I use CS4 with an Epson 3800 for about 9 months. When I print, I get an Epson Stylus 3800 Pro Printing Preferences dialog box with four tabs, Main, Paper, Layout, Utility. Now, I get a dialog that says Printing Preferences (although just now it did say Epson Stylus.... but it only has three tabs, which are quite different. I swear I didn't do anything! Just turned the printer off and on. The dialog box says Version 6.50. The Page Layout tab has a little 1 on it as if there were two tabs or the tab had two pages. The original dialog box is version 5.51 (at least according to their on-line manual). This dialog box seems very generic. It has less choices than my Workforce 30.
