Between 9010e and 9012e
It's definitely the same device, the difference is the different free instant ink time. However, if you're not a heavy user and print varying amounts per month, you're better off with the regular cartridges.

In my opinion, there is no difference between the 9012 and 9015, but there is with the 9022! You can see this in the green fields of the table on the linked page: https://www.druckerchannel.de/techinfo.p...
