Multi-Connectivity POS Receipt Printer

One of the most important characteristics of 39473890 is connectivity.

The TSP143IV X4 provides several interfaces within the same printer:

USB-C

USB-A

Ethernet LAN

Wi-Fi

Bluetooth

CloudPRNT

This can be useful where businesses need flexibility in how the receipt printer connects to current and future POS equipment.

However, having an interface on the printer does not automatically mean that every POS application supports that connection method.

POS software compatibility should always be verified before ordering.

Dual-Band Wi-Fi

The TSP143IV X4 supports wireless LAN connectivity across 2.4 GHz and 5 GHz bands.

Star's current specifications identify Wi-Fi 6 and WPA3 support.

Wireless printing can be useful where a physical Ethernet connection is inconvenient or where the POS environment has been designed around compatible wireless devices.

Star also provides setup functionality intended to simplify WLAN configuration, including its Quick Setup Utility.

Bluetooth Connectivity

Bluetooth provides another wireless connection option for compatible POS and mPOS applications.

This can be useful in tablet-oriented environments where the selected application specifically supports the Star printer and its Bluetooth interface.

Again, Bluetooth availability should not be interpreted as universal software compatibility.

The operating system, POS application and printer connection method should be checked together.

Ethernet LAN

For businesses preferring a wired network connection, the TSP143IV X4 also incorporates Ethernet LAN.

Ethernet can be relevant for fixed POS installations where a stable wired network connection is preferred.

Having both Ethernet and wireless connectivity gives businesses additional flexibility when planning or modifying the POS environment.

USB-C and USB-A

The TSP143IV X4 provides both USB-C and USB-A connectivity.

Star also identifies Android Open Accessory support through USB-A for compatible Android tablets and mobile devices, including direct communication and charging functionality.

This can make the printer relevant for Android-based mPOS installations where the complete hardware and software configuration has been verified for compatibility.

What Is Star CloudPRNT?

Star CloudPRNT is designed to allow compatible cloud and web-based applications to communicate with supported Star printers for remote receipt and order printing.

This can be relevant for workflows such as:

Online orders

Cloud-based POS

Web ordering

Remote order printing

Hospitality ordering

Click-and-collect workflows

CloudPRNT support does not mean that every website or cloud POS system will automatically print to the TSP143IV X4.

The software platform must support the appropriate Star integration. Star identifies the TSP100IV family as cloud-ready through CloudPRNT technology.

250 mm/s Thermal Printing

The TSP143IV X4 has a specified maximum print speed of 250 mm per second.

Direct thermal printing means that normal receipt printing does not require an ink cartridge or toner cartridge.

Instead, the printer uses compatible thermal receipt paper.

This makes it suitable for transaction environments where regular receipt printing is required.

80 mm and 58 mm Paper

The printer is primarily designed for 80 mm thermal receipt paper.

It can also accommodate 58 mm paper using the included paper guide.

The appropriate paper width should be selected according to the POS application, receipt layout and business requirements.

For normal operation, use thermal paper meeting the printer manufacturer's applicable specifications.

Compact Installation

The printer measures approximately:

Width: 140 mm

Depth: 169 mm

Height: 123 mm

Weight: 1.30 kg

It can be operated:

Horizontally

Vertically

Wall mounted

The power supply is internal, reducing the need for a separate external power brick around the POS counter.

Applications

The Star TSP143IV X4 may be considered for:

Retail POS

Restaurants

Cafés

Hospitality

Supermarkets

Convenience stores

Pharmacies

Specialty retail

Service counters

Reception environments

Tablet-based mPOS

Android POS systems

Cloud POS applications

Online-order printing

Click-and-collect workflows

Kitchen or order receipt workflows where the application and environment are suitable

The printer should be evaluated according to the actual POS software and connection requirement.

Purpose of Use

The TSP143IV X4 is intended to provide businesses with a flexible thermal receipt-printing platform that can accommodate both traditional and newer POS architectures.

Rather than purchasing separate printer configurations simply to obtain different interfaces, 39473890 combines USB, Ethernet, Wi-Fi, Bluetooth and cloud connectivity within one model.

This may be particularly useful where a business expects its POS environment to change over time.

Compatibility

Before purchasing, verify compatibility with:

POS software

mPOS application

Windows environment, where applicable

Android POS application

Tablet or mobile device

Ethernet network

Wi-Fi network

Bluetooth connection method

Cloud-based POS platform

CloudPRNT integration

Cash drawer

Customer display

Barcode scanner

Receipt width and layout

Required printer drivers or SDK

Compatibility is especially important when replacing an older Star printer.

Replacing an Older Star TSP143III Printer

The TSP143IV X4 is a newer-generation Star receipt printer, but customers replacing an older TSP143III, TSP143IIIW or another legacy Star model should not assume automatic software compatibility.

The physical printer may be newer and offer additional connectivity, but the existing POS application must still support the required printer model, driver, interface or emulation.

Before replacing an older printer, verify:

Exact existing Star model

Existing connection method

Operating system

POS software

Printer driver

Receipt configuration

Cash drawer connection

Any application-specific printer integration

This check is especially important for older POS software that may have been configured specifically for a previous Star model.

Compatible Accessories

Star identifies several accessories for the TSP100IV ecosystem, including:

Star SCD222U Customer Display

Star mC-Sound MCS10

Star BU01 Buzzer

Star Cash Drawers

Star Barcode Scanners

Star mUnite Tablet Stands

Accessory compatibility should be verified against the exact installation and part number before ordering.

What's Included

Star's TSP143IV X4 documentation identifies the following with the printer:

Power cable

USB A-to-C cable

58 mm roll-paper guide

Rubber feet

Easy Setup Guide

Package contents can vary by region or supply channel, so the actual quotation should be checked before ordering.
