there is no driver for that printer for that operating system from epson
but if you download the 10.6 driver from this website and re install it. It might work
you will want to delete the printer from preferences / printers first
then run the software and try to add it using the + button and see if it shows up and works.
I am available to speak with you on the phone and log in remotely to work on it with you if you want to pay a little bit extra.
