Washington Post: Americans waste $10 billion each year on name-brand ink. So we tested low-cost options including remanufactured cartridges, ink injection kits — and even making our own.
My advice: get a mono laser printer. Printing is handy but relatively infrequent for a lot of people these days. If that’s your use case, mono laser is the way to go. Toner does not dry out or go bad.
There is a safety concern that you shouldn’t clean anything involving toner with ammonia-based products (window cleaners, etc.) It reacts with the plastic in the toner. Isopropyl alcohol can be mixed with a smaller ratio of water to use as a cleaner. I do agree with the original message and always recommend people buy laser over inkjet for most tasks.
