This printer has a max resolution of 1440 DPI, but the driver consistently shows Print Quality as 720 DPI, no matter how much I play with the different driver settings. Epson Support has not been helpful at all with suggestions of playing with the settings (which I have done repeatedly), printing a nozzle check and even printing with a different than Photoshop app (as if that addresses the issue!). I've uninstalled and reinstalled the Epson driver; no difference.
So, your inputs are highly appreciated.
