Star Micronics TSP143III Thermal Receipt Printer for POS Systems
The Star Micronics TSP143III, part of the Star TSP100III family, is a proven 80mm direct thermal receipt printer widely used in retail, restaurant, hospitality, and tablet-based POS environments.
Important: TSP143III models were sold in several different interface configurations, including USB, Ethernet/LAN, Bluetooth, and wireless versions. These interfaces are not interchangeable. Before ordering, verify the exact Star part number, interface, and POS software requirements for the printer you need.
Quick Answer
Choose the Star TSP143III when you need a dependable 3-inch thermal receipt printer and your POS system specifically supports the TSP100III generation. If you are installing a new system or replacing an older TSP100/TSP143III, consider the newer Star TSP143IV generation as the current upgrade path.

Choose the Correct TSP143III Interface
One of the most common buying mistakes with the TSP143III is assuming every version supports the same connection method. The interface is determined by the exact Star model.
- USB: Typically used with a directly connected Windows, Mac, or supported tablet POS station
- Ethernet / LAN: Connects the printer to the local network
- Bluetooth: Common in compatible mobile and tablet POS environments
- WLAN / Wi-Fi: Used when supported wireless network printing is required
Do not select a printer based only on the TSP143III name. Match the complete Star part number to the interface required by your POS software.
POS Software Compatibility
The TSP143III family has been used with a wide variety of POS applications, but hardware compatibility does not guarantee software compatibility. Your POS application must support the exact printer model and interface you purchase.
If you are replacing an existing Star printer, the safest method is to locate the Star model or part number on the label of the existing printer and match its interface before ordering.
TSP143III vs. TSP143IV
The Star TSP143IV is the newer generation of the TSP100 platform and is designed to make replacing older TSP100-series printers easier. It adds more current connectivity and cloud-oriented capabilities while retaining the familiar 250 mm/sec thermal printing platform.

|---|---|---|
| Generation | TSP100III | Current TSP100IV generation |
| Print Speed | Up to 250 mm/sec | Up to 250 mm/sec |
| Interfaces | Interface-specific models | Newer multi-interface configurations available |
| Cloud Features | Depends on model/application | Expanded CloudPRNT / cloud capabilities |
| Best Choice | Existing TSP143III installations | New installations and upgrades |
Replacing an Older Star TSP100 Printer?
If you currently have a TSP143III and need an exact replacement, first identify its complete model and interface. If your POS provider supports the newer generation, the TSP143IV is generally the better long-term upgrade path.
