Samsung ML-1510 / 1710 / 1750 refill bottle

Which company, on 31st July 2002, released the world's first unplug & pour refill bottle for a Samsung ML series laser printer? The same company that released the world's first HP LaserJet do-it-yourself refill kit in 1992. The same company that invented "melt & pour" for refilling single-skinned toner cartridges in 1996.
You can probably see where we're going with this ....... we're guilty as charged.

Prise the original plug out with a screw driver. Pour the toner in. Pop the new orange plug in. Finished. It did take us a couple of years to come up with such refinements as a spout and a plug, but hey, that's the world of high tech innovation for you.
