It doesn\u2019t matter. Any that use the Vivera ink set.
Right now I have a 91 Yellow 775ml and a 70 Magenta 130 ml.
Those are just what I happened to find available when I was looking.
I believe the 70 fits the Z2100 and the 91 fits the Z6100, but I\u2019m not certain.
I have already used up one Magenta cartridge (I had two) and a similar quantity from the bigger Yellow cartridge with zero trouble.
They are also easier to get ink out of. The Epson cartridges must be split open, while you can just insert a syringe into the HP cartridges to withdraw ink. Far less messy.

Would you mind being just a bit more specific as to exactly which HP cartridges you buy, i.e., which model HP printer?
