Epson Printer HELP. New Epson all in one NX625 – I am going crazy – have not been able to get this printer to scan or print – it will only copy and print. Keep getting communication error or invalid operation – downloaded new drivers, bought new USB cable and waiting to hear from Epson. Have always owned Epson’s – but this is a nightmare – iMac about 4 years old in great condition. Any help out there? Had this same model and it worked fine – but this second printer is a no go.Yikes!
