In a frenzy yesterday while trying to get my printer to work and print out very important documents that I needed, I believe that I accidentally uninstalled the printer. I'm attempting to reinstall today and am having no luck. I have the printer connected with the ethernet wire. The printer is an Epson workforce 645. I have an iMac 10.6.8. When I downloaded the driver again from Epson and attempted to go through the installation process, there is no printer showing up when I'm prompted to "add printer" and click on the + sign. Please help before I lose my mind!
