SATO WT4-AXB Series – Compact efficiency for industrial label printing

In an industrial environment where every second counts and labeling accuracy makes the difference between efficiency and chaos, the SATO WT4-AXB Series comes as a robust, compact and highly reliable solution. It is a 4-inch industrial label printer, designed for quick integration into existing infrastructures and intuitive operation, even in demanding environments.

Whether you work in manufacturing, automotive, retail, food or healthcare, this printer gives you the flexibility and performance you need for a continuous, uninterrupted workflow.

Designed for real industrial performance

The WT4-AXB is not just a label printer – it is industrial equipment designed for maximum uptime and low operating costs.

Flexible printing method: Thermal Transfer & Direct Thermal

• Thermal Transfer (TT) – for durable labels, resistant to abrasion and high temperatures
• Direct Thermal (DT) – for fast, ribbon-free applications, ideal in logistics and retail

This flexibility allows you to adapt printing to your application without changing equipment.

Resolution and speed adapted to industrial applications

The SATO WT4-AXB is available in two versions:

• 203 dpi (8 dots/mm) – for standard labels, clear and legible barcodes
• 300 dpi (12 dots/mm) – for labels with fine details, small fonts or complex 2D codes

With a print speed of up to 203.2 mm/sec (8 ips) for the 203 dpi model, you get a fast and efficient production workflow, without jams.

Compact design, industrial strength

Do you have limited space in your production area? No problem. With a height of just 261 mm (optionally 256 mm with footpad), the WT4-AXB is optimized for integration into tight spaces.
