If you use 'XL' or 'high Yield' options for both your printer cartridges and ink, you are on the right path. For example, some high-yield cartridges or toners will cost more but can deliver double your page yield. Also, change your settings on your printer to ensure you get maximum output. For example, the 'Times new Roman' font uses less ink than 'Arial'. So if you want to make a presentation in ‘Arial’, make sure you do all your practice prints in 'Times New Roman'. The same goes for colour printing; you can adjust your printer mode accordingly for test copies compared with final documents. Do not refill your cartridge as soon as your low-ink level warning goes off. You still have printing time left; continue until you see a visible drop-off in your print quality.
