Hi, I've just set up an Epson XP 635 Wi-Fi printer. From my Windows 7 Professional laptop (sorry), everything works fine: when I go to print, I can see advanced settings where I can select things like paper type, quality, double-sided, etc. But on my girlfriend's MacBook Pro OS X 10.6.8, I can see a basic print dialogue, but none of these advanced settings anywhere. I feel like I'm missing some simple 'advanced settings' button/mode somewhere, but I can't find anything about that online. Any ideas much appreciated.
