Due to bad experiences that I have made with foreign ink in another printer a few years ago, I use for several years only original ink. On a positive note that I am currently saving on a relatively large amount of money compared to buying from a local dealer. On a negative note - as with almost all inkjet printers - is unfortunately, that the price for a complete set (= 5 cartridges) almost to the purchase price of my printer (Canon PIXMA IP 5200) extends as.
