Star TSP143III USB vs Ethernet vs Bluetooth: Which Receipt Printer Is Best?
Choosing a receipt printer sounds simple until the same printer appears in USB, Ethernet, and Bluetooth versions. The Star Micronics TSP143III series offers all three options, and each one is designed for a different type of point-of-sale setup.
The printers share the same basic printing performance. The real decision is how you want your POS system to communicate with the printer.
Quick Answer
Choose the Star TSP143III USB receipt printer if the printer will connect directly to one POS terminal or compatible iPad.
Choose the Star TSP143III Ethernet receipt printer if several devices need to access the printer through a wired business network.
Choose the Star TSP143III Bluetooth receipt printer if you want a wireless connection to a compatible tablet, smartphone, or computer without relying on the business network.
The best option is not necessarily the most expensive one. It is the model that matches your existing POS equipment.

All three are direct thermal POS receipt printers with printing speeds up to 250 millimeters per second, 203 dpi resolution, automatic cutters, and support for 80mm and 58mm receipt paper.
Star TSP143III USB Receipt Printer
The Star TSP143IIIU is the most straightforward option. It connects directly to a compatible POS system through USB, providing a stable connection without requiring network configuration or Bluetooth pairing.
The USB configuration is ideal for:
Single-register retail stores
Reception desks
Service counters
Small restaurants
Businesses using one dedicated POS terminal
Compatible iPad-based checkout stations
Part number 39472310 is the gray USB and Lightning configuration. It includes a USB cable and internal power supply. The Lightning connection can support compatible Apple devices while allowing the printer to serve as part of an iPad POS setup.
A USB receipt printer is usually the best choice when the printer will remain beside one register. It is simple, dependable, and does not depend on the store’s network.
Its primary limitation is flexibility. If several devices need to print receipts through the same printer, an Ethernet model may be more appropriate.
Star TSP143III Ethernet Receipt Printer
The Star TSP143IIILAN connects to a router or network switch through an Ethernet cable. Devices connected to the same business network can send print jobs to it when supported by the POS system.
Part number 39464910 identifies the gray Ethernet configuration and includes the Ethernet cable and internal power supply.
An Ethernet receipt printer is a strong choice for:
Restaurants with multiple ordering stations
Shared retail checkout environments
Businesses with established wired networks
POS systems requiring a network printer
Fixed installations where connection reliability is important
Ethernet offers the convenience of network access without depending on Bluetooth range. A wired network connection is also less likely to experience interference during busy transaction periods.
The tradeoff is setup. The printer must connect to the network, and the POS devices need to be configured correctly. It may require more initial work than plugging in a USB cable, but it provides greater flexibility once established.
Star TSP143III Bluetooth Receipt Printer
The Star TSP143IIIBI2 is designed for businesses using compatible mobile POS devices. It can pair with supported iOS, Android, and Windows equipment without requiring a physical data cable between the printer and the device.
The gray Bluetooth model uses part number 39474710, while the white model uses part number 39474810. Both configurations include an internal power supply.
A Bluetooth receipt printer works well for:
Tablet-based checkout systems
Mobile service counters
Pop-up shops
Events and temporary selling locations
Businesses without convenient network cabling
Small checkout areas where fewer cables are preferred
Bluetooth provides more placement freedom than USB and does not require an Ethernet connection. However, the printer must remain within a practical range of its paired device. Businesses should also verify that their POS software supports the exact Star Bluetooth model before purchasing.
Which Model Is Best for Restaurants?
The Ethernet model is generally the strongest option for a restaurant receipt printer when multiple terminals need to send orders or receipts through the same wired network.
A USB model may be enough for a small café or food counter with one register. Bluetooth can work well for a tablet-based counter, pop-up operation, or mobile checkout setup.
The right answer depends more on the restaurant’s POS system than its menu. Even the best printer becomes an expensive countertop decoration if the software cannot communicate with it.
Which Model Is Best for Retail?
For one fixed checkout station, the USB model provides a simple and stable connection.
For multiple registers or devices operating on the same network, Ethernet offers better shared access. Bluetooth is useful for smaller retail spaces using tablets or mobile POS equipment.
Before choosing, confirm:
Which connections your POS system supports
How many devices will use the printer
Whether the printer will remain in one location
Whether a wired business network is available
Whether your preferred model is supported by the POS software
Final Recommendation
Choose the Star TSP143IIIU USB receipt printer for a single, fixed checkout station that needs a straightforward wired connection.
Choose the Star TSP143IIILAN Ethernet receipt printer when multiple devices need reliable access through an existing business network.
Choose the Star TSP143IIIBI2 Bluetooth receipt printer for compatible tablet and mobile POS systems where wireless placement is the priority.
All three provide similar printing speed and receipt quality. The connection type is what determines which Star Micronics receipt printer belongs in your business.
