Digital BW, The Print

Depends on the brand.
I assume the set comes with instructions which will clarify things.

Generally speaking when (if) you need 9 working chips from the OEM cartridges, they can be mixed. In other words they can be replaced when a Epson cartridge is almost (usually not completely) empty.
