Replacement printhead for GK420T and GX420T

Thermal-transfer process limits speed

Thermal-transfer printing at 203 dpi requires a matched ribbon and label stock to achieve clean output. The fixed resolution cannot be upgraded, so fine graphics or very small text may appear less sharp than higher-density heads. Print speed is constrained by the thermal-transfer mechanism itself. Buyers needing higher resolution or direct-thermal-only operation should select a different printhead specification.
