Zebra ZM400 4-Inch Industrial Thermal Label Printer

Key Benefits

• Dual Print Modes: Supports both thermal transfer (ribbon) and direct thermal (no ribbon) — one printer handles all your label media requirements without switching hardware.
• Triple Interface: USB, Serial (RS-232), and Parallel ports ensure compatibility with modern computers and legacy WMS, ERP, or POS systems alike.
• High-Capacity Media: Accepts label rolls up to 5-inch outer diameter, reducing downtime from frequent media changes in high-volume print environments.
• 4-Inch Print Width: Handles labels up to 4.09 inches (104mm) wide at 203dpi — ideal for shipping labels, asset tags, barcodes, and compliance labels.
• Industrial Build Quality: Rugged metal chassis designed for demanding 24/7 warehouse, manufacturing, and distribution environments.
• ZPL/ZPL II Compatible: Industry-standard Zebra Programming Language ensures compatibility with thousands of label design applications and most WMS platforms.

Performance in Use

In a busy distribution centre or warehouse, the ZM400 earns its place on the floor. Whether printing shipping labels for outbound freight, asset tags for inventory management, or compliance labels for healthcare packaging, the dual print mode capability means you switch between ribbon-based thermal transfer for durable long-life labels and direct thermal for short-term use — without buying two printers.

The triple interface — USB, RS-232 Serial, and Parallel — slots into virtually any existing IT infrastructure. Modern WMS platforms connect via USB; legacy ERP and POS systems connect through Serial or Parallel, eliminating the need for expensive adapters or system upgrades. Print speeds of up to 12 inches per second keep up with even the busiest pick-and-pack operations.

The high-capacity 5-inch OD media bay reduces roll change frequency on busy production lines. ZPL/ZPL II compatibility means your existing label templates load and print without modification — just plug in and go.
