Most Epson drivers will work for Graphic output to even newer Epsons.
Pagestream has several, and I have a few I made for PGS for the higher Rezs.

Define "newer Epsons". The Stylus Color 640, 740, & 840 are the last I know of that are ESC/P2 printers. I have never heard anyone report that any ESC/P Raster printers work on an Atari.
