I have an Epson R1800, which according to Apple, is supported in Mountain Lion. Now, this printer worked nearly flawlessly until upgrading to ML. Now that I have, the printer just kicks out sheets of blank paper and I am always told that the printer's media isn't loaded correctly. I have tried deleting the printer and adding a new one in the Sys Pref as well as trying the Gutenprint drivers. Nothing is allowing me to print. Has anyone had any issues like this, or able to aid in troubleshooting this?
