism.
