An interesting note to this, Epson Software Updater no longer looks for updates for their printers and says all updates are distributed through Apples Software Update. See screen shot, says this is valid for 10.6 and later, although I don’t ever remember seeing this before.
Of course we all know that this didn’t work in the past. but I noticed that both my p5000 and p9000 driver versions match the current versions on Epsons website, yet I did not download and install those updates yet. But I also don’t remember telling software update to update anything, and there are no Epson updates available or in the recently installed list in my App Store Update window. Not quite sure what is going on.
