SATO CL4NX Plus Industrial Thermal Printer — 609 dpi, AEP & RFID

SATO CL4NX Plus: The Universal Industrial Thermal Printer

The SATO CL4NX represents SATO's first truly universal industrial label printer, engineered to optimize asset management and supply chain efficiency. Designed for high-volume, precision printing, the CL4NX is the industry standard for 4-inch thermal printers. Built with a rugged die-cast aluminum frame, this printer is designed to withstand the rigors of industrial environments while maintaining the highest level of print accuracy.

609 dpi: Ultra-High Resolution for Micro-Label Applications

The CL4NX Plus's defining technical advantage is its 609 dpi print resolution — available as a factory-configured option and one of the highest resolutions offered by any 4-inch industrial thermal printer. At 609 dpi, bar widths as narrow as 0.042mm can be printed with consistent edge definition, enabling applications that are simply not achievable on standard 203 or 305 dpi printers:

• Electronics component labeling — PCB identification labels, SMD component reels, and board-level asset tags requiring DataMatrix or QR codes in spaces under 10mm × 10mm
• Pharmaceutical unit-dose labeling — serialized drug labels meeting GS1 DataMatrix density requirements for unit-of-use packaging
• Laboratory specimen labels — fine text and compact 2D barcodes on vials, slides, and cassettes
• Jewelry and small product tags — legible text and scannable codes on label areas under 1 square inch

The "Plus" model further enhances 2D barcode scanning accuracy and offers faster print speeds compared to the base CL4NX, ensuring every micro-label is crisp and compliant at production throughput.

AEP: Application Enabled Printing — Smart Standalone Operation

The CL4NX Plus is equipped with SATO's AEP (Application Enabled Printing) technology, transforming the printer into a standalone processing hub. AEP allows custom applications to run directly on the printer, enabling it to communicate with external devices — barcode scanners, weighing scales, keyboards, and databases — without a PC connection. This reduces system complexity, saves valuable floor space, and streamlines labeling workflows at the point of use.

Common AEP use cases include: weigh-price labeling at packaging stations, scan-to-print label reprinting from a handheld scanner, and automated label triggering from a PLC or conveyor sensor — all without a dedicated workstation PC at each print point.

Universal Connectivity & Field-Upgradeable RFID

The CL4NX Plus offers the most comprehensive standard connectivity in its class: USB 2.0 (Type A & B), Ethernet (IPv4/IPv6), RS-232C Serial, IEEE1284 Parallel, and Bluetooth — all included as standard. Optional dual-band Wi-Fi (802.11 a/b/g/n) enables wireless deployment for modern cloud-based or mobile environments.

The printer also supports field-upgradeable UHF RFID encoding, allowing UHF RFID capability to be added after purchase without factory return. Security features include WPA2 and 802.1X support alongside password-protected menu access — meeting enterprise IT security requirements.

Intuitive Maintenance & Maximum Uptime

The CL4NX features a 3.5-inch full-color LCD display with multi-national language support. When an error occurs, the printer displays a high-resolution video guide walking operators through the resolution step-by-step — eliminating the need for printed manuals or service calls for routine issues. The tool-less printhead and platen roller replacement system enables operators to swap critical components in under one minute. The 8.6-inch OD media roll capacity — one of the largest in the 4-inch class — reduces roll change frequency during high-volume production shifts.
