Understand the connectivity, printing, paper and application differences before deciding whether the Star TSP100IV X4 or TSP143IIIW better matches your POS environment.

What Is the Difference Between Star TSP100IV X4 and TSP143IIIW? Businesses comparing the Star TSP143IIIW with the newer Star TSP100IV X4 / TSP143IV UEWB may initially see two similar 80 mm thermal receipt printers.

However, the important difference is not simply printing speed.

Both belong to Star's TSP100 family and share several fundamental receipt-printing characteristics, including 250 mm/s maximum print speed, 203 dpi resolution, 80 mm paper support, 58 mm operation with a paper guide, an automatic cutter and an internal power supply.

The major difference is connectivity and the type of POS environment each printer is designed to support.

The TSP143IIIW is primarily a WLAN/WiFi version of the TSP100III generation.

The TSP100IV X4, identified by Star as TSP143IV UEWB, combines Ethernet LAN, USB-C, USB-A, Bluetooth, dual-band WLAN and Star CloudPRNT in one printer.

This makes the comparison particularly relevant when replacing an existing printer, changing POS software, introducing tablets, or moving toward cloud and online-order printing.

What Is the Star TSP143IIIW?

The Star TSP143IIIW is a direct thermal receipt printer from the TSP100III family.

Star identifies the TSP143IIIW as the WLAN/WiFi interface model within that generation.

Current Star EMEA information lists, among others:

39464790 — TSP143IIIW EU + UK Grey

39464890 — TSP143IIIW EU + UK Ultra White

Both are described by Star as thermal printers with futurePRNT, 80 mm paper support, an internal 24 VDC power supply, cutter and WLAN/WiFi interface.

The TSP100III family was designed with separate interface-oriented versions, including USB, Ethernet, Bluetooth and WLAN models.

This distinction is important when comparing it with the TSP100IV X4.

What Is the Star TSP100IV X4?

The Star TSP100IV X4 is part of the newer TSP100IV generation.

Star identifies the wireless X4 configuration as TSP143IV UEWB.

Current EMEA variants include:

39473890 — TSP143IV UEWB Grey E+U

39473790 — TSP143IV UEWB White E+U

Instead of providing only one principal communication interface, the X4 combines multiple wired, wireless and cloud-oriented connectivity options in the same printer.

These include:

USB-C

USB-A

Ethernet LAN

Bluetooth

Dual-band WLAN

Star CloudPRNT

Cash drawer connectivity

The USB-A connection also supports Android Open Accessory (AOA) data communication and charging for compatible Android devices.

How Do Their Connectivity Options Differ?

This is arguably the most important difference.

Star TSP143IIIW

The TSP143IIIW is the WLAN/WiFi model of the TSP100III family.

Star TSP100IV X4

The TSP100IV X4 / TSP143IV UEWB combines:

USB-C

USB-A with Android AOA data and charging support

Ethernet LAN

Bluetooth

Dual-band WLAN

CloudPRNT

This means a business considering the TSP100IV X4 does not necessarily have to choose a separate WiFi, Bluetooth or Ethernet printer variant for those connectivity methods.

Star has incorporated them into the X4 configuration.

Is the TSP100IV X4 Faster Than the TSP143IIIW?

Not according to Star's published maximum print-speed specifications.

Star specifies a maximum print speed of:

TSP143IIIW: 250 mm/s

TSP100IV X4 / TSP143IV UEWB: 250 mm/s

Both also use 203 dpi printing.

Therefore, someone replacing a TSP143IIIW should not assume that the main reason to consider the TSP100IV X4 is higher headline printing speed.

The more substantial change is in connectivity, cloud functionality, device integration and the newer physical platform.

Do Both Printers Use 80 mm Receipt Paper?

Yes.

Both support standard 80 mm thermal receipt paper and can operate with 58 mm paper using the appropriate paper guide.

Star specifies a standard maximum paper-roll diameter of 83 mm for the TSP100 family.

There is, however, a small difference in supported paper thickness.

Star lists:

TSP100III Series: 0.053–0.085 mm

TSP100IV Series: 0.049–0.085 mm

The TSP100IV therefore supports thinner thermal paper within Star's published specifications.

Businesses should still verify the actual paper specification required for their application rather than selecting receipt paper solely by width.

Does the TSP100IV X4 Support WiFi?

Yes.

The TSP100IV X4 includes dual-band WLAN, supporting both 2.4 GHz and 5 GHz wireless connectivity according to Star's current specifications.

Star also identifies WiFi 6 and WPA3 in the current TSP143IV X4 specification sheet.

Star provides wireless setup methods including an automatically generated QR code and the Star Quick Setup Utility.

The TSP143IIIW also provides WLAN connectivity, but it belongs to the earlier interface-specific TSP100III architecture.

Does the TSP100IV X4 Have Ethernet?

Yes.

Ethernet LAN is integrated into the TSP100IV X4 alongside its wireless interfaces.

This is a meaningful difference from the TSP100III family structure, where Star offered separate interface models such as:

TSP143IIIW — WLAN

TSP143IIILAN — Ethernet

TSP143IIIBI — Bluetooth

The TSP100IV X4 consolidates Ethernet, WLAN and Bluetooth connectivity into a single configuration.

This can provide more flexibility if a POS environment changes its preferred connection method later.

Does the TSP100IV X4 Support Bluetooth?

Yes.

Bluetooth is included with the TSP143IV UEWB / TSP100IV X4.

By comparison, Bluetooth within the TSP100III generation was associated with the TSP143IIIBI variant rather than the TSP143IIIW WiFi model.

Again, this demonstrates one of the principal architectural differences between the generations: the X4 brings several connectivity methods together.

