Buying compatible cartridges at good price but certainly provided they are recognized by the printer that is not the case of the batch I received. If I have to test the whole lot to find one that works at the risk of throwing the other where the economy is to achieve, I ask you? Review your suppliers and reliability when you certify compatibility. This does not encourage them to repeat the experience in this field especially for a customer like me, you used to order your usually reliable product.
