POS printer Star Micronics TSP143IV UEWB GY Direct thermal 250 mm/sec Wired Wireless

The Star Micronics TSP143IV UEWB GY is a compact direct thermal POS printer offering 250 mm/sec printing speed and multiple built-in connectivity options. Designed for countertop or vertical mounting, the grey TSP143IV combines a small footprint, an integrated power supply and paper-saving features with support for iOS, Android and Windows devices. Star’s CloudPRNT Next using MQTT is included for reliable cloud-to-device communication.

Advantages

The printer provides all-in-one connectivity with four integrated interfaces: USB, Ethernet LAN, Wireless LAN (dual-band 2.4/5 GHz) and Bluetooth, plus AOA over USB-C for wired communication and charging with supported Android devices. Fast direct thermal printing at 250 mm/sec, thin paper support and an on-model warranty period of 4 years add to operational reliability. Dual-band WLAN enables automatic selection between 2.4 GHz for range and 5 GHz for lower congestion, and a simplified WLAN setup with diagnostic printouts confirms successful configuration.

Recommendations

Use recommended direct thermal paper in the correct width and avoid prolonged exposure of printed receipts to heat or sunlight. For stable wireless performance, place the printer within good signal range of the Wi‑Fi access point and choose 5 GHz where interference is an issue or 2.4 GHz when longer range is required. Keep firmware and drivers up to date to ensure CloudPRNT and network features operate correctly.
