These printers are technically pigment ink printers. Many users acquiring these printers for general pupose use are likely seeking low cost of operation. Since pigment ink is considerably more costly than dye ink, many will want to use the less costly option of dye. This option is highly recommended as not only is it more economical but will actually render the printer to be more reliable with less clogging and other sediment issues related to pigment ink. The key tradeoff is that pigment ink will not fade for decades. For many users the no fade issue for general printing is very far down the list. Pigment ink is more water resistant as well. So that is also a consideration.

For those that want to retain their printer as a pigment ink printer, that option is also offered.
