Alain,
Eric (madmanchan) has the right settings, there. I also feed the large sheets with the advance button, as I mentioned in the Gold Silk topic, to avoid scratches.
Meanwhile, welcome to the wonderful latest photoshop printing engine reprogramming screwup, still mostly unfixed despite a well publicized outcry from the professional users. I take it that you are using Windows, and it used to work for you. I have a suggestion for a much better printing solution for you:
Qimage uses your Epson drivers and profiles, does excellent page layout, superb final sharpening, and doesn't have amnesia, isn't in denial, and it's an incredible bargain (no, I don't work for them). I've been very pleased with Qimage's performance. When you save your settings they are saved with the image. Why Adobe can't or won't do that is that they have their (no, I can't say that).
Aloha,
Aaron
