For whatever this means, Apple released an update to Epson printer drivers for 10.6 and later.
I gather that yours was just a comment in passing (given artie's signature).
Printer driver updates are usually available directly from manufacturers considerably earlier than Apple's update of same.
I'm not sure whether Apple actually vets the updates and/or tweaks them in some fashion (such as only passing through versions which they continue to support) prior to putting them on the Support-Download site or via Software Update.
