Citizen CL-E331XUBNNA Barcode Label Printer

Overview

The Citizen CL-E331XUBNNA is a 300dpi thermal barcode label printer designed for warehouse, logistics, and shipping environments where speed and connectivity matter. It outputs crisp, smudge-resistant labels via direct thermal printing—no ribbon required—making it cost-effective for high-volume operations. The CL-E331XUBNNA supports three connection types (USB, Ethernet/LAN, and serial RS-232), so it integrates into existing WMS systems, POS networks, or legacy infrastructure without requiring rewiring. Print density of 300dpi delivers label-quality barcodes (Code128, QR, UPC, EAN, etc.) and readable text on standard 4-inch-wide media, hitting the resolution sweet spot between cost and readability for most commercial shipping labels.

Compatibility

The CL-E331XUBNNA works with any WMS, inventory, or shipping software that can send raw printer commands (ZPL or ESC/POS) or generic Windows/Mac print drivers over USB or TCP/IP. It is compatible with major parcel carriers (FedEx, UPS, USPS) and warehouse platforms (NetSuite, SAP, Shopify, WooCommerce) when configured with the appropriate label templates. Plug-and-play USB on Windows and macOS; LAN deployment supports DHCP or static IP assignment for centralized print fleet management. Serial (RS-232) is available for legacy conveyor systems or barcode sorters that require direct device communication.
