SKU CH-KBG4-6AWPW MPN ZM400

A 300 dpi thermal printhead kit designed as a direct replacement for the Zebra ZM400 printer

  • Sharp 300 dpi output for clear labels and barcodes
  • Direct drop-in fit for Zebra ZM400 printers
  • CE certified for safety and compliance
  • Ready-to-install kit with 79801M printhead included
  • Reliable 3.7 V operation for consistent performance

Replacement Printhead Kit 300 dpi

This Graviton ZM400 printhead kit replaces the original 79801M component in Zebra ZM400 printers. It delivers 300 dpi thermal output for barcode and label applications. The unit is supplied new and CE certified for compliance. Install it to restore print quality on a worn or damaged head.

Practical Limits of Thermal Interface

Thermal printing at 300 dpi sets a fixed resolution ceiling that cannot be exceeded by this head. Output depends on compatible media and correct voltage supply of 3.7 V. The USB output interface is intended for MP3 or MP4 player use, not for printer data transfer. Buyers needing higher resolution or network connectivity cannot meet those needs with this part.

Upgrade From Worn Original Head

This kit replaces a degraded ZM400 printhead that shows streaking, fading or missing dots. The jump is worth it when print quality falls below readable standards for barcodes or text. It does not add features the original printer lacks. Buyers who want colour output, wireless printing or a different form factor will not find those functions here.

Questions about this item

Should I choose the 300 dpi printhead or a different resolution for my ZM400?

The 79801M is a 300 dpi printhead built for the Zebra ZM400. Select this resolution when your labels need finer detail such as small barcodes or graphics.

What does the 300 dpi rating mean once the printhead is installed in the printer?

At 300 dots per inch the head produces sharper text and barcodes than lower-resolution heads, improving scan rates on dense labels.

Which interface does the printhead use and what does it limit in practice?

The printhead connects through the ZM400's native printhead connector, so the printer's own controller and firmware set the maximum print speed and quality.
