Expected Page Yield and Printing Costs
ISO/IEC 24711 standards determine page yields for LC3337 and LC3339XL cartridges based on 5% page coverage. High-volume business document printing will deplete black ink faster than colour channels, making higher-capacity cartridges the ideal choice for busy offices.
