I just purchased an Epson RX500 all in one and installed the software as directed in the instructions. It works fine while in 10.2 but when I'm using a classic app, it won't print. When I go to the chooser and select the RX500, the "select a printer port" box next to it is blank - the Epson instructions says it should show "USB Port." Whenever I try to print, it keeps telling me I need to select a printer from the chooser. I have uninstalled, reinstalled, and downloaded the latest drivers with no luck. What's going on??
