It depends on the model.

At the time I was buying mine, Epson marketed the WorkForce Series as the ones which didn't rip you off on ink, and WorkForce Pro, I believe, was even better.

Read reviews for printing costs, and adjust for the cost of generic ink. That's even true for lasers now; it's rare, but I've seen models designed to rip you off on toner too.
