I got DVD/CD printing working on my husband’s iMac, now I’m looking to find the instructions as I upgrade my MacBook Pro. I remember you have to REMOVE the driver provided with Apple and INSTALL one from Epson, and then it worked for me. (I use an old free-with-something version of Discus RE to create the labels.)
Found it! Look here:

As I said, it worked for me.
