TSP143IV SK Sticky Linerless Label Printer
Introducing the TSP143IV SK series from Star Micronics: the pinnacle of thermal linerless removable label printing in a sleek, compact form. As the market’s smallest 3-inch desktop sticky label printer, it blends advanced features like Android Open Accessory (AOA) support, dual-band wireless connectivity, and CloudPRNT Next technology with eco-friendly linerless labels. Ideal for a variety of applications, from food and beverage service (QSR) to delivery, this printer enhances efficiency with its repositionable labels that adhere to any surface without leaving residue. The TSP143IV SK is a step forward in printing technology and environmental responsibility, making it a perfect fit for modern businesses.
The TSP143IV SK series supports linerless label printing for QSRs, cafes, delis, and online ordering environments. Compatible with Star Blue Eco linerless labels, these Prop 65-compliant labels are formulated without bisphenols and support food labeling, drink labeling, and order handoff workflows. Repositionable adhesive helps labels stay attached to cups, containers, and bags while removing cleanly. By eliminating silicone liner backing, businesses can reduce label waste and keep prep stations cleaner.
CloudPRNT Next uses MQTT technology to improve communication between cloud applications and label printers. Orders and print jobs can be sent directly from online ordering platforms without requiring a local tablet, PC, or middleware device. Real-time status updates and efficient data transfer make it well suited for QSRs, retail stores, and multi-location order fulfillment.
The TSP143IV SK X4 combines USB-C, Ethernet, WLAN, and Bluetooth in a single linerless label printer, reducing the need for multiple interface-specific models. Support for Windows, iOS, and Android devices makes it easy to deploy across POS, mobile POS, and cloud-based ordering environments. USB-C also supports data and power delivery for connected devices.
The TSP143IV SK X4 features Star’s Ultra-C USB-C connectivity, supporting power and data communication with iOS, Android, and Windows devices through a single connection. Android Open Accessory (AOA) support enables compatible Android devices to communicate directly with the printer while receiving power, helping reduce cables, power adapters, and connection points in modern POS and mobile ordering setups.
The TSP143IV SK X4 supports both 2.4GHz and 5GHz Wi-Fi for flexible wireless deployment. rapidSYNC, Star’s easy BLE-assisted Wi-Fi setup, simplifies onboarding through the Star Quick Setup Utility, while diagnostic printouts help confirm a successful connection. The printer can also connect USB peripherals such as barcode scanners and displays, supporting streamlined POS and labeling setups in retail, restaurants, and other fast-paced environments.
The TSP143IV SK is 20% smaller than previous models, helping free up counter space in busy POS and prep environments. Its internal power supply reduces cable clutter and helps prevent accidental power loss, making it easier to deploy in cafes, drive-thrus, and kitchen stations where space is limited.
