Not sure if this is what you are referring to but here goes. In the Epson driver on my 7800, I have about 30 custom paper sizes for my roll papers as well as various paper settings for different papers. Backing up each one and then restoring them individually is tedious. However, on the Utility tab, there is an icon called Export or Import. This will save all of the driver settings for sizes and papers etc to a location and you can also import them back. Is this perhaps what you were after?
