Yeah, that screenshot below’s the Apple default 'Gimp/Gutenprint' printer driver.
it CAN be useful if the printer doesn’t have a driver from the manufacturer (too old maybe) but the Gimp driver does miss some important features as Digital Dog points out here.
Another clue is : Are media names the same as previous Epson drivers you've used, i.e. is 'Premium Luster Photo Paper' mentioned or are the media types just matte or gloss? This is the proper media options list from an Epson driver
In the System Preferences 'Print and Fax' pane, when installing the printer, it seems important to select the printer name under "use" - if you select 'Airpirint' there, OSX seems to default to the Gimp driver.
