Try the following:
1. Go on the Epson web site and check if there is an updated driver for your printer. Even though you have a new printer, there may be a more recent one.
2. If you are printing via the editor, try printing via the organizer, or, vice versa. The print engines are not the same.
3. If all this fails, go to Edit>preferences>general and click on "Reset preferences on next launch." Close the program and reopen.
