The folder you want will be in the,
and most likely in one of the "prnep00a.inf_amd64_neutral_92a4c727cdf4c2f7" (there are 12 of these in mine, the prnep is the important part, signifies Epson). The fun part will be figuring out which one is the right one. If you can also find the DevID for the printer it would help, as some of the INF's in those folders don't show the printer name but the DevID.
Once you find it it should just be a matter of making a copy of the correct folder and transferring it to the same place in W2008.
