The EcoTank ET-4850 splits the difference at 15 ppm black, 8 ppm color

15 pages per minute in black, 8 in color. The EcoTank ET-4850 sits right in the middle of Epson’s tank range — not as slow as the entry-level ET-2850, not as fast as the ET-5850. It’s a sensible middle ground if you want better speed than the budget models without paying for the top of the line.
