There are 2 versions of this printer, the T7770D & the T7770DL. The ONLY difference is the size of the ink cartridges/tanks. The T7770D uses cartridges that come in 110ml, 350ml and 700ml sizes. The T7770DL has ink packs that only come in 1.6 liter packs. There is significant savings on a per milliliter basis using the ink packs, however, the inital investmemnt is larger.