What Is Different About USB Connectivity?

The TSP100IV generation introduces more flexible USB connectivity.

The TSP100IV X4 includes:

USB-C

USB-A

The USB-A port supports Android Open Accessory (AOA) communication and charging for compatible Android tablets and mobile devices.

It can also support compatible USB peripherals such as scanners or displays in appropriate configurations.

Compatibility should nevertheless be confirmed for the particular POS device, operating system, application and peripheral combination being considered.

A physical USB connection alone does not guarantee software compatibility.

What Is CloudPRNT?

Star CloudPRNT is technology designed to enable supported web- and cloud-based systems to communicate with compatible Star printers.

The TSP100IV family includes Star CloudPRNT technology for online receipt and order printing.

This can be relevant to businesses using:

Online ordering

Web-based POS systems

Cloud applications

Hospitality ordering platforms

Remote order workflows

However, an important distinction should be understood:

Having CloudPRNT support does not automatically make the TSP100IV compatible with every cloud POS, e-commerce or online-ordering platform.

The software platform must support an appropriate integration method.

Always verify software compatibility before selecting hardware for a cloud-printing project.

Can the TSP100IV X4 Work with Android POS Devices?

Star provides Android-oriented functionality through the printer's USB-A Android Open Accessory support, including data communication and charging for compatible Android tablets and mobile devices.

Star also provides software resources including StarXpand SDK and StarPRNT SDK for supported platforms.

This does not mean every Android tablet or every Android POS application will automatically work with the printer.

Before ordering, verify:

Android device model

Android version

POS application

Required connection method

Printer driver or SDK requirements

Charging requirements

Peripheral requirements

This is particularly important when replacing an existing printer in a functioning POS environment.

Is the TSP100IV X4 Smaller Than the TSP100III Generation?

Yes.

Star states that the TSP100IV is approximately 20% smaller than TSP100III models.

The TSP100IV X4 measures approximately:

140 mm (W) × 169 mm (D) × 123 mm (H)

Weight: approximately 1.3 kg

It retains an internal power supply and supports horizontal, vertical and wall-mounted operation.

This can be useful where counter space is limited.

Is the TSP100IV X4 a Direct Replacement for the TSP143IIIW?

It should not automatically be treated as a universal drop-in replacement.

From a receipt-printing perspective, there are significant similarities:

203 dpi resolution

250 mm/s maximum print speed

80 mm thermal paper

58 mm paper capability with guide

Automatic cutter

Internal power supply

But replacement suitability also depends on the existing POS environment.

Before changing from a TSP143IIIW to a TSP100IV X4, verify:

POS software compatibility

Operating system

Printer drivers

Existing WLAN configuration

Receipt formatting

Application-specific printer settings

Peripheral connections

Cash drawer requirements

API or SDK dependencies

Cloud-printing requirements

Physical installation

A newer printer having more interfaces does not guarantee that existing software will recognize or configure it identically.

Is the TSP143IIIW Discontinued?

NEOTECH® does not currently recommend making that blanket statement based on the information reviewed for this article.

Star's current EMEA TSP100 information continues to list the TSP143IIIW EU/UK grey 39464790 and ultra-white 39464890 variants.

Interestingly, the same current Star material explicitly labels the grey TSP143IIILAN as discontinued and points users toward TSP143IV UE, but it does not provide the same explicit discontinued wording for TSP143IIIW in the information reviewed.

For that reason, customers should verify current regional availability rather than assuming lifecycle status from third-party listings.

Which Printer Should a Business Consider?

Neither printer should be selected simply because one model is newer.

The TSP143IIIW may remain relevant when:

An existing system already uses it successfully.

The required connection is WLAN.

Existing software specifically supports the TSP143IIIW.

There is no operational reason to change a functioning installation.

The TSP100IV X4 may be worth considering when:

Multiple connectivity methods are useful.

Ethernet and WiFi flexibility is required.

Bluetooth is required.

USB-C connectivity is relevant.

Compatible Android data-and-charge functionality is useful.

CloudPRNT functionality is required.

A new POS deployment is being planned.

Future changes in POS connectivity are anticipated.

The correct decision depends on the complete POS ecosystem, not the printer specification alone.

What Should You Verify Before Changing Your POS Printer?

Before replacing a TSP143IIIW—or any existing receipt printer—confirm:

Exact existing printer model and part number

Do not rely only on the appearance of the printer.

POS software

Confirm that the application supports the proposed printer.

Operating system

Check the required Windows, macOS, Linux, Android or other platform support.

Connection method

Determine whether the installation requires WiFi, Ethernet, Bluetooth or USB.

Network requirements

Check WLAN bands, network security and configuration requirements.

Receipt paper

Verify width, thickness and roll dimensions.

Cash drawer

Confirm electrical and connector compatibility rather than assuming that every similarly shaped connector is interchangeable.

Other peripherals

Check customer displays, scanners, buzzers and other attached equipment separately.

Cloud integration

CloudPRNT capability should be verified against the actual software platform.

Regional SKU

Confirm that the exact part number is appropriate for the intended market, power requirements and supplied accessories.

Why Does NEOTECH® Recommend Compatibility Verification First?

A receipt printer is only one component of a POS system.

Two printers may use the same 80 mm paper and offer similar printing speeds while behaving differently when connected to particular software, operating systems, networks or peripherals.

For that reason, NEOTECH® encourages businesses to identify their actual requirement before purchasing or replacing POS hardware.

Learn First. Decide Second. Buy Only If It Is Right for Your Needs.

There is absolutely no obligation or pressure to proceed with a purchase from NEOTECH®.
