I can't print ! When I activate Printcenter it does not find my printer and quits when clicking "add printer". When I activate "Printer Utility" it works with my printer...meaning the driver (for OS X) is installed. (Epson Stylus Photo 790) I know this is a known problem since I found people complaining about this on another forum. But nowhere can I find the solution. Anybody had this problem and know what to do ?
