You can reduce ink cartridge consumption by thinking before your print as well as reading many items online. I save a lot of documents as pdf format files that I would have printed off in the past. If I need it, I can still print it at a later date. I also scan documents instead of copying them and keeping photocopies. It creates a virtual filing system. It may not work for you but it reduces the need to print everything and store it in boxes.
Taking into account that you are no longer printing for the sake of it, using your own printer or photocopier because you do not want to travel miles to get your printing done is still going to leave with you with some ink cartridges that will empty from time to time.
More than 2 million inkcartridges get sent to landfill each year.
refill your ink cartridge by using local companies preferably but you could investigate www.cartridgeworld.co.uk
