  • Reliable barcode output with 203 dpi resolution

Compatible Printhead for Zebra ZM400

This A+ quality thermal printhead replaces the original part in Zebra ZM400 barcode label printers. It is built for businesses that need reliable 203dpi output on thermal paper. The 79800M model delivers a direct fit for existing hardware. Buyers who need higher resolution or a different printer interface should look elsewhere.

Drop-in Installation and Daily Operation

The printhead mounts directly into the ZM400 chassis without adapter brackets or cable modifications. Its electrical interface matches the printer's 220V supply, so no external converter is required. The single-piece packing means the unit is ready to install immediately. Shops that use coated labels instead of thermal paper will not get the intended print quality.

Rated Output and Power Profile

The head is rated for 30Km of printing length under normal operating conditions. It draws power from the printer's 220V feed with no additional cooling hardware specified. A 90-day warranty covers the unit against early failure. Users who run continuous high-volume shifts should monitor print density for consistency.
