There are no plans to support this resolution.

If you want to try 2880×1440 (which would at least give you more vertical resolution), you can try using the Epson 925 driver. If you really want higher resolution, get the 960, which offers 2880×1440 with 2 picolitre drops; this really does offer visible improvement over the 820, but even on that printer there’s awfully little difference in output quality between 2880×1440 and 1440×720, which is the next resolution choice.
