Ink is one of the most expensive substances in the office and colour ink is doubly so. Be more efficient and choose black and white, and if your printer doesn’t have a print-both-sides options, just print odd pages first, re-insert the paper and print even pages. Expand the margins of what you are printing as often as you can to save on paper.

When the end result doesn’t have to be high quality, use the draft mode in your printer settings. This will not only use less ink, but also print faster.

Many websites let you select printer-friendly versions of their stories, which automatically remove color ink-sucking ads and images, leaving you with nothing but text.

When it’s time to refill, use the refillable cartridges, or shop online to find discount ink sellers that aren’t the name brand cartridges
