As ink generates hazardous waste and packaging waste, it's important to increase your ink cartridges & toners lifetime:

• Set printers default settings to duplex and grayscale
• Extend toners lifespan by shaking gently to redistribute ink
• Change for frugal fonts on your document before printing such as Times New Roman, Cambria, Century Gothic (in size 10), Garamond, Ryman Eco...
• Reduce font size,
• Use grayscale instead of black
