It is quite amazing to know that there is one stop center to find ink or toner easily for your printer. Whatever you need, they have it. You do not need to look in Yellow Pages or to shop around for your toner, inkjet or fax cartridge. And at the price that you cannot get elsewhere as they ordered directly from manufacturer in bulks.
I have changed my printers at home three times so far, from Canon Bubble Jet to Lexmark and back to Canon Pixma. While at the office, we upgrade our HP Laser Jet printer every time the new one comes. So it is quite hassle to find the right toner for the right printer. Maybe it creates no problem for your personal printer as you can take your time to shop around. But it is quite troublesome to get the right toner for printers for office use. Sometimes the supplier has no stock in hand and you have to wait longer or to use the old printer which produce the not so good quality result.
