Any particular place people use for faux OEM or re-manufactured laser toner cartridges.
The HP printer is running low on the toner it came with. If I were to buy OEM HP toner, then i may as well throw the printer away and buy a new one (it would be cheaper).
i get kingston ones from amazon and they work fine - 25% the cost of HP ones which at £400 a pop for a full set is an easy risk to take. printer cost £250
