Epson Stylus NX415
If you connect it and add it, it will say there is no included driver, and at the moment Epson's site doesn't have a SL driver either, but...
If you add the printer then manually choose the driver from the list. Just choose the Epson NX400 Series and everything works fine, even the scanning. I don't know why 10.6 doesn't think that the NX415 is a NX400 series printer, but it is, maybe just a bug.
Funniest thing though is Epson's suggestions doesn't even mention 10.6 has built in support. it suggest you install the old drivers using ROSETTA. How freaking dumb is that!???
