The limited supply of original print cartridges usually went on weekends to run out. Was very expensive and not always easy to predict when replenishment is necessary. Especially when using the printer is used by the whole family with different requirement. Just then I needed the device for official purposes and ...... again a cartridge empty. The putative reserve package in desk was back already consumed time. The 1000 ml refill ink printer is now my reserve in the DIY basement. Easily fillable, good quality at a low price. The question of why half I did not used before? And how much money I could have saved, I do not want to further discuss. I can strong buy recommendation and the fears, my printer ruining thus only be considered as marketing sales pitch for overpriced branded products.
